There could be numerous other things that can interfere with a test. If voltage is about 5 volts, go to next step. Other than a Check Engine Light and an inaccurate speedometer, there should be next to no symptoms associated with this trouble code. They just let you know that while performing a test that test either failed or could not be completed with a good result. Took me 6 hours to complete and did not fix the input speed sensor problem. Short Term fuel trim values change rapidly in response to changes in the oxygen sensor signals. Does the resistance measure greater the specified value? Check out the video to see how to change this sensor.
These are not to difficult to change. I don't remember specifically for your vehicle. Enter the 5 character trouble codes in the search box and submit the search. No there is no cost for the help just if you are able to with your information and I will email it back to you. Jan 23, 2014 The engine and the automatic transmission transmission control is only for automatics, engine is still computer controlled no matter the transmission type in this vehicle are computer controlled and in most cases when a fault occurs a fault code is stored in the memory of the computer control module. When the check engine light comes Buick Rendezvous P0502 code on the first you should check is the gas cap. Pull over, retighten it, and take a look at the cap to see if it has any cracks in it.
Start and operate engine at idle. This causes the ignition coil to provide a spark and the injector to inject fuel into each cylinder at the right time. Did you find and correct the condition? The condition could be caused by an intermittent connection in the Input Speed Sensor circuit. Did you find and correct the condition? Next, a road test will be performed to confirm the problem is present. After replacing sensor, go to step 14. After this signal is converted into a more precise rectangular waveform by the waveform shaping circuit inside the combination meter, it is then transmitted to the.
I would suggest monitoring the sensor with a higher end scan tool capable of reading transmission data. Is it inside the transmission? Oct 05, 2014 After doing a little research I own a couple of pretty decent scanning tools and have become familiar with how they function Without knowing the actual code for the error there is no way of telling exactly what it's showing as the error. Jul 13, 2011 If it is a service light it may be as simple as having some of the basic services performed like an oil change. Pay particular attention to the 20-pin connector to make sure it is not stretched tightly. A check of the suspension on all four wheels would be performed to check the tone rings and wheel speed sensors. Have I found the problem? Does the voltage measure greater than the specified value? First check your fuse and then check and make sure your getting 12 volts to the terminal at the blower, You could have a blown fuse, a bad switch, or a bad resister , if your getting voltage to blower motor then most likely it will be the motor. The plastic on the bottom of the air box is sharp and over time cut through the tape covering the loom and cut into the wires leading to the transmission.
Make sure the terminals are fully seated in the connector. Now don't ask yourself; What should you do with P0502 code? If it is a check engine light or fault light, you will need to get the vehicle scanned for codes that may have been set. How serious is the P0500 code? On rear wheel drive vehicles the speed sensor may be found on the output shaft of the transmission or located within the rear differential. Not sure how mechanical you are but I will be happy to give you all the tests that need to be done in order to narrow down either the componant or wire that is causing the problem. If you are a Buick Rendezvous owner, you may have encountered an acceleration issue when you put your foot down for a pass or from a stop.
I just used butt connectors to rejoin the wires and the Rendesvous was fine for another year. A change in scan tool display indicates fault location. The transmission can have mechanical issues as well such as no gear engagement at all or a failed pump or other pressure related problems. If either sensor isn't working correctly, the car will run rough and the engine will be less efficient. Remember, a fault code is only a place to start looking for a problem, it does not necessarily give you a correct diagnosis of the underlying probem Oct 27, 2010. If no problems are found, go to next step. Does it start and run ok? Daggum I should have updated this thread, forgot I'd posted it.
Need help with a P0500 code? P0500 will not prevent the vehicle from operating but it may shift roughly causing some discomfort when driving. Do not automatically assume that the input speed sensor is faulty. Refer to in Wiring Systems. If you think you would be able to do it with step by step instructions, feel free to email me at with all of your information. All you need to do is take the old one off and screw on the new one. What needs to be done is have the dealer or a well equipped shop run a fault code test and do the diagnostics associated with the code or codes.
If you've already made it to the store, you might as well just replace it. Check for proper clearance between the connector and other components. You need to fix the problem that is causing the light to come on. Check for plugged intake air duct or dirty air filter. Turn ignition on, engine off. If test light illuminates, go to step 8.
