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

DTC P0704:00 DETECTION CONDITION AND POSSIBLE CAUSE

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 (Mode 2)/Snapshot data is available. The DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	-
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 CPP switch malfunction Open circuit in wiring harness between CPP switch terminal B and body ground Short to ground in wiring harness between CPP switch terminal A and PCM terminal 1BD PCM connector or terminals malfunction Open circuit in wiring harness between CPP switch terminal A and PCM terminal 1BD PCM malfunction
