Infiniti G35 (V35). Manual - part 432

DTC P2135 TP SENSOR

EC-609

Specification data are reference values and are measured between each terminal and ground.

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.

Diagnostic Procedure

CHECK GROUND CONNECTIONS

Turn ignition switch OFF.

Loosen and retighten two ground screws on the body. Refer to

EC-159, "Ground Inspection"

OK or NG

>> GO TO 2.
