Car recently diagnosed with bad accelerator pedal sensor. I replaced the sensor and my question is, how do you program the new sensor once installed.

Good morning,

There is no programming required. It is a plug and play.

What is the issue?

Plugged the new one in and there was no difference in performance. Still very little power between the engine and the pedal.

Did you have a code set? What lead you to think it was the issue?

Does the engine rev up?

Can you give me the symptoms? As much information as possible.

Was diagnosed by Goodyear Store who advised code indicated a bad sensor. From a standing start it moves off alright but then it hits a point where there is very little power and you have to press the accelerator to the floor and even then there no real surge in power and it takes maybe 10 to 15 seconds to get up to a normal speed. Once up to a normal speed it will maintain that speed but when you press the accelerator to the floor where it would normally kick into like a passing gear there is hardly any power. I replaced the sensor with a new Dorman sensor obtained from Parts Geek, I suppose that sensor could also not be good. There was no difference in performance from the old sensor to a new one.

Okay, let us back up.

What was the code that was set?

This does not sound like the issue at all.

This could be many things like fuel pressure, clogged catalytic converter or timing.

Don't know what the code set was, just going by what Goodyear told me the problem was.

Okay, call them back and ask them for the codes. They may be on your receipt as well.

I need the code to further help you.

According to Goodyear the code was CF1 on P1120 Accelerator pedal position sensor circuit fault.

Okay, the code is for a circuit issue with the sensor, not the sensor. Techs are so quick to condemn a part by the code number. It said APP sensor so they shot it without verifying it is actually bad.

There is a wiring issue with the wiring between the sensor and the PCM.

I would replace your new sensor with the old one and take it back to them and have them do a proper diagnostic for the issue.

They should not charge you for that since they already failed at there attempt the first time.

The sensor needs 2 5 volt signals to it to work correctly. Sounds like one of them may be missing.

Roy

Accelerator pedal position sensor is mounted on the accelerator pedal bracket and it has 2 sensors to detects the accelerator position and a malfunction of the accelerator position's own.

The accelerator pedal position sensor is the voltage applied to the terminals VPA1 and VPA2 of the ECM changes between 0 V and 5 V in proportion to the opening angle of the accelerator pedal.

The ECM judges the current opening angle of the accelerator pedal from these signals input from terminals VPA1 and VPA2 and the ECM controls the throttle motor based on these signals.

If this DTC is stored, the ECM shuts down the power for the throttle motor, and the throttle valve is fully closed by the return spring.

Thanks Roy you've been very helpful. Looks like this could have been easily determined by putting an o-meter on the sensor itself to see if it was bad. I will take your advice. Hopefully I will be reimbursed by Geek Parts for the new sensor I bought through them.
