3. EOP sensor power line open circuit inspection
Measure the voltage between the EOP sensor 3P
connector main wire harness side No.1
7
(Brown/White) terminal and engine ground.
Is the measurement within 4.75 – 5.25 V?
YES – Replace the EOP sensor with a new one
and recheck.
NO – Repair open in the Brown/White wire. If the
main wire harness is normal, replace the
ECM with a new one and recheck.
DTC 22-2 (EOP SENSOR VOLTAGE IS TOO HIGH)
• When the DTC code 6-2, 7-2, 10-2, 22-2, 140-2,
141-2, and 143-2 are indicated at the same time, the
ground line (SG2) is open.
• When the DTC code 7-1 and 22-1 or 22-2 are
indicated at the same time, the power line (VCC2) is
open.
1. Symptom reproduction test
Turn the combination switch OFF.
Disconnect the EOP sensor 3P connector
ECM connector A
12
and joint connector 2
them.
Clear the DTC (page 5-6).
• Continue the procedure if the DTC does not
clear.
Turn the combination switch ON.
Measure the EOP sensor voltage using the HDS.
Is the measurement within 0.30 – 4.70 V?
YES – Temporary failure
reappear)
NO – GO TO STEP 2.
2. EOP sensor power line open circuit inspection
Turn the combination switch OFF and disconnect
the EOP sensor 3P connector
Turn the combination switch ON.
Measure the voltage between the EOP sensor 3P
connector main wire harness side No.1
7
(Brown/White) terminal and engine ground.
Is the measurement within 4.75 – 5.25 V?
YES – GO TO STEP 3.
NO – Repair open in the Brown/White wire. If the
main wire harness is normal, replace the
ECM with a new one and recheck.
