P2122 code

Question

I have a 2004 Honda Accord v6. The code P2122 came on so I changed the Accelerator Petal Sensor. The Code read Acceleration Petal App Sensor A, Throttle Position Sensor D Circuit Low 2.

When I changed the Acc Petal Sensor the check engine light, TCS light is still on the "D" still flashes.

The vehicle is still difficult to start, no acceleration when stepping on the gas petal and the engine fan comes on immediately.

What could be my next step or what do you think is my problem.

Thank you

Answer 1

P2122 APP sensor A (throttle position sensor D) Circuit low voltage

If the APP is not recieving power from the ECM for its 5 volts refference then yes the PRNDL will not repond, When the "D" light flashes it means there is no input to the sensor. poor connection somewhere. Retry the connection check all the fuse for any open and have the battery disconnected.
