Light's on , have a vehicle scan done . Check code's . wrench light on ? .
Wrench Warning Indicator (Base Instrument Cluster)
The instrument cluster receives the powertrain status from the PCM over the HS-CAN. When a powertrain system concern is detected, the PCM sends the instrument cluster a command signal to illuminate the wrench warning indicator. If the 4WD control module detects a failure with the 4WD drive system, the 4WD control module sends a message to the instrument cluster over the CAN to illuminate the wrench warning indicator. On 4.6L engines, if the transmission control module (TCM) detects a failure with the transmission, the TCM sends a message to the instrument cluster over the CAN to illuminate the wrench warning indicator.
Plus The electronic throttle control system can turn on the wrench light.
It should be noted that the ETC system illuminates a powertrain malfunction indicator (wrench) on the instrument cluster when a concern is present. Concerns are accompanied by diagnostic trouble codes (DTCs) and may also illuminate the malfunction indicator lamp (MIL).

2007 PCED On Board Diagnostics SECTION 1: Description and Operation Procedure revision date: 08/10/2006 Torque Based Electronic Throttle Control (ETC)
The torque based ETC is a hardware and software strategy that delivers an engine output torque (via throttle angle) based on driver demand (pedal position). It uses an electronic throttle body, the powertrain control module (PCM), and an accelerator pedal assembly to control the throttle opening and engine torque. The ETC system replaces the standard cable operated accelerator pedal, idle air control (IAC) valve, 3-wire throttle position (TP) sensor, and mechanical throttle body.
Torque based ETC enables aggressive automatic transmission shift schedules (earlier upshifts and later downshifts). This is possible by adjusting the throttle angle to achieve the same wheel torque during shifts, and by calculating this desired torque, the system prevents engine lugging (low RPM and low manifold vacuum) while still delivering the performance and torque requested by the driver. It also enables many fuel economy/emission improvement technologies such as variable camshaft timing (VCT) (deliver same torque during transitions).
Torque based ETC also results in less intrusive vehicle and engine speed limiting, along with smoother traction control.
Other benefits of ETC are:

  • eliminate cruise control actuators
  • eliminate idle air control (IAC) valve
  • better airflow range
  • packaging (no cable)
  • more responsive powertrain at altitude and improved shift quality
It should be noted that the ETC system illuminates a powertrain malfunction indicator (wrench) on the instrument cluster when a concern is present. Concerns are accompanied by diagnostic trouble codes (DTCs) and may also illuminate the malfunction indicator lamp (MIL).
Electronic Throttle Body (ETB)
The ETB has the following characteristics:
  1. The throttle actuator control (TAC) motor is a DC motor controlled by the PCM (requires 2-wires). The gear ratio from the motor to the throttle plate shaft is 17:1.
  1. There are 2 designs: parallel and in-series. The parallel design has the motor under the bore parallel to the plate shaft. The motor housing is integrated into the main housing. The in-series design has a separate motor housing.
  1. Two springs are used: one is used to close the throttle (main spring) and the other is in a plunger assembly that results in a default angle when no power is applied. This is for limp home reasons (the force of the plunger spring is 2 times stronger than the main spring). The default angle is usually set to result in a top vehicle speed of 48 km/h (30 mph). Typically this throttle angle is 7 to 8 degrees from the hard-stop angle.
  1. The closed throttle plate hard stop is used to prevent the throttle from binding in the bore (~0.75 degree). This hard stop setting is not adjustable and is set to result in less airflow than the minimum engine airflow required at idle.
  1. Unlike cable operated throttle bodies, the intent for the ETB is not to have a hole in the throttle plate or to use plate sealant. The hole is not required in the ETB because the required idle airflow is provided by the plate angle in the throttle body assembly. This plate angle controls idle, idle quality, and eliminates the need for an IAC valve.
  1. The TP sensor has 2 signal circuits in the sensor for redundancy. The redundant throttle position signals are required for increased monitoring reasons. The first TP signal (TP1) has a negative slope (increasing angle, decreasing voltage) and the second signal (TP2) has a positive slope (increasing angle, increasing voltage). During normal operation the negative slope TP signal (TP1) is used by the control strategy as the indication of throttle position. The TP sensor assembly requires 4 circuits.
  • 5-volt reference voltage
  • Signal return (ground)
  • TP1 voltage with negative voltage slope (5-0 volts)
  • TP2 voltage with positive voltage slope (0-5 volts)
Accelerator Pedal Position (APP) Sensors
The ETC strategy uses pedal position sensors as an input to determine the driver demand.
  1. There are 3 pedal position signals required for system monitoring. APP1 has a negative slope (increasing angle, decreasing voltage) and APP2 and APP3 both have a positive slope (increasing angle, increasing voltage). During normal operation APP1 is used as the indication of pedal position by the strategy.
  1. There are 2 VREF circuits, 2 signal return circuits, and 3 signal circuits (a total of 7 circuits and pins) between the PCM and the APP sensor assembly.
  • 2 reference voltage circuits (5 volts)
  • 2 signal return (ground) circuits
  • APP1 voltage with negative voltage slope (5-0 volts)
  • APP2 voltage with positive voltage slope (0-5 volts)
  • APP3 voltage with positive voltage slope (0-5 volts)
  1. The pedal position signal is converted to pedal travel degrees (rotary angle) by the PCM. The software then converts these degrees to counts, which is the input to the torque based strategy.
  1. The 3 pedal position signals make sure the PCM receives a correct input even if 1 signal has a concern. The PCM determines if a signal is incorrect by calculating where it should be, inferred from the other signals. A value is substituted for an incorrect signal if 2 of the 3 signals are incorrect.
  2. your best ,take your vehicle to a qualified repair .

