Sensor Heater Circuit Malfunction

This diagnostic trouble code dtc is a generic powertrain code which means that it applies to obd ii equipped vehicles.

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. Although generic the specific repair steps may vary depending on make model. If the o 2 sensor heater circuit s negative wire goes directly to ground look for a short to power problem. The o 2 sensor s heater circuit is controlled in one of two ways.

Bank 1 refers to the side of the engine that has the 1 cylinder. 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. 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. Oxygen o2 sensor heater circuit malfunction bank 1 sensor 1 what does that mean.

First is the positively controlled type of circuit. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. P0135 is a diagnostic trouble code dtc for o2 sensor heater circuit malfunction bank 1 sensor 1. 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. Modern oxygen sensors come with heating elements so that they heat up to the ideal operating temperature quickly. Sensor 2 would be the second sensor downstream from the engine. The control module monitors how long it take the sensor to warm up and start sending an adequate signal.

Although generic the specific repair steps may vary depending on make model. 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. Usually the heater circuit in this case is controlled by a relay.

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. 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 code means that there is a problem with the heater element circuit of the heated oxygen sensor.
