Wells Nissan P0507 Relearn Cam and Crank Sensor location and Testing

http://www.wellsve.com/ This video will locate and test the cam and crank sensor on a 2004 Nissan. It will also demonstrate an alternative method to relearn the idle air control. When a P0507 or a high idle occurs after a throttle body clean, the TSB requires the use of the factory (Consultant II) scan tool to reset idle air control. The reset can also be performed by following the steps in this video, without a scan tool.

Camshaft Position Sensor P0340 Testing and Replacement HD
Click Here to Subscribe! http://youtube.com/carsntoys Website: http://carsntoys.net Today we're testing the camshaft position sensor, along with its harness connector. The sensor consists of a permanent magnet, core and coil. When the engine is running, the gap between the sensor and cam sprocket will periodically change. This generates a voltage and sends the information to the ECM. Code P0340 could be generated by the following reasons: - Harness or connectors is open or shorted. - Camshaft position sensor - Starter motor / starting system circuit. Tools Used: Safety Glasses 10mm wrench Digital Multimeter (DMM) Starter Replacement Video: http://youtu.be/q8n9OZfwKrM Note: This video is being performed by an experienced tech.

P0014 / P0306 2002 Trailblazer Wells Vehicle Electronics
http://www.wellsve.com When we first drove this vehicle into the shop it felt like it had multiple cylinders misfiring. We checked it with the scan tool and sure enough there were lots of history misfires. Even though it also had a solid misfire on number six we decided to correct the multiple misfires first. We started the diagnosis by repairing the P0014 VVT code first. With the thought in mind that this correction might repair all the misfires. Sit back and enjoy as we take you step by step through the diagnostic process.





Crankshaft Position Sensor REF P1335 Testing and Replacement HD
Click Here to Subscribe! http://youtube.com/carsntoys Website: http://carsntoys.net In this episode we'll be testing the Crankshaft Position Sensor REF (reference) - trouble code P1335. This sensor detects the Top Dead Center 120 degrees signal. The sensor consists of a permanent magnet, core and coil. When the engine is running, the gap between the sensor and the crankshaft pulley will periodically change. This change causes voltage signal in the sensor coil to change. The ECM receives the voltage and detects the TDC 120 degrees signal. Code P1335 is caused by the following: - 120 degrees signal is not entered to the ECM during engine running. - 120 degrees signal is not entered to the ECM for the first few seconds during engine cranking. - 120 degrees signal cycle excessively changes during engine running. Areas to look at: - Crankshaft position sensor harness connector - Crankshaft position sensor - Starter motor and/or starting system. As stated in the video, use Google Images, Google web search along with car specific websites to find diagrams, ohms/resistance readings, etc. for your specific vehicle.
