DTC P0340, P0345 CMP SENSOR (PHASE)
Revision: 2006 July 2007 FX35/FX45
Specification data are reference values and are measured between each terminal and ground.
Pulse signal is measured by CONSULT-II.
CAUTION:
Do not use ECM ground terminals when measuring input/output voltage. Doing so may result in dam-
age to the ECM's transistor. Use a ground other than ECM terminals, such as the ground.

Refer to EC-360, "
DTC P0335 CKP SENSOR (POS)" .

If DTC P1715 is displayed with DTC P0340 or P0345 first perform the trouble diagnosis for DTC
P0340 or P0345. Refer to EC-367, "
DTC P0340, P0345 CMP SENSOR (PHASE)" .
The MIL will not lights up for this self-diagnosis.
