Otherwise, the boot might melt and it might prevent the sensor from operating correctly. Do not drop a sensor or handle it roughly.Į) Make sure that the silicone boot on the sensor is installed in the correct position. The oxygen sensor replacement is a 15128 and has a really t.

Damaging or removing the pigtail or electrical connector will render the sensor useless.ī) Keep grease, dirt and other contaminants away from the electrical connector and the louvered end of the sensor.Ĭ) Do not use cleaning solvents of any kind on an oxygen sensor.ĭ) Oxygen sensors are extremely delicate. Replacing an oxygen sensor on a GMC Terrain or Equinox is easy when you know what tools you need. This code is triggered by the first downstream (front) O2 sensor. Be careful not to burn yourself during the following procedure.īe particularly careful when servicing an oxygen sensor and follow these guidelines:Ī) Oxygen sensors have a permanently attached pigtail and an electrical connector that cannot be removed. Rather than risk damage to the sensor or its mounting threads, start and run the engine for a minute or two, then shut it off. Note: Because it is installed in the exhaust manifold or pipe, both of which contract when cool, an oxygen sensor might be very difficult to loosen when the engine is cold. One is located before the catalytic converter and one is located just after the catalytic converter. There is no set time when O2 sensor should be replaced, but 100,000 miles or 5 years is a good guideline, or when the check engine light indicates a fault.

The oxygen (O2) sensor informs the engine computer how much free oxygen is in the exhaust, allowing it to judge exactly how much fuel to provide for best power, economy, and emissions.

If the voltage signal is negative, the multimeter probes have been connected in the opposite sense, so the negative probe is connected to the signal wire, while the positive probe is connected to earth.All Haynes Digital Online Manuals feature everything you love about our books in an instantly accessible digital online form, that you can use via any device with an internet connection. If the voltage signal is positive, this indicates that the positive multimeter probe is connected to the signal wire and negative probe is connected to earth. Within a minute, the sensor should register a voltage in the 0-1 V range. Heat up the sensor's tip with the premix flame. To test, set the multimeter to voltage mode and attach its probes to the two non-heater wires, noting which probe is negative and which is positive. However, this does require the sensor to be heated up to operating temperature. The O2 sensor signal gives an indication of oxygen content sensed by the probe by sending an induced voltage that corresponds to the level of oxygen detected. Note down which two wires correspond to the heater circuit and proceed to Test 2. The two wires which register a resistance reading are the heater wires the other two will show up as an open circuit or infinite resistance.Īs the O2 heater is resistor-based, polarity is not a concern here. To test, set the multimeter to resistance mode and use it to probe and figure out which wires register a resistance (usually 4-6 Ω). These wires serve to heat up the O2 sensor to bring it up to operating temperature via a resistance-based heating element. With nothing more than a decent multimeter and premix flame (blowtorch or gas stove), a two-test sequence can reveal the identity of each wire, assuming the O2 sensor is fully-functional: No, you don't have to rely on wire colors to figure out what's what.
