4. Diagnostic Steps:
Check whether there is control system DTC code other than P0601, P0602, P0604, P0606, P060A, P1516,
Step 1
P2101.
Yes
Replace ECM.
Step 2
2.12.7.46 DTC P0641 P0651
1. DTC Descriptor:
DTC P0641
DTC P0651
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.
Conditions For Setting The DTC
(Control Strategy)