ok you can take the egr valve off and clean it and if that works you my need to take it to get reset on codes other then that also check vacum lines if these do not work you will have to replace and i hate saying that because this part is high.. good luck to you and have a blessed day..

SOURCE: Where is the ABS sensor

There should be at least 5 abs sensors:
One for low brake fluid------- check master cylinder for low fluid, if it is low( use dot 3 brake fluid ) to fill it.
The other 4 on the back side of each wheel called wheel speed sensors ( which are tied in with abs system).
To really pinpoint the problem, an abs code scanner should be hooked up to it, that would tell what is causing the light to come on.
I think advanced auto parts store or auto zone check it for free (if there is one near you) otherwise some places charge $80.00 to $100.00 for 30 seconds just to retrieve the code.
As far as the cruise control, it could be a vacuum problem or accuator problem, etc. Without testing it's hard to say.

My engine management light stays on after resetting clylinder gasket chech ok

Having it checked only satisfies you - not the sensors that indicate a problem.
Resetting the fault code does not change the sensor.
I have never heard of a Diagnostic trouble code (DTC) that indicated you have a cylinder head gasket problem!

Cruise control, speedometer and odometer don't work

Take it to advance auto have them hook up analyzer to check for fault codes and go from there---you may have an ECM issue or short/loose wire somewhere and/or have you changed anything electrically--if not match to system---will drive ECM nuts--exe some radios are part of the functioning ECM and if these are replaced with after market or unmatched factory issue---problems will arise

Have a 2002 camry check engine light has been on for years. had the catalyst convertor replace 2years ago. still did not fix the problem. have been told that when it was put in that the system needed to...

if you have had a fault with the oxygen sensors for a long time it is possible it has fouled up the catalytic converter.

if the engine check light is the one for routine service and oil change and there is no other fault, it may be possible to reset it yourself.

1. turn ignition key to ACC or LOCK position

2. ensure the odometer is shown and not the trip meters

3. press and hold the trip meter reset button

4. while holding the reset button, turn the key to ON position

5. keep holding the reset button for at least 5 seconds. the odometer will read "000000"
and the light should go off.

if it does not go off then the system will need to be remapped, possible after a new catalytic converter.

try the reset sequence first though

what you could start with is checking to see what trouble codes are being logged for this vehicle...if the engine light stays on, it means the ecu is registering a the means of a trouble the trouble code doesnt tell you how to fix it, but it does give you the direction to go down...judst wondering if you have tried to obtain the trouble codes

My check engine light came on my dash. Audi 2004 2.7 TT

the problem can be caused by vacuum leaks .. in some engines the vacuum hoses pass above the engine where they can get very hot .. they crack, split or just leak .. this causes several bad things to happen including the secondary air injection problem (vacuum operated valves) ... on at least some cars like the passatt there is a vacuum hose kit available that replaces all the critical hoses .. maybe audi has the same type repair kit ..

Is the check engine light considered to be a sensor? My car failed smog due to sensor lights, do i have to go to a dealer to have the problem resolved, or can i do it myself

your car failed because they wont pass you until the light has been reset. the check engine light means the computer detected a fault in a sensor or system that may need"ll need access to a shop or someone who has an obdII diagostic reader and see what was might get lucky and can have the fault reset. If there is a true failure in the system the light will come back on again and repair will be needed. usually the code will tell you which component or sensor has failed. if you like you can purchase one of these devices from an Autoparts store for around $100..these more expensive models are preferred because they not only will reset the fault but will list the code and tell you exactly which sensor has failed... that is if your car has an obdII type system diagnostic connector; usually located under the drivers steering column.

Check engine light comes on because engine computer has detected a fault. It could be anything, from a cheap sensor to an important component out of specifications, to a service reminder. Most shops (not necessarily Honda dealers, ) have the diagnostic equipment to hook it up to your car and tell you what is wrong, before fixing anything. Usual rates for this diagnostic is below $100, including quote for repair.

2004 Mazda MPV -

There could be only one sensor causing all these problems.Usually when one sensor goes bad the other ones will get a bad reading and they will read a fault code.Looks like not to many miles on it.Its worth the fix because those cars run forever.Hope this Helps you and Have a great day

Check Engine light on!!!!!

its the O2 sensor for sure. normally, its good practice to change the sensor when changing out the muffler and cat system. doing it all together will prevent the sensor from faulting.
