Cam shaft torque specs 2010 3.0 liter equinox JA: Our Chevy Mechanic will be able to provide you with the specific camshaft torque read more. 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. Cam shaft torque specs 2010 3.0 liter equinox. 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.

Follow my Builds / Projects: Quick video on how to change. Within a minute, the sensor should register a voltage in the 0-1 V range. How to replace Upstream or Primary o2 sensor on 2010 to 2017 Chevy Equinox with 2.4 P0153 Code. 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. X-ray diffraction was obtained using an INEL EQUINOX 2000 model with a. 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. in surface chemistry, and high chemical and thermal stability (Xia, 2011). 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: After the new ones are installed clear all codes before starting engine. Use a 6 point socket so the old one doesnt round the edges. They make special O2 sensor sockets that are 7/8 in or 22.2 mm, I would consider getting one, a good one is not expensive.

Oxygen sensors (Air fuel ratio sensors) are a common problem on many vehicles. The hardest part is getting the old ones to break free and thread out.

Thanks for the replies, it always help to sound thing out.No, you don't have to rely on wire colors to figure out what's what. A P1155 or P1135 code indicates you have a bad sensor. I'm thinking that everything will fall into place when I have the probes on the sensors floating ground instead of chassis ground. I am now going to take the readings with the scope with the engine running and compare to the live data on the scanner. This is usually within the operating range of the sensor’s heater. Since I am taking the readings directly at the sensor, I am thinking that this may be a slight voltage drop in the harness between the ECM and the sensor. You connect the light to the vehicle’s O 2 sensor heater harness in place of the sensor. Of course the scanner is still showing 1.9 volts. These readings appear to be inline with the specs in the manual.
PPL\WHT High Reference to Tan\WHT Low Reference = 1.80 volts. Tan\WHT Low Reference to chassis ground = 1.04 volts PPL\WHT High Reference to chassis ground = 2.78 volts HO2S ( heated oxygen sensor and different operation to O2 sensors) are located in the exhaust manifold before the cat converter. With engine cold, key on, engine off I took readings at the sensor with DVOM. I got a little confused with the connections between the sensor's floating ground controlled by the ECM and the chassis ground.
Ok, things are starting to come together and make a little more sense.
