Diagnostic Trouble Code (DTC) Charts and Descriptions

P0130 - O2 Circuit (Bank 1, Sensor 1)

Description: This DTC sets when a concern is detected with one of the circuits used to determine the oxygen content in the

exhaust gas.

Possible Causes: • UO2S11 circuit open (if equipped)

• UO2S11 circuit short to ground (if equipped)

• UO2S11 circuit short to voltage (if equipped)

• UO2SGREF11 circuit open (if equipped)

• UO2SGREF11 circuit short to ground (if equipped)

• UO2SGREF11 circuit short to voltage (if equipped)

• UO2SPC11 circuit short to ground (if equipped)

• UO2SPC11 circuit short to voltage (if equipped)

• UO2SPCT11 circuit short to ground (if equipped)

• UO2SPCT11 circuit short to voltage (if equipped)

• HO2S11 circuit open (if equipped)

• HO2S11 circuit short to ground (if equipped)

• HO2S11 circuit short to voltage (if equipped)

• Incorrect connections

• Damaged or corroded pins

• Exhaust temperature significantly higher than expected

• Damaged universal heated oxygen sensor bank 1, sensor 1 (HO2S11) (if equipped)

• Damaged HO2S11 (if equipped)

Diagnostic Aids: Inspect the connectors for signs of damage, water intrusion or corrosion.

KA GO to Pinpoint Test DW.

All others GO to Pinpoint Test DZ.

P0131 - O2 Circuit Low Voltage (Bank 1, Sensor 1)

Description: This DTC sets when a concern is detected with one of the circuits used to determine the oxygen content in the

exhaust gas.

Possible Causes: • UO2S11 circuit short to ground (if equipped)

• UO2SGREF11 circuit short to ground (if equipped)

• UO2SPC11 circuit short to ground (if equipped)

• UO2SPCT11 circuit short to ground (if equipped)

• HO2S11 circuit short to ground (if equipped)

• Damaged universal heated oxygen sensor bank 1, sensor 1 (HO2S11) (if equipped)

• Damaged HO2S11 (if equipped)

Diagnostic Aids: An engine stall condition or an extremely rich air to fuel ratio may set this DTC. Diagnose any engine stall or rich

air to fuel ratio concerns before diagnosing this DTC. Inspect the connectors for signs of damage, water intrusion or corrosion.

P0132 - O2 Circuit High Voltage (Bank 1, Sensor 1)

Description: This DTC sets when an over voltage concern is detected with one of the circuits used to determine the oxygen

content in the exhaust gas.

Possible Causes: • UO2S11 circuit short to voltage (if equipped)

• UO2SGREF11 circuit short to voltage (if equipped)

• UO2SPC11 circuit short to voltage (if equipped)

• UO2SPCT11 circuit short to voltage (if equipped)

• HO2S11 circuit short to voltage (if equipped)

Diagnostic Aids:
