Can a camshaft position sensor cause no spark?
If the camshaft position sensor is malfunctioning, the computer may not be able to determine the correct time to fire the ignition coils, and there may end up being no spark.
Will a bad crankshaft position sensor cause no spark?
A bad Crankshaft Position sensor is a common cause of no starts. The signal from this sensor goes to the PCM or ignition module that switches the ignition coil(s) on and off. In ignition systems with a single coil and distributor, a bad coil or a cracked distributor cap or rotor can prevent the spark plugs from firing.
Does crankshaft position sensor prevent spark?
In A Nutshell, The Crankshaft Position Sensors Job Is To Help: The Ignition System produce a Spark.
What happens when a camshaft sensor goes bad?
A failing camshaft position sensor (CMP sensor) can produce a confusing range of problems, depending on the way it fails and the model of the car: On some vehicles, a failing camshaft sensor may lock the transmission in a single gear until you turn off and restart the engine.
How to test no spark no start test?
No spark from all of the Coil-On-Plug Ignition Coils. No fuel injector pulses from the fuel injector connectors as tested using a Noid Light. P0335: No Crank Sensor Signal Detected. P0336: Inconsistent Crank Sensor Signal Detected.
What does no start on crank sensor mean?
P0335: No Crank Sensor Signal Detected. P0336: Inconsistent Crank Sensor Signal Detected. The thing to remember about having a failed crank sensor, is that if you have spark or fuel injector pulses, the crank sensor is OK and not the cause of your No Start Condition.
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.
