Throttle actuator control range/performance

DETECTION 

CONDITION

• The PCM compares the actual TP with the target TP when the engine is running. If the difference is more 

than the specification, the PCM determines that there is a throttle actuator control circuit range/
performance problem.

• DTCs are stored in the PCM memory.

POSSIBLE 

CAUSE

• Throttle actuator malfunction

• Throttle valve malfunction

• PCM malfunction

DTC P0703

Brake switch No.1 circuit malfunction

DETECTION 

CONDITION

• PCM monitors changes in the input voltage from the brake switch. If the PCM does not detect the voltage 

change while alternately accelerating and decelerating 8 times, the PCM determines that the brake switch 
circuit has a malfunction.

Diagnostic support note

• This is a continuous monitor (CCM).

• MIL 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 the first drive 

cycle.

• FREEZE FRAME DATA is available.

• DTCs are stored in PCM memory.
