Make:
Dodge
Code:
B1E2F
Definition:
O2 Sensor Circuit (Bank 1-Sensor 2) Short to B+
Description:
Engine started,battery voltage must be at least 11.5v,all electrical components must be off,the ground between the engine and the chassis must be well connected,the exhaust system must be properly sealed between the catalytic converter and the cylinder head,and the oxygen sensor heater for oxygen sensor before the catalytic converter must be properly functioning.The ECM detected a voltage on the O2 sensor circuit that was outside the parameters to function properly.Note: For resistance testing of sensor heating,oxygen sensor should be cooled to ambient temperature.High temperatures at oxygen sensor may lead to inaccurate measurements.
Cause:
 Oxygen sensor (before catalytic converter) is faulty Oxygen sensor (behind catalytic converter) is faulty Oxygen sensor heater (before catalytic converter) is faulty Oxygen sensor heater (behind catalytic converter) is faulty Circuit wiring has a short to power or ground Engine Component Power Supply Relay is faulty E-box fuses for oxygen sensor are faulty Leaks present in the exhaust manifold or exhaust pipes HO2S signal wire and ground wire crossed in connector HO2S element is fuel contaminated or has failed ECM has failed
