What kind of signal does the ignition module need?
OK, moving on along… for the ignition module to create this Switching signal, it needs to receive a C ran k shaft P osition (CKP) sensor signal (this signal is usually referred to as the Triggering signal and in GM service literature it’s known as the 3X or 7X CKP signal).
How does the crank sensor control the ignition module?
The ignition module starts to turn On and Off the ignition coils in their proper firing order to create spark, after the crank signal arrives. This On/Off action is the Switching signal referred to above. Under 400 RPM’s, the ignition control module controls spark timing without the help of the fuel injection computer.
Where is the CKP sensor located on a GM 3.1 V6?
The CKP sensor is located on the engine block (the side that faces the transmission) and goes thru’ the engine block itself. Late 3.1L and 3.4L V6 engines use 2 crankshaft position sensors. One is located behind the crankshaft pulley on the front of the engine and the other is the same one described…
How to diagnose no spark no start Chrysler?
This article will help you to troubleshoot and diagnose a No Spark No Start, or a misfire condition on your Chrysler, Dodge, or Plymouth 3.0L V6 equipped car or mini-van. You DO NOT need a scan tool to take advantage of the step by step diagnostic instructions in this article.
Can a PCM not activate the ASD relay?
Without these two signals, the PCM will not activate the ASD Relay. Also, with the signals from the crankshaft (and camshaft) position sensor assembly, the PCM starts to activate the ignition coil to start sparking away.
What does the crank sensor on a Chrysler do?
This on/off action will henceforth be called the Switching signal. The crank sensor is at the heart of this type ignition system. here are some useful facts that you should be aware of about the crank sensor on your Chrysler (or Dodge or Plymouth) vehicle:
What does the PCM do for the ignition coil?
With these two signals, the PCM activates the Auto Shutdown (ASD) Relay to feed power to pretty much every electronic component under the hood, especially the ignition coil. Without these two signals, the PCM will not activate the ASD Relay.
