P0130 – O2 Circuit (Bank 1, Sensor 1)

P0130 – O2 Circuit (Bank 1, Sensor 1)
For Vehicles With Universal HO2S
Description:                
The powertrain control module (PCM) monitors the heated oxygen sensor (HO2S) for a circuit concern. This DTC sets when the PCM detects a concern with one of the circuits used to determine the oxygen content in the exhaust gas.
Possible Causes:       
 
Open UO2S circuit
Open UO2SGREF circuit
UO2S circuit short to voltage or ground
 
UO2SGREF circuit short to voltage or ground
 
UO2SPC circuit short to voltage or ground
 
UO2SPCT circuit short to voltage or ground
 
Damaged HO2S
Diagnostic Aids:
For Vehicles With HO2S (4-pin)
Description:                
The powertrain control module (PCM) monitors the heated oxygen sensor (HO2S) for a circuit concern. This DTC sets when the PCM detects a concern with one of the circuits used to determine the oxygen content in the exhaust gas.
Possible Causes:       
 
HO2S circuit open
 
SIGRTN circuit open
Incorrect connections
Damaged or corroded terminals
 
Exhaust temperature significantly higher than expected
 
Damaged HO2S
Diagnostic Aids:          Inspect the connectors for signs of damage, water ingress, or corrosion.
