Question about 2001 Toyota Camry

My 2001 Toyota Camry will not accelerate. The pedal gives no response to the engine. If I replace the throttle position sensor would that be all I need to look at?

I would not just go buy a tps on a guess
first check to see if you can bring the throttle up by hand at the motor where the throttle cable connects to the throttle body it may be a cable that broke

I would check the physical throttle cable assembly before i replaced the sensor, if the cables are moving freely then yes try the sensor

Testimonial: "I found that the pedal is connected to a potentiometer like device that is attached to the sensor. So drive by wire basically. It appears to be ok."

93 toyota Camry 6 cylinder starts but dies when you touch gas pedal tried to check codes again but light won't flash did full tune up, coil, and throttle position sensor


It could be your air intake tube has cracks between the ribs. When you press the accelerator pedal, the engine rocks and opens up a giant vacuum leak. Duct tape will work in a pinch.

Starts and idles, no accelerator response.


Your Denali has Throttle Actuator Control (TAC) System - Electronic throttle control ! Are there any messages on the driver information center ? Reduced engine power ?
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.


You need to have it checked for DTC'S - diagnostic trouble codes , probably a accelerator pedal position (APP) sensor or TPS - throttle position sensor !

How to know difference between throttle or pedal position control sensor problem?


Codes tell you where to look. But a scanner will tell you results. A throttle position code will tell me to look at the sensor at the fuel pedal. That's where it is at on some cars, usually newer. The way to tell the difference is that the throttle body on the engine will have a big control module/box on the side of it. The the TPS will be at the fuel pedal.

Car starts but the engine does not reve when I


either broken accelerator cable or broken throttle position sensor, open the bonnet and see if the gas pedal actually turns the throttle, if the throttle is turning then the fault is in the TPS - http://cgi.ebay.co.uk/TOYOTA-AVENSIS-CAMRY-RAV-4-THROTTLE-POSITION-SENSOR-GEN_W0QQitemZ260532390938QQcmdZViewItem?rvr_id=&rvr_id=&cguid=504ea2ab1260a0aad422e2a2ffc2aa49#ht_879wt_940
That should fix it, simple to fit. one out one in + reattach the connector.

On a 04 camry with 2.4 ltr engine, can I replace just the throttle position sensor or do i have to replace the entire throttle body? The engine code said faulty throttle body.


I think the terms "Throttle Positon Sensor", TPS and "Throttle Body" can be misleading at least in regards to the 04 Camry.

My 04 Camry gave a diagnostic reading of P2121 for my problem "Throttle PEDAL position switch D circuit". However, we changed out the complete Throttle Body/TPS (Toyota Part #22030-0H020) that did NOT fix problem.

The 04 Camry TPS Electronic Module "Throttle Positon Sensor" is factory assembled and riveted to the side of the throttle body. The only way to service/inspect it would be to cut off or drill out the rivets. Not sure you could open the darn thing if you got it off, but that seems to be the only way Toyota sells them!!

Hopefully a new Throttle PEDAL Position Sensor (Toyota Part # 78010-33010 PEDAL ASSY, ACC)
will fix it. This is located under the dash near the accelerator pedal.

So, now I would recommend FIRST to replace the "Throttle PEDAL Positon Sensor" (it is much, much cheaper) and then the Throttle Body/TPS assembly!! Unless of course, you get a diagnostic code as you did for "faulty throttle body!!

How do you change the accelerator position sensor


check that throttle cable is connected at pedal & throttle lever on intake.look under the hood and have an assistant press the pedal,you should see the throttle lever move.if it dosen't,your cable is not connected or broken.

Engine doen't stay idle at steady rpms rev up and down by itself


Either you have a vacuum leak, a bad throttle body position sensor, or a bad throttle body.

If the throttle body is drive by wire (electronic) then it would be a bad throttle body.

If the throttle body is drive by cable (manually driven by a cable connected to the gas peddle) then it would be a bad throttle position sensor.

If the throttle body is bad the check engine light wil lbe on. If it is on have your codes read at your local parts dealer for free, and this will give you a clue as to which pices/parts you need to replace.

Have the car leak tested and the vacuum linse inspected for leaks as well.

2000 toyota tundra has no throttle response during extreme cold


This throttle body has a TPS ( throttle position sensor) and a Accelerator pedal sensor on it. The TPS is on the drivers side and the APS is on the pass side of the throttle body. When this happened your check engine lite came on then went off when it warmed up and acted normally. The code is still in History codes. Check it with a scan tool. I foget the code number but if it come up with the APS code in History, replace that sensor....not the TPS. It is a sealed sensor that gets moisture in it when the seal deteriates and it freezes in very cold weather.
