What does p0135 stand for in check engine light?
The PCM monitors the heater circuit and will turn on the check engine light if it finds a problem. Code P0135 stands for Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). This indicates the PCM has detected a problem with the bank 1 oxygen sensor. Bank 1 refers to the side of the engine that has the #1 cylinder.
What is the O2 sensor heater error code p0135?
Error Code P0135: O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 1. The onboard diagnostic (OBD) code P0135 is an oxygen sensor heater circuit malfunction in bank 1, sensor 1. 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.
How to check for O2 sensor trouble code?
Common mistakes when diagnosing the P0135 code 1 Not checking the O2 wire harness for water entry into the harness cover 2 Not checking the O2 sensor for oil or other contaminants 3 Not scanning the new O2 sensor to make sure the heater circuit works 4 Replacing parts before conducting thorough pinpoint tests and visual checks
What is the OBD code for an oxygen heater?
The onboard diagnostic (OBD) code P0135 is an oxygen sensor heater circuit malfunction in bank 1, sensor 1.
The PCM monitors the heater circuit and will turn on the check engine light if it finds a problem. Code P0135 stands for Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1). This indicates the PCM has detected a problem with the bank 1 oxygen sensor. Bank 1 refers to the side of the engine that has the #1 cylinder.
How do you troubleshoot code p0135 on an O2 sensor?
If your registration is due, you will also fail the emissions test. How do you troubleshoot code P0135 ? This code can only be caused by problems in O2 sensor heater circuit, or by the sensor itself. Typically, heated O2 sensors have four wires – two of which go to the heater circuit and two that are power and ground for the sensor.
What is the diagnostic code for O2 sensor heater?
Cost of diagnosing the P0135 code. P0135 is a diagnostic trouble code (DTC) for “O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)”. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
What does the p stand for in OBD-2?
In this case, the letter ‘P’ indicates a generic powertrain code. If the engine control module detects that the oxygen sensor heater circuit is open, short, or draws too much current based on coolant temperature, the onboard computer will output OBD-II diagnostic trouble code P0135.
How to diagnose a p0135-heater performance Bank 1?
A P0135 DTC says: HO2S Heater Performance Bank 1 Sensor 1 and this means that the PCM (Powertrain Control Module = Fuel Injection Computer) has detected a problem with the front oxygen sensor’s heater element or a problem in the heater’s circuit (wires).
If your registration is due, you will also fail the emissions test. How do you troubleshoot code P0135 ? This code can only be caused by problems in O2 sensor heater circuit, or by the sensor itself. Typically, heated O2 sensors have four wires – two of which go to the heater circuit and two that are power and ground for the sensor.
How much does it cost to repair a p0135 Chevy?
The cost of diagnosing the P0135 CHEVROLET code is 1.0 hour of labor. The auto repair labor rates vary widely across the country, and even within the same city. Most auto repairs shops charge between $75 and $150 per hour.
