Detection Condition
WARNING: This page is about a different car, the 2003 Mazda Tribute. However, it is still accessible from the selected car via links, so may be relevant.
- DTC P0704 indicates a malfunction of the CPP switch has been detected.
- DTC P1709 indicates voltage is high or switch is open when voltage should be low or switch should be closed grounding the circuit.
CPP switch is an input to the PCM indicating clutch pedal position (engaged or disengaged). PCM provides a 5-volt reference (VREF) signal to CPP switch. If switch is closed indicating clutch pedal is engaged, output voltage from PCM is grounded through the signal return line to PCM, and there is one volt or less indicating there is a reduced load on the engine. If CPP signal is open (clutch pedal disengaged) input on CPP signal to PCM will be about 5 volts indicating there is a load on the engine.
