02 Sensor Heater Circuit Bank 1 Sensor 1

The pcm monitors the heater circuit and will turn on the check engine light if it finds a problem.

02 sensor heater circuit bank 1 sensor 1. Heated oxygen sensor heater circuit malfunction bank 1 sensor 1 trouble code means that there s a problem with the internal heater of the front oxygen sensor for bank 1. Sensor 1 is the sensor closest to the engine. Enter a new vehicle to add it to your garage and filter the results below. Sensor 2 is the downstream oxygen sensor.

Although the fuel injection computer doesn t know the exact cause of the oxygen sensor s heater problem it usually boils down to one of the following. Bank 1 refers to the side of the engine that has the 1 cylinder. Test 3 oxygen heater element s ohming. The heater circuit is energized through a relay that closes when the engine is cranked.

O2 sensor heater circuit malfunction bank 1 sensor 1 what the p0135 code means. How to repair p0135 code o2 sensor heater circuit malfunction bank 1 sensor 1 oxygen sensors o2s or heated oxygen sensors ho2s need to reach a minimum operating temperature of 750 degrees f to produce an accurate voltage signal. You will test the oxygen sensor and not the sensor harness connector. Code p0030 stands for oxygen o2 sensor heater circuit malfunction bank 1 sensor 1.

P0135 is the obd ii generic code indicating the engine control module ecm has tested the o2 sensor heater circuit and has detected a problem with the bank 1 sensor 1 o2 sensor heater circuit. This test checks whether the o2 sensor for bank 1 sensor 2 if fired or not. 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. This indicates the pcm has detected a problem with the bank 1 oxygen sensor.
