2006 E120 Corolla 1.4 D4D - Fault code & Limp mode (P1121) HELP!!

W123-80's

Hi all,

I'm throwing it back to old school motors with this query!

I'm currently motoring about in a 06 1.4 d4d Corolla with 75k kms (46k Miles) from new.

Faultless motor other than the fact it doesn't have air conditioning!

I've recently being having an issue with engine management light coming on and the car going into limp mode.

When I plugged the car in I'm getting P1121 fault code (Accelerator Pedal Position Sensor). I have reset the fault code and each time i can drive away for about 250/300km until it comes on again and goes into limp mode. It has happened 3 times now, which is obviously too frequent so I need to get to the bottom of it asap as I cant trust the car in its current state.

Does anyone know is this a common fault and/or an easy fix?

I was thinking of taking off the accelerator and giving the wiring plug for the sensor a clean with contact cleaner?

I am never comfortable with sensor/electrical faults.

The car is otherwise perfect. Serviced to within an inch of its life and runs sweet as you would expect from an old Toyota diesel engine with very little miles.

Any help and/or opinions greatly appreciated.

Thanks

Clearing the codes and cleaning the plug won't help.

You'll have to change the sensor.

Is that a fairly straightforward job?

Seems an unusual thing to go?

It's quite common, change it out
