1) Connect the scan tool.
2) Turn OFF the ignition switch for 1 minute or more.
3) Start the engine.
4) Observe the DTC information with a scan tool. Is DTC P0697 set at the same time?
Yes
Go to DTC P0697 diagnosis.
Refer to "51.Engine Control 1A.Troubleshooting(4JJ3 without DPD) DTC P0697 Sensor Reference Voltage 3 Circuit".
No
=>Go to Clutch pedal stroke sensor signal voltage check.
1) Observe the Clutch Stroke Sensor Voltage parameter on the scan tool. Is the Clutch Stroke Sensor Voltage parameter less than or equal to the specified value?
Value: 0.3 V
Yes
=>Go to Clutch pedal stroke sensor 5 V reference voltage check.
No
Go to Intermittent conditions of engine.
Refer to "202.Engine 15D.Symptom(4JJ3 without DPD) intermittent conditions of engine".
1) Turn OFF the ignition switch.
2) Disconnect the clutch pedal stroke sensor harness connector (C73).
3) Turn ON the ignition switch.
4) Measure the voltage between the clutch pedal stroke sensor 5 V reference circuit (pin 5 of C73) and the body ground with a DMM. Is the voltage more than or equal to the specified value?
Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Value: 4.5 V
Yes
=>Go to Clutch pedal stroke sensor signal voltage check using fused jumper wire.
No
=>Go to Inspection for open circuit in clutch pedal stroke sensor 5 V reference circuit.
1) Connect a fused jumper wire between the 5 V reference circuit and the signal circuit of the clutch pedal stroke sensor (pins 3 and 5 of C73).
Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
2) Observe the Clutch Stroke Sensor Voltage parameter on the scan tool. Is the Clutch Stroke Sensor Voltage parameter more than or equal to the specified value?
Value: 4.5 V
Yes
=>Go to Clutch pedal stroke sensor harness connector inspection.
No
=>Go to Inspection for open circuit and short circuit in clutch pedal stroke sensor signal circuit.
1) Inspect the clutch pedal stroke sensor 5 V reference circuit between the ECM (pin 28 of C9) and the clutch pedal stroke sensor (pin 5 of C73) for an open circuit or high resistance. Is the result normal?
Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to ECM harness connector inspection.
No
Repair the circuit as necessary.
1) Inspect the clutch pedal stroke sensor signal circuit between the ECM (pin 29 of C10) and the clutch pedal stroke sensor (pin 3 of C73) for the following. Is the result normal?
Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
=>Go to ECM harness connector inspection.
No
Repair the circuit as necessary.
1) Inspect for poor connections at the clutch pedal stroke sensor harness connector (pins 3 and 5 of C73). Is the connection status normal?
Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
Replace the clutch master cylinder.
Refer to "5.Transmission, Transaxle 5E.Clutch System(MVL) clutch control removal".
Refer to "5.Transmission, Transaxle 5E.Clutch System(MVL) clutch control installation".
No
Repair the connections as necessary.
1) Inspect for poor connections at the ECM harness connector (pin 28 of C9 and pin 29 of C10). Is the connection status normal?
Refer to "LHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Refer to "RHD Engine Control (4JJ3 without DPD)" in the ETM (wiring diagram). (Open using the ETM viewer.).
Yes
No
