To test the O2 sensor #1's heater, we need to know which wire supplies it with power. We also need to know which terminals, of the connector of the O2 sensor itself, are part of the heater element circuit inside the O2 sensor..

P0135 Oxygen O2 Sensor Heater Circuit Malfunction Technical Description. Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1) What does that mean? This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model..
Also, the sensor may be defective, or there is defective wiring, keeping the sensor from sending the required data to the PCM. Other possible causes include: Open power, ground wires or open circuit inside the O2 sensor. manufacturer: sensor mfg: 1 wire: 1 wire: 1 wire: 2 wire: 2 wire: 3 wire: 3 wire: 4 wire: 4 wire: function : general motors: delphi: violet : violet : violet : violet. Two-wire sensors use one wire for the sensor's signal and the other one to power the heater. Three-wire models, use one wire for the signal and the other two wires to power and ground the heater. Four-wire sensors, though, use one of the wires to ground the sensor itself. To identify the wires look at the wiring diagram in your vehicle repair manual..
Problem on the ground side of the O2 sensor heater circuit; Problem on the power side of the O2 sensor heater circuit; O2 sensor heater element has high resistance; O2 sensor heater element has an open circuit; What are the symptoms of code P0135 ? In theory, a failed O2 heater will result in. If you wish to continue running the rear 02 sensor you will need to run another wire from E4 to ground it. The rear O2 is used only for measuring catalytic converter efficiency. The wiring changes above will not enable the ECU to detect when front O2 heater is not functional.. The sensor output goes to the factory Oxygen sensor wire. The heater wires do not have a polarity so one wire should go to ground but not using the same wire as the sensor ground. The other wire should go to the ignition and only have power when the key is in the on position and not when the key is.
Narrowband sensors have between one and four wires. One of the wires will always be the signal voltage. A second wire can be used to isolate the ground end of the signal to reduce signal noise. Three and four wire sensors add a heating element so the sensor starts operating faster and more reliably.. Oxygen Sensor Signal Wire Violet Black Red 5 AMP Fuse 12V Ignition Switch Good Engine mounting Sensor Signal Wire Heater Ground Heater + sensors have 3 or 4 wires, check with vehicle manufacturer, or wiring diagram for your specific vehicle to learn which wire is the signal..
