One of the settings of the scanner allows you to read the engine speed in revolutions per minute (RPM). This next crank sensor testing technique also uses a diagnostic scan tool. If you want to be proactive, there is some other testing you can do. You might already be experiencing crankshaft sensor problems before the ECU has noted any sign of trouble. Unfortunately, the crankshaft sensor is usually pretty worn by the time that the check engine light is on. This is probably the most straightforward and the most certain way to test for and identify a crankshaft sensor problem. Codes between P0335 and P0338 correspond to crankshaft sensor problems. You can check onboard diagnostic trouble codes with a diagnostic scan tool. If your check engine light is on, then your engine control unit (ECU) has recorded some sort of trouble code. Here is how to test a crankshaft position sensor with or without a code: So before you replace your crankshaft position sensor, you might want to run some tests to determine that the crank sensor really is the source of the problem. However, these same symptoms can be caused by problems with your ignition or fuel injection systems, too. If you are experiencing problems like these, you might need to replace your crankshaft position sensor. There are a number of common symptoms of a bad crankshaft position sensor (CKP) that can help you determine if your sensor has failed, including engine misfires, rough idling, stalling, or hard starting.
