Sensor Heater Circuit Malfunction

Diagnostic trouble code dtc p0161 stands for o2 sensor heater circuit malfunction bank 2 sensor 2 it warns about an issue with the bank 2 sensor 2 oxygen o2 sensor s heater circuit.

Sensor heater circuit malfunction. Usually the heater circuit in this case is controlled by a relay. Modern oxygen sensors come with heating elements so that they heat up to the ideal operating temperature quickly. The control module monitors how long it take the sensor to warm up and start sending an adequate signal. Diagnostic trouble code dtc p0155 stands for o2 sensor heater circuit malfunction bank 2 sensor 1 it is triggered when the vehicle s computer or the engine control module ecm detects an unexpected voltage condition or excessive current draw on the heater circuit of your vehicle s bank 2 ho2.

Sensor 2 would be the second sensor downstream from the engine. First is the positively controlled type of circuit. The control module monitors how long it takes the sensor to warm up and start sending an adequate signal. The onboard diagnostic obd code p0135 is an oxygen sensor heater circuit malfunction in bank 1 sensor 1.

P0135 is a diagnostic trouble code dtc for o2 sensor heater circuit malfunction bank 1 sensor 1. This diagnostic trouble code dtc is a generic powertrain code which means that it applies to obd ii equipped vehicles. This means there is a problem on the o2 sensor on bank 1 and it fails to decrease the time needed to enter closed loop. Error code p0141 is described as oxygen sensor heater circuit malfunction bank 1 sensor 2.

The code is triggered when the sensor is taking too long to warm up. This diagnostic trouble code dtc is a generic powertrain code which means that it applies to obd ii equipped vehicles. This code means that the heated circuit in the oxygen sensor on bank 1 decreases time needed to enter closed loop. Oxygen o2 sensor heater circuit malfunction bank 1 sensor 1 what does that mean.

The o 2 sensor s heater circuit is controlled in one of two ways. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. The code means that there is a problem with the heater element circuit of the heated oxygen sensor. If the o 2 sensor heater circuit s negative wire goes directly to ground look for a short to power problem.

Although generic the specific repair steps may vary depending on make model. Bank 1 refers to the side of the engine that has the 1 cylinder. The code is triggered when the sensor is taking too long to warm up. O2 sensor heater circuit malfunction bank 1 sensor 2 what does that mean.
