CONTROL SYSTEM
Circuit Open/Short Inspection (Heater)
1. Disconnect the PCM connector. (See F43 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 N4 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.
Specification
Circuit Open Inspection
1. Disconnect the PCM connector. (See F43 PCM REMOVAL/INSTALLATION.)
2. Inspect the following harness for open or short. (Continuity check)
Open circuit
• If there is no continuity, the circuit is open. Repair or replace the harness.
PSP switch terminal (harness-side) and PCM terminal 1Z (harness-side)
Short circuit
• If there is continuity, the circuit is shorted. Repair or replace the harness.
PSP switch terminal (harness-side) and body GND
