Pedal position sensor
I have a 2000 s80 t6 and recently I have been getting a obd code of p0121, pedal position sensor. Is this related to the AMF or the throttle box? Is this a DIY fix.
Thanks,
Andy

RE: Pedal position sensor
Is that in the engine or ABS?
Does it say Brake pedal sensor?
My cheater book says it is throttle position sensor related to the throttle body.

RE: Pedal position sensor
As Tech said, P0121 is a throttle sensor code. The check engine light comes on because the throttle unit requests it to alert the user.
How you have a brake pedal sensor fault with that code is a mystery.

RE: Pedal position sensor
I dont know the code for brake pedal postion sensor. According to the mechanic yesterday, when he scanned the codes with hookups to his laptop, he found a faulty mass airflow sensor . Mass airflow was replaced. The other fault showed brake pedal position sensor fault. He cleared the check engine light,which came back on later in the day, which most likely would be brake pedal postion sensor.My question is ,why would it turn check engine light on? How are they related.

RE: Pedal position sensor
Because if that sensor is bad it cuts the cruise control off.
That is how it is related to the engine module.

tranny shudder
Forgot to mention transmission shudders between 2nd & 3rd gear.I called the volvo dealer about soft ware update, he said since there is no recall, it will cost $160.00 if soft ware is accepted. .If not accepted around $90.00. I understand there is Tech Service Bulletin on this numerous issue, why volvo won't cover the cost is disturbing. How often is it an sth issue, from your experience? The issue of soft ware acceptence or non acceptence, what does that mean? Thanks
