CONTROL SYSTEM
Circuit Open/Short Inspection (Heater)
1. Disconnect the PCM connector. (See F43 PCM
REMOVAL/INSTALLATION.)
2. Inspect the following wiring harnesses for open or
short. (Continuity check)
Open circuit
• If there is no continuity, the circuit is open. Repair
or replace the harness.
Front
 HO2S terminal C (harness-side) and ignition
switch
 HO2S terminal D (harness-side) and PCM
terminal 4A (harness-side)
Rear
 HO2S terminal C (harness-side) and ignition
switch
 HO2S terminal D (harness-side) and PCM terminal 4D (harness-side)
Short circuit
• If there is no continuity, the circuit is shorted. Repair or replace the harness.
Front and rear
 HO2S terminal C (harness-side) and body GND
 HO2S terminal D (harness-side) and power supply
 HO2S terminal D (harness-side) and body GND

POWER STEERING PRESSURE (PSP) SWITCH INSPECTION
A6E394032230W01
Note
• Perform the following inspection only when directed.
Continuity Inspection
1. Inspect the following if the power steering is inoperative (See N4 POWER STEERING FLUID INSPECTION.):
• Power steering fluid level
• Power steering fluid leakage
• Power steering fluid pressure
2. Disconnect the PSP switch connector.
3. Start the engine.
4. Inspect for continuity between the PSP switch terminal and GND using an ohmmeter.
• If not as specified, replace the PSP switch.
• If the PSP switch is okay, but PSP PID value is out of specification, perform the Circuit Open Inspection.
