Question about 1997 Toyota Camry

1 Answer

Speed Control Problem

First issue was the car accelerate by itself without stepping on the pedal. I Cleaned the throttle body and lubricates the cable's. Now the car runs like it was on cruise control, even though the cruise control was off. Example: I was driving 40mph or any speed, I removed my foot on the gas pedal and the car still running 40mph or any speed. The only way to slow it down is to step on the brake and full stop.

SOURCE: Camry Idles high for a bit at start-up, and now accelerates in a jerky way

you need to replace the coolant temperature sensor. It tells the computer that your car needs a high idle. As far as your running, you got some water displaced in your system. Change out the fuel filter, and pour a can of "Seafoam" in the tank. It will take a few miles, but that should fix your problem.

SOURCE: 2000 Camry Starts but dies down right away

Hello

I just worked on this problem a couple of days ago. If the motor is a 3.0 liter. The idle control valve is located at the bottom of the throttlebody assembly right below the bore for the throttle butterflies..What usually causes this valve to go bad is the mechanical part of the sensor sticks as it becomes sludged or carboned up. Manufacturer claims that the valve cannot be cleaned and should only be replaced....It's a high dollar repair to replace this sensor as your engine coolant flows through this electrical valve. The valve idles the car fast when cold, as the antifreeze gets hot the valve drops the idle down.....I have successfully cleaned several of these valves and cured the dying problems...
First remove the air filter top cover and the tubes that connect to the throttlebody. In the right throttlebody you will see a port right before the butterfly. Under the throttlebody you have a black plastic sensor with a 2 wire terminal. Remove the 2 phillps screws and pull off the electrical part of the valve. you will feel a magnetic pull while removing. Remove slowly and catch the black sealing oring, and there will be a metal washer also.. The shaft that is exposed is the mechanical control of the valve. Rotate the shaft and it should feel sticky if bad..Using a throttlebody spray cleaner spray into the small square port of the right bore, rotate shaft and spray until stickfree.....Reassemble

SOURCE: Car will not start without pressing gas pedal to

Have the idle bypass valve checked, also called idle air control valve.
If that valve is stuck in the closed position, it's not allowing the fuel to bypass the throttle plate to keep it idling, resulting in stalling, but will keep engine running if the pedal is pushed down.

Where is the fuse for cruise control?


Inspection and Verification
NOTE: If any concerns are noted with the speedometer, stoplamps, or horn, address those concerns by referring to the appropriate sections before continuing speed control diagnosis.
  1. Verify the customer concern by operating the speed control system.
  1. NOTE: Any aftermarket modifications, including but not limited to those listed below, may cause the speed control to not operate correctly:
    • Any wiring or lamp modifications affecting the brake lamp operation
    • LED brake lamps
    • Non-factory installed trailer wiring
    • Radios (speed sensitive, auto mute)
    • Remote starters and alarms
    • Lighting and electrical accessory modifications
    Visually inspect for obvious signs of mechanical or electrical damage:
    • Visually inspect the speed control actuator and accelerator controls.
    • Visually inspect the speed control cable without removing it and ensure smooth cable operation. Inspect the speed control cable connection to the throttle body.
    • Visually inspect the accelerator cable without removing it and ensure smooth cable operation. Inspect the accelerator cable connection to the throttle body. Also check for cable interference with the carpet, bulkhead grommet, insulation and instrument panel wiring.

Cruise control stop working light dont show on dash can a fuse be out if so where is it located


There are three fuse's in the smart junction box , do you know where it is ? It's under the dash panel left side ! The fuse's are F2.27- 10amp , F2.32 - 10amp , F2.17 - 15 amp . They power the speed control servo ! Maybe the control switch's on the steering wheel don't work.
A little back ground on the system ! Speed Control The vehicle speed control system consists of the following components:
  • Brake pedal position (BPP) switch
  • Speed control actuator cable
  • Speed control switches
  • Speed control deactivator switch
  • Speed control indicator
  • Speed control actuator
  • Smart junction box (SJB)
  • Principles of Operation
    The speed control system is designed to maintain vehicle a set speed above 48 km/h (30 mph). After the speed control ON switch is pressed, pressing the speed control switch SET/ACCEL will activate the speed control actuator. To increase a set speed, either press and hold for continuous acceleration, or momentarily tap the speed control switch SET/ACCEL for 1.6 km/h (1 mph) acceleration increments. To decrease a set speed, press and hold the speed control switch COAST until the target speed is reached, or momentarily tap the speed control switch COAST for 1.6 km/h (1 mph) deceleration increments. When the speed control system has been disabled by tapping the brake pedal, the speed control switch RESUME can be pressed and the vehicle will return to the original set speed if the vehicle is traveling over 48 km/h (30 mph) and the speed control switch OFF has not been pressed.
    NOTE: The deactivator switch is provided as an additional safety feature. Normally, when the brake pedal is pressed, an electrical signal from the brake lamp circuit to the speed control actuator will deactivate the system. Under increased brake pedal effort, the deactivator switch will open and remove power to the speed control actuator, releasing the throttle independently of the speed control actuator.
    NOTE: The clockspring provides the electrical interface between the steering column wiring and the speed control switches in the steering wheel.
    The inputs to the speed control actuator are:
    • Vehicle speed signal
    • Speed control switches
    • Brake pedal position (BPP) switch
    • Deactivator switch
    The outputs of the speed control actuator are:
    • Speed control indicator lamp
    • Speed control actuator cable controlling the throttle position
    • Inspection and Verification

Throttle revs by its self without using gas pedal, car will keep increasing speed have to control with


Could be two issues. First could be the cruise control. I would try disconnecting the link to the throttle from the cruise and retest. If there is still an issue then your problem can be a throttle position sensor or the onboard computer. This is a hard one to diagnose without seeing the vehicle itself.

Reduced engine power


Have the vehicle checked for DTC'S - diagnostic trouble codes ! Do you know what electronic throttle control is ? The gas pedal assembly has electrical connector an sensors inside ,hooked to the PCM / ECM - engine computer . The engine computer uses these position sensors inputs to control the DC motor on the throttle body to open the throttle plate to control the speed . Plus there are position sensors inside the throttle body to input PCM/ECM to see if it's calculations are corect . Your best bet maybe to take it to a qualified repair shop .
Drive by Wire Function and diagnostics by Wells

Reduced Engine Power Mode
When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
• Acceleration limiting--The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.
• Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.
• Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.
• Forced idle mode--The control module will perform the following actions:
- Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.
- Ignore accelerator pedal input.
• Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.

Throttle pedal position sensor "A" circuit low input


Sounds like the Throttle Plate is sticking

You were fooled into changing the TPS because of the code

Not the way you diagnose vehicle issues

You find out why a sensor--- good or bad set the code

Get some CRC Throttle Body Cleaner & follow the instructions

Don't need much sprayed around the throttle plate

Then have someone step on gas pedal to confirm success

May need the key on

Your low input is the throttle not returning to home position

Almost like the sensor was telling you what was wrong

Fun stuff isn't it & not easy to understand
