Hi

Check engine light, P2135 diagnosis is throttle pedal sensor/switch A/B voltage correlation

I had this in May, fitted a brand new throttle body and no problems since.

Now it's back, surely not the throttle body again?

Thx

The answer is in your message the fault coming from the pedal sensor not the body so you need to change the pedal for a brand new you can do the repair yourself

Yes I did wonder if it was the pedal but that message 'could' still refer to the throttle body where the input from the accelerator pedal is calculated?

Yes I'll see how it goes. I can clear the error with the OBD reader for now. Pedals seem cheap enough to buy.
