Both components are part of the gas pedal sensor (PN#996.606.115.00). In addition to P codes, there are separate DTC (diagnostic trouble codes) and are either:
P1219
- 256 Accelerator pedal – Signal Implausible
Potentiometer 1 or 2 outside the operating range.
Potentiometer 1 to potentiometer 2 implausible.
P1577
- 427 Accelerator Pedal Potentiometer 1 – Signal Implausible
Accelerator Pedal Potentiometer 1 – Below Limit
Accelerator Pedal Potentiometer 1 – Above Limit
To isolate which problem is present, this needs to be checked with a DMM (or PST2 or PIWIS testers). Both potentiometers operate on a separate 5V power supply from the DME control module. Potentiometer 2 has a series resistor the size of the bulk resistance, so that its value only has half the inclination of potentiometer 1.
Unfortunately, if found faulty, the remedy is to replace the gas pedal sensor - $300+.
But, there may be another issue.
They would have likely disconnected the battery before working with the trunk cable lever due to the side impact airbag sensor being located in the same area. If so, when reconnecting, if they didn't have the key out of the ignition (or in position 1 or 2), they may have generated a fault code resulting in the CEL. The thing to try is disconnecting the battery for 5 or more minutes, then reconnect battery, switch on the ignition, wait one minute,
Do Not press the accelerator, and finally switch off the ignition for at least 10 seconds. Then restart the car and re-check for faults. You can also check to be certain that no debris or such is obstructing the gas pedal .
If the Gods of Uusikaupunki are smiling on you, this may clear the code.
