Is the cam sensor the same as the crank sensor?
It expects the cam sensor to send signal pulses in time with the crankshaft sensor so the proper cylinders get spark and fuel at the correct time. Your cam sensor is in the distributor and changing it does not require a relearn as it is a different style sensor than the crank sensor.
How does the crank sensor work on the ignition module?
When the engine starts to crank, the crankshaft position sensor starts to produce and send its signal to the ignition control module (ICM). The ignition control module upon receiving this AC Volts crank signal, converts it into a DC digital signal and sends it to the ECM.
What is the crank sensor signal on an ICM?
The crank sensor signal is an On/Off type of signal that can be measured with a multimeter or an LED Light. The crank sensor signal is also called the ‘triggering signal’ in this article. As soon as the ICM gets the crank sensor signal, it starts activating the ignition coils sitting atop of it.
Is the crankshaft position sensor reprogramed also?
A dealer is not the only place that can do a re-learn, pretty much any good shop with a bi-directional scan tool can handle it as it is a very common item to be done, even for some diagnostic work. helpful? Is it the same with the cam position sensor also?
When the engine starts to crank, the crankshaft position sensor starts to produce and send its signal to the ignition control module (ICM). The ignition control module upon receiving this AC Volts crank signal, converts it into a DC digital signal and sends it to the ECM.
How does a crankshaft camshaft position sensor work?
Since this type of Sensor only has two wires and no Power Supply, testing them is not that hard: One of the two wires is the Signal wire. Consequently, Sending the Signal to the Fuel Injection Computer or Ignition Module. The other wire acts as a Ground return.
What is the crank sensor on a GM 3.1L engine?
This article will help you test the ignition control module (ICM) and 3X crankshaft position sensor on all of the GM 3.1L and 3.4L overhead valve engines (the 3X crank sensor is also known as the 7X Crank Sensor).
Why does the cam sensor not send a signal to the ignition coil?
Since, the Ignition Control Module really doesn’t send a physical signal (like the Crank or Cam Sensor does to the Switching Device) to the Ignition Coil (s). Why? Well, because the term ‘Switching Signal’ is just a descriptive name for the turning on and off of the primary current passing thru’ the Ignition Coil.
It expects the cam sensor to send signal pulses in time with the crankshaft sensor so the proper cylinders get spark and fuel at the correct time. Your cam sensor is in the distributor and changing it does not require a relearn as it is a different style sensor than the crank sensor.
What happens when you change out the crankshaft sensor?
Someone told me that when you change out your crankshaft position sensor, you have to relearn the car’s brain. And that you have to go to dealership for that. Is this true? have the same problem? The long answer is that the ECM uses the crankshaft signal, along with cam position sensor in order to determine firing of the injection and ignition.
Where is the cam sensor on a valve train?
Your cam sensor is in the distributor and changing it does not require a relearn as it is a different style sensor than the crank sensor. As the timing chain wears and the other valve train parts wear the cam signal can get “out of time” with the crank and you get a P1345 code.
How to set a blanket code for a cam sensor?
The cam sensor needs to be within 10 degrees of crank to by in-sync, otherwise the cam signal isn’t recognized by the PCM. The fleeting nature of a cam sensor sitting right on the fence between in and out of sync would be tough for the PCM to figure out, so it sets a blanket code (P1391).
