STEP
2 INSPECT POOR CONNECTION OF
CALIBRATION RESISTOR CONNECTOR
• Turn engine switch to OFF.
• Inspect for poor connection (damaged, pulled-
out terminals, corrosion, etc.).
• Is there any malfunction?
3 INSPECT CALIBRATION RESISTOR SIGNAL
CIRCUIT FOR SHORT TO GND
• Turn engine switch to OFF.
• Inspect continuity between calibration resistor
terminal A and body GND.
• Is there continuity?
4 INSPECT CALIBRATION RESISTOR SIGNAL
CIRCUIT FOR SHORT TO POWER
• Turn engine switch to ON (Engine OFF).
• Inspect voltage between calibration resistor
terminal A and body GND.
• Is voltage below 1.0V?
5 INSPECT CALIBRATION RESISTOR
• Inspect calibration resistor.
(See F2–83 CALIBRATION RESISTOR
INSPECTION)
• Is there any malfunction?
6 INSPECT POOR CONNECTION OF PCM
CONNECTOR
• Turn engine switch to OFF.
• Inspect for poor connection (damaged, pulled-
out terminals, corrosion, etc.).
• Is there any malfunction?
7 INSPECT CALIBRATION RESISTOR CIRCUIT
FOR OPEN
• Turn engine switch to OFF.
• Inspect continuity between following
harnesses:
— Calibration resistor terminal A and PCM
terminal 37, 62, 89, 11.
— Calibration resistor terminal C and PCM
terminal 91.
• Is there continuity?
8 VERIFY TROUBLESHOOTING OF DTC P1190
COMPLETED
• Make sure to reconnect all disconnected
connectors.
• Clear DTC from PCM memory using WDS or
equivalent.
• Start engine.
• Is same DTC present?
9 VERIFY AFTER REPAIR PROCEDURE
• Perform "After Repair Procedure".
(See F2–86 AFTER REPAIR
• Is there any DTC present?
