Sensor Heater Circuit Malfunction

This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.

Sensor heater circuit malfunction.

Although generic the specific repair steps may vary depending on make model. Usually the heater circuit in this case is controlled by a relay. The control module monitors how long it takes the sensor to warm up and start sending an adequate signal. Sensor 2 would be the second sensor downstream from the engine.

Modern oxygen sensors come with heating elements so that they heat up to the ideal operating temperature quickly. 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. 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.

The control module monitors how long it take the sensor to warm up and start sending an adequate signal. This diagnostic trouble code dtc is a generic powertrain code which means that it applies to obd ii equipped vehicles. The code is triggered when the sensor is taking too long to warm up. The code means that there is a problem with the heater element circuit of the heated oxygen sensor.

First is the positively controlled type of circuit. If the o 2 sensor heater circuit s negative wire goes directly to ground look for a short to power problem. 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. 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.

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. The code means that there is a problem with the heater element circuit of the heated oxygen sensor. The onboard diagnostic obd code p0135 is an oxygen sensor heater circuit malfunction in bank 1 sensor 1.

The o 2 sensor s heater circuit is controlled in one of two ways. This code indicates that the engine control module ecm has tested the oxygen sensor heater circuit and has found a problem with sensor 1 in bank 1. Oxygen o2 sensor heater circuit malfunction bank 1 sensor 1 what does that mean. O2 sensor heater circuit malfunction bank 1 sensor 2 what does that mean.
