What is P0135 Fault-Error code?
P0135 Fault-Error code is an OBD-II (On-Board Diagnostics II) error code received from a vehicle. This error code indicates a problem with the oxygen sensor (O2 sensor) heating circuit. Here is information about the meaning, causes, symptoms, identification, correction and severity of the P0135 error code:
Meaning of P0135 Fault/Error code:
The P0135 Fault/Error code indicates a problem with the heating circuit of the first bank and first bank (usually left front) oxygen sensor (O2 sensor). This heating circuit warms the sensor in cold weather conditions to ensure that the oxygen sensor operates quickly and produces accurate data.
Causes of P0135 Fault/Error code:
The main reasons for the P0135 Fault/Error code may be:
Defective oxygen sensor heating element.
Problematic cables or connections of the oxygen sensor heating circuit.
The sensor produces insufficient data in cold weather conditions due to the oxygen sensor heating circuit not working.
P0135 Fault/Error code Symptoms:
Symptoms of the P0135 Fault/Error code may include:
Check Engine light comes on.
Decrease in fuel efficiency.
Irregular engine operation.
Engine having difficulty starting in cold weather conditions.
How to Determine P0135 Fault/Error code:
The P0135 Fault/Error code is obtained from the vehicle using an OBD-II scanner or diagnostic device. This code is one of the error codes stored in the vehicle's computer memory.
Errors Made While Correcting P0135 Fault/Error code:
The following errors should be avoided when correcting the P0135 Fault/Error code:
Instead of replacing the oxygen sensor, just replacing the part to solve the heating circuit problem.
Not checking the connections of the sensor or heating circuit properly.
Just replacing the oxygen sensor due to the sensor not working properly in cold weather conditions.
How Serious is the P0135 Fault/Error code:
P0135 Fault/Error code may affect the fuel efficiency and emissions of the vehicle, problems may occur especially in cold weather conditions. It is therefore a serious problem, but does not pose an immediate danger.
P0135 Fault/Error code Solution:
Solving the P0135 Fault/Error code can be done by the following methods:
Replacing the faulty oxygen sensor heating element: Replace the faulty element with a new, suitable heating element.
Checking the connections: Make sure that the cables and connections of the heating circuit are correct.
Professional help: If the problem is complex or there are other problems that need to be corrected, contact an automotive service.
Things to consider regarding the P0135 Fault/Error code include the steps necessary to detect and fix the problem. Therefore, if you see this error code on your vehicle, it is important to consult a professional mechanic to get the problem resolved as soon as possible.
