02 Sensor Heater Control Circuit

Vehicle emissions could be increased due to this problem.

02 sensor heater control circuit.

The heater in the oxygen sensor helps get the sensor up to operating temperature faster in order to improve fuel economy and emissions. First is the positively controlled type of circuit. It stands for 02 sensor heater circuit malfunction bank 2 sensor 1. If the o 2 sensor heater circuit s negative wire goes directly to ground look for a short to power problem.

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. When you start the engine the engine control module tests the o2 sensor heater circuit. This code means that the bank 2 sensor 2 oxygen sensor is not warming up properly due a problem in the oxygen sensor heater circuit. Fixing problems involving the o2 heater circuit wiring or element resistance may require rewiring or electrical expertise.

All of the same diagnostic steps apply. Code p0050 is the most closely related code to p0030. The o 2 sensor s heater circuit is controlled in one of two ways. Never assume that the heater oxygen sensor is already bad and needs replacement.

Replace the sensor and then re check. The p0161 trouble code identifies that there is a problem with the heater control circuit in the bank 2 sensor 2 oxygen sensor. So it is essentially the same code but for the opposite bank of the engine. If the ecm detects any delays or failures it will output diagnostic trouble code p0135.

The ho2s2 heated oxygen sensor 2 sensor calculates the air to fuel ratio of the vehicle s exhaust. Usually the heater circuit in this case is controlled by a relay. Should the circuit of the control check out then there s a good chance it s a case of a bad oxygen sensor. It warns about an issue with the bank 2 sensor 2 oxygen o2 sensor s heater circuit.

The onboard diagnostic obd code p0135 is an oxygen sensor heater circuit malfunction in bank 1 sensor 1. O2 sensor heater circuit malfunction bank 1 sensor 1 what the p0135 code means. The p0037 code is set when the ecm detects that the ho2s2 on bank 1 has a malfunctioning heater element. Remove the relay and retest the circuit.

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. How do i fix p0135.
