Det är mig veterligen inte särskilt vanligt med fel på gasspjället på bilar som likt din har den nyare typ av spjäll som började monteras på turbobilar från årsmodell 2002 och på sugmotorbilar från årsmodell 2003. Den generiska felkod om du läst ut, P2111, motsvarar på din motor den Volvospecifika koden ECM-91B7. Om den säger VIDA följande:
ECM-91B7 Throttle unit. Faulty signal, B5244T3
Condition
Diagnostic trouble code (DTC) ECM-91B7 is stored if the engine control module (ECM), when attempting to adapt the throttle unit, registers that the movements of the throttle is impeded or that the return spring in the throttle unit is not functioning correctly.
Substitute value
Depending on the fault, the engine control module (ECM) can cut off the supply to the damper motor in the throttle unit. The throttle will then attempt to set itself to the return position.
Possible source
Faulty signal:
The throttle is sticking or is blocked (oil film, dust etc.)
Contact resistance or oxidation in the terminals between the engine control module (ECM) and the throttle unit
Open-circuit, short-circuit to ground or short-circuit to supply voltage in the wiring for the damper motor in the throttle unit
Short-circuit to each other in the wiring for the damper motor in the throttle unit
Defective throttle unit.
