Code P0135 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit.
How do I fix error P0135?
What repairs can fix the P0135 code?
- Replacing the O2 sensor.
- Repairing or replacing the wiring or connection to the O2 sensor.
- Replacing the fuse to the heater circuit after the short is corrected.
Can I drive with a P0135 code?
The P0135 error code is not a serious issue. You can drive your vehicle and don’t need to make repairs immediately. However, as it can lead to poor fuel economy and higher emissions, it is best to address the issue in a timely manner.
Where is P0135 located?
Code P0135 – Heated Oxygen Sensor Heater Circuit Malfunction (Bank1 Sensor1) The air/fuel ratio (A/F) sensor also known as a front oxygen sensor (Bank 1 Sensor1) is installed in the exhaust before the catalytic converter.
What is the code for bank 1 sensor 1?
So your check engine light is on.
What causes P0135?
Code P0135 occurs when the powertrain control module tests the upstream heated oxygen sensor’s heater circuit on Bank 1 and detects a short in the circuit or excessive resistance in the heater circuit.
Is there a fuse for oxygen sensor?
yes, there is a fuse for the o2 heaters. check all the fuses. it may also be a harness issue and needs to be checked as well.
How do I fix code P0137?
What repairs can fix the P0137 code?
- Replacing the O2 sensor for bank 1 sensor 2.
- Repairing or replacing the wiring or connection to the O2 sensor for bank 1 sensor 2.
- Repairing exhaust leaks before the sensor.
What can cause an O2 sensor code?
An engine misfire, leaky exhaust valve or a leak in the exhaust manifold gasket that allows air into the exhaust may also cause this type of code to be set. If an O2 sensor has failed, especially prematurely, the cause often is contamination. Like us, O2 sensors slow down as they age.
What is an oxygen sensor heater?
OBD II equipped vehicles use heated oxygen sensors. Heated oxygen sensors have an internal heater circuit that brings the sensor up to operating temperature more quickly than an unheated sensor.
How much is it to replace oxygen sensor?
between $329 and $379
The average cost for oxygen sensor replacement is between $329 and $379. Labor costs are estimated between $59 and $74 while parts are priced between $270 and $305. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
What is a P0037 code?
The P0037 code is set when the ECM detects that the HO2S2 on bank 1 has a malfunctioning heater element. The heater in the oxygen sensor helps get the sensor up to operating temperature faster in order to improve fuel economy and emissions.
