Customer:

The code that keeps coming up is CEM-3F93 and this has gone on for over 2 years. When the codes are cleared its ok for 2 weeks-or-2 months then returns . The revs go to 2000/2500 but no higher. It was just the same before the pedal was changed. keith

Enes : Problem is not gas pedal most cases
Enes : you must replace all terminals at gas pedal connector volvo has updated terminals for that code if keeps coming back
Enes : so new terminals replace all than check wiring from gas pedal to cem for loose terminals and replace on cem terminals for gas pedal
Enes : do cem reload software
Enes : and check all connectors at cem that they snapped and zip tied
