I installed my JWT popcharger couple weeks ago, and the CEL light turns once each weeks, the first 2 time I thought I might just need to reset the ECU, since it has a different air flow. But what happened last night at midnight was I stop at a traffic lights, and just when I was giving gas to start the car, I've notice the engine won't rev and higher at 700 rpm, I had no power on the car, so I pull over and restart the engine. At frist I thought it might be just some people've been experience the stalling issuse after they installed their JWT Popcharger. Well of course the CEL come on the 3rd time, I went to Auto Zone and got a OBD2 reader. It turns out it's telling me I'm getting code: P2135 Voltage Correlation TPS/ Pedal Position Sensor/ Switch A/B.

Has anyone had this error read on their car before?? Is it hard to fix??

Now TPS I think it stands for Throttle Position Sensor, but can someone please tell me where is that loacted. Thank You

 

I think I hear your Z asking for the dealer!

If your really concerned, put back the stock air box and reset your ECU (disconnect the battery). Then see if the error still occurs! Good Luck.

P.S.......Make sure you MAF sensor is properly connected.

 

The throttle position sensor is the unit mounted between the neck of the upper plenum and the black plastic intake tube. Did you accidently touch or move the butterfly plate within the throttle body when you had the intake tube removed? Did you disconnect the harness connected to the TB? If so, check the connections, it may have come loose.

You can try these two procedures to see if they clear the problem.

Accelerator Pedal Released Position Learning ABS009AS
DESCRIPTION
Accelerator Pedal Released Position Learning is an operation to learn the fully released position of the accelerator pedal by monitoring the accelerator pedal position sensor output signal. It must be performed each time
harness connector of accelerator pedal position sensor or ECM is disconnected.
OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON and wait at least 2 seconds.
3. Turn ignition switch OFF and wait at least 10 seconds.
4. Turn ignition switch ON and wait at least 2 seconds.
5. Turn ignition switch OFF and wait at least 10 seconds.

Throttle Valve Closed Position Learning ABS009AT
DESCRIPTION
Throttle Valve Closed Position Learning is an operation to learn the fully closed position of the throttle valve by monitoring the throttle position sensor output signal. It must be performed each time harness connector of
electric throttle control actuator or ECM is disconnected.

OPERATION PROCEDURE
1. Make sure that accelerator pedal is fully released.
2. Turn ignition switch ON.
3. Turn ignition switch OFF and wait at least 10 seconds.
Make sure that throttle valve moves during above 10 seconds by confirming the operating sound.

 

Just putting a pop charger on should'nt do that.

 

I had this error on my G35c ... went to dealer and 1 hr later it is fixed.... to total on warranty was $1K

They replaced the throttle body and a gasket

 

I think your TB needs calabration..
Do the instructions above and should be fine.

 

I'm out of my warrenty 39000... and to make sure the throttle valve moves, we are talking about the tapping noise that we heard coming from the Engine, I just want to make sure.

 

what kind of sound should I be expecting to hear on Throttle Valve Closed Position?? do I need to open my hood to heard it?? and on both procdure I don't need to start up the engine, right?

 

this is off the topic but does the obd2 reader turn off the check engine lite?

 

yes mr pharmd most obd2 readers will shut off the light,but if there is still a problem it will come back on.
