2.12.7.46 DTC P0641 P0651

1. DTC Descriptor:

DTC

P0641

ETC Reference Voltage A # Amplitude Fault

DTC

P0651

ETC Reference Voltage B # Amplitude Fault

As ETC uses two throttle position sensors, its normal working required 5 V reference voltage and low reference voltage is shared
with ETC harness connector terminals A and D. Where A and EO01 terminal No.3 is connected, sharing the low reference voltage.
D terminal and EO01 terminal No.4 is connected, sharing 5 V reference voltage. Malfunction in any circuit will report DTC code
P0641 or P0651.
