DTC P0704-00: CPP Switch Input Circuit Problem: Notes

DTC P0704:00	CPP switch input circuit problem
DETECTION CONDITION	The PCM monitors changes in input voltage from the CPP switch. If the PCM does not detect a voltage change while the vehicle runs with vehicle speed above 30 km/h {19 mph}  and stops 8 times  alternately, the PCM determines that the CPP switch circuit has a malfunction. Diagnostic support note  This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle. FREEZE FRAME DATA/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Not applicable
POSSIBLE CAUSE	CAUTION: Inspect the CPP switch with it installed to the clutch pedal, otherwise the CPP switch may not operate normally after inspection. If the CPP switch is removed from the clutch pedal, replace the CPP switch with a new one. CPP switch connector or terminals malfunction Foreign object lodged between CPP switch plunger and clutch pedal contact surface CPP switch malfunction Open circuit in wiring harness between CPP switch terminal B and body ground PCM connector or terminals malfunction Short to ground in wiring harness between CPP switch terminal A and PCM terminal 2J Open circuit in wiring harness between CPP switch terminal A and PCM terminal 2J Driver continues to depress clutch pedal causing mistaken detection by PCM PCM malfunction
