TESTING

This sensor produces an A/C voltage signal based on information gathered while the engine is running. Testing the CMP sensor requires several special tools that are very expensive to purchase. Due to this fact, we have determined testing this sensor to be beyond the scope of the do-it-yourself mechanic. The sensor can be monitored with an appropriate scan tool using a data display or other data stream information. Follow the instructions included with the scan tool for information on accessing the data.
