Jaguar XK8 Throttle Body R&R
I recently experienced a
P1121 code “Pedal Position Sensor” I was
not pleased. But I have
a little history that I think lead me down the wrong path.
It all started when I started the car and the engine started
but would not accelerate and was idling poorly so I turned it off
and restarted and checked the codes.
No codes and all was good on the second start.
I did notice that the cruise control was still on from the
day before. A few weeks
later driving on the highway 55/65mph the car shutdown, I got a
failsafe, traction stability control and transmission failure.
Again no codes and the cruise control was in use.
Turned the car off and restarted and I was on the road again
but this time I turned the cruise control off.
Got home and elected to order a
new brake switch, it was
changed and all was good until about a month later when I started
the car and it began shaking poor idle and a restart did not clear
it and to my surprise a code P1121.
The Torque in the bolts AJ26 torque is 18-24 Nm, and the AJ27 is listed as 21 Nm.
