P0641
The 5-volt reference 1 circuit provides 5 V to the accelerator pedal position (APP) sensor 2, A/C refrigerant pressure sensor, throttle position sensor, exhaust gas recirculation (EGR) valve, turbocharger vane position sensor, clutch pedal position (CPP) sensor and diesel particulate filter pressure sensor
