If the check engine light is on also for the speed sensor, then I would accept this. Refer to Repair Procedures Cell 5 in Electrical Diagnosis. Whether you have 4 wheel drive or 2 wheel drive, the sensor is the closet to the rear drive shaft. Is the resistance within the range specified in the value s column? Truck under drivers seat is the pump and module. Truck under drivers seat is the pump and module.
As a result, oxygen sensors are likely to report fuel mixture problems. If a short to voltage is found in the jumper harness, replace the jumper harness. Failure to carefully and fully inspect wiring and connectors may result in misdiagnosis, causing part replacement with reappearance of the malfunction. You don't need to remove pump just unbolt module from pump. Water can leak into the connector from clogged sunroof drains, A-pillar leaks, or windshield or cowling leaks. We are still getting the above codes and additionally our transmission will shift hard from first to second, but will not shift to third nor will it shift back down now, until we turn the vehicle off.
Unplug it and check for moisture and corrosion. Refer to Repair Procedures Cell 5 in Electrical Diagnosis. There is however a code P0502, which is low input for the vehicle speed sensor. Unplug and remove 10mm bolt, remove. Verify no open or a short to ground is found. You don't need to remove pump just unbolt module from pump. There are three sensors on the transfer case that all looked the same our auto parts store gave us the same sensor for all three.
Sensor Temperature °C Sensor Temperature °F Sensor Resistance Ohms -34 to 4 -30 to 40 2032 to 3107 5 to 43 41 to 110 2417 to 3615 44 to 93 111 to 200 2812 to 4266 The numbers below refer to step numbers on the diagnostic table. Please let us know if you need anything else to get the problem fixed. It's a magnet, any metal shavings? If its autotrac it will be virtually the same thing with an additional speed sensor plug. . If a short to voltage is found in the jumper harness, replace the jumper harness. Is the resistance within the range specified in the value s column? Is it a floor shift, push button, or pb autotrac? Only the front are rotor disk brakes.
Your problem lies in the abs system , possibly the left front sensor, abs ecu or speedo cluster, Clear the code and see if it stay out otherwise you'll need to go to a trusted technician. Disk or drum they should be similar in location. Check the resistance of the rear wheel speed sensor. Refer to Repair Procedures Cell 5 in Electrical Diagnosis. Is physical damage of the jumper harness evident? The following table contains resistance values for the rear wheel speed sensors at varying sensor temperatures for use in diagnosis.
Misfires can be caused by ignition problems, fuel problems or compression problems. They all talk to each other and the computer All generate a refferance voltage. Have big problems with this and probably will come back. If an open or a short to ground is found, repair the circuit. Feb 04, 2016 Apparently it is a speed sensor that is bad. Any guidance would be great, with school starting we really need this vehicle to be safe for our girls.
It should only take around 15 minutes to extract the codes and will immediately identify the suspected circuit. If it is a floor shift or regular push button - look for a single wire loom towards the top center area of the tcase with purple and green wire. Refer to Repair Procedures Cell 5 in Electrical Diagnosis. I have a hunch that it is not seeing any data stream which causes the codes. Inspect all connectors and harnesses for damage that may result in an open or high resistance when connected. Is the resistance within the range specified in the value s column? Module was not common on this vehicle Posted on Nov 21, 2013 I don't think so? Add two teaspoons of salt to twelve ounces of water to make a five percent saltwater solution. It sounds like you have a computer that is out but to be sure you need to connect the car to a scanner that can read live data.
I recommend having someone run a diagnostic test at a shop. Unplug it and check for moisture and corrosion. One more thing is that when I run the car, it would take almost 100 meters before the speedometer work and the transmission start to shift as well. If an open or high resistance is found in the jumper harness, replace the jumper harness. Check the rear of brake at backing plate to see if you can find the sensors.
Sir, the silverado that we have here, the rear brakes are Drum brakes not rotor disk brakes. The last code is for abs system, the codes are all connected. It's possible one of your wheel speed sensors may be either contaminated i. If an open or high resistance is found in the jumper harness, replace the jumper harness. The diagram that you sent to me is rotor disk brake. Posted on Oct 13, 2009 It depends there are 3 speed sensors 1 on each front wheel and 1 on the output shaft of the transmission. Unplug and remove 10mm bolt, remove.
Is the resistance within the range specified in the value s column? The first two codes are for left and right front wheel speed sensors. Refer to Repair Procedures Cell 5 in Electrical Diagnosis. I replaced the vehicle speed sensor but still the same problem. Is the voltage within the range specified in the value s column? C0055 is for rear speed sensor, mounted on top of rear end. We have three codes on our vehicle; c0055, c0300, and p0502 x2. Make sure the wheel speed sensors are connected and clean.
