~ ECU No.3(IMP ground)
- Measuring voltage: 0.1[V] ~ 4.9[V]
Remarks : Measuring unit of voltage : Voltage [V]
6) If the measured voltage is not normal,
Check the ‘P’ electric wire, ‘P/G’ electric wire, ‘P /L’ electric wire to see if they have been broken
or have short- circuited.
Replace the MAPAT sensor with new one and it rechecks.
If the measured voltage is normal,
Check the ‘P’ electric wire, ‘P/G’ electric wire, ‘P/L’ electric wire to see if they have been broken or have
short- circuited if there is a bad contact of terminal No. 3, No. 26, No.28 of ECU coupler.
