Troubleshooting Tips for the Toyora Supra Crankshaft Position Sensor
Your Toyota Supra's crankshaft position sensors are extremely important in modern cars, as they are needed for the whole ignition process of the vehicle. It is responsible in determining the RPM and position of the crank so that the timing of ignition and fuel injection will be precise. Over time, however, this car part will wear down just like any other part. If this happens, then the whole ignition process is in trouble. If your want to keep your Toyota Supra running and ready, then start doing some troubleshooting for the common problems the parts of your vehicle may have.
One of the most common effects of a bad crankshaft position sensor is when you can't get the engine to start. Since there is no signal being given to the powertrain control module (PCM) to create a spark and inject fuel, ignition will not occur. You could also acquire a Noid Light to check if the fuel injector pulses are being given. These devices help determine various ignition problems, and are very easy to build inside your own garage. Upon using it, if you did not see any injector pulses given, then the problem is most likely another car part; otherwise, you might need to get another crankshaft position sensor.
The other great way to tell if the crankshaft position sensor has gone bad is by looking at your dashboard and seeing the "check engine" light go up. This is problematic since even if you manage to start the car up, a badly damaged crankshaft position sensor could shut it down very suddenly and without warning. To check if it is functioning correctly, take a multimeter. Use that device by connecting it to the number 1 and number 2 wires of the crankshaft position sensor. Then, ask a friend to crank up your engine so that you will be able to read the volts reading easily. As for the values, they should move around between .5 volts to 1 volt constantly. If it does not do that, then there is something wrong with your crankshaft position sensor and it must be replaced as soon as possible.
A Handy Maintenance Guide for Your Toyota Supra Crankshaft Position Sensor
In your Toyota Supra, the crankshaft position sensor plays an important role in your car ignition system. Like a war messenger, its task is to send the message of the crankshaft's position, as well as its position, to the other areas of the ignition system. In the unfortunate event that the part breaks down, the connection would be lost, and the entire starting-up process of your vehicle would discontinue. If you want to keep your crankshaft position sensor ready to rock all the time, then always do some regular maintenance. Here are some tips to help you retain the part's functionality as long as possible:
Clean the crankshaft position sensor thoroughly.
A very easy way to ensure the longevity of your Toyora Supra's crankshaft position exterior is by simply cleaning it. Some people do not realize the importance of a car part that is free and dust and other sorts of debris, especially with the crankshaft position sensor. If a deposit of dust and debris is allowed to form, it will not be able to signal the timings properly and ignition problems will occur.
Carefully remove the wiring harness connector of the sensor before you take out the sensor itself. Then, remove the bolts holding the sensor in place to give you full access to the part itself. Lastly, take a rag and clean off anything that seems to dirty up the part. If you think it is too dirty, then there might be something else that is problematic and needs checking. The culprit is usually a leak from another area of the vehicle spilling onto the crankshaft position sensor.
Check the voltages of the crankshaft position sensor.
The other way to keep the crankshaft position sensor working properly via multimeter. This tool is very important to the DIYer as it allows you to measure voltages and read various electrical data from your vehicle. When doing your regular maintenance, always remember to measure the voltage of the crankshaft position sensor. The value must always be consistent in between .5 to 1. Any value below or above would indicate that the part needs further inspection.
