Question about Ford Cars & Trucks
Which sensor is at fault, I had the check engine light on over a year ago and had no problems and it just needed reset
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:
Electronic Throttle Body (ETB)
The ETB has the following characteristics:
The ETC strategy uses pedal position sensors as an input to determine the driver demand.

need to set tires at correct pressure you can find a sticker on the inside of drivers door to tell you the correct pressure after you do that it sould reset the light after you drive

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.
