O2 Sensor & Wiring Diagrams The O2 or Oxygen sensor is in charge of measuring the content of the exhaust. Learn about the O2 sensor electrical connection and how it relates to the ECM and signal output. Diagnosing O2 Sensor Heater Circuit Failures | MOTOR The O 2 sensor’s heater circuit is controlled in one of two ways. First is the positively controlled type of circuit. If the O 2 sensor heater circuit’s negative wire goes directly to ground, look for a short to power problem. Usually the heater circuit in this case is controlled by a relay. Testing 4 wire oxygen sensors involve checking the heater ... When testing your power supply wire, use a fused jumper wire from battery positive to the oxygen sensor supply wire. When your engine has multiple oxygen sensors, make sure you identify the correct location of the sensor by asking the wiring diagram from ATS. P0141 – Heated oxygen sensor (HO2S) 2, bank 1 heater ...

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. help with o2 sensor wires please | Mustang Forums at StangNet Put 12 volts on the wrong sensor lead and you will ruin the sensor. One white wire is the 12 volts for the O2 sensor heater, the black wire is the signal & heater power ground, one white wire is the O2 sensor output. The sensor wiring is Teflon insulated to survive the high heat around the exhaust system. Heated Oxygen Sensor AutoZone Oxygen Sensor Heater. Specific to: Nissan Altima 2009 2010. The oxygen sensor heater may be tested by performing a resistance test; the sensor must be disconnected from the main engine wiring harness. If the circuit resistance is greater than 5.0 ohms, replace the HO2S.
