Crank Sensor Voltage Low
Crank Sensor Voltage Low. If no signal comes out of the sensor, most likely the sensor is bad. Excessive gaps between the sensor and pulse wheel;
Turn the ignition off and plug back in the ckp sensor to the harness connector. The sensors internal circuitry detects this and produces a signal which the pcm reads. If your reference voltage is lower than expected or zero, check the wire and connector for damage, or a loose terminal.
This Can Happen For Multiple Reasons And A Mechanic Needs To Diagnose The Specific Cause For This Code To Be Triggered In Your Situation.
You have to watch the multi meter while someone cranks it. Reduced sensor output due to excessive dirt and detritus on the sensor housing or pulse wheel. This voltage is very low;
Damage To The Sensor Housing Or Pulse Wheel;
The change in the magnetic field cause the voltage from the sensor to change. If a car stalls intermittently, monitoring the sensor signal can provide the answer: The cmp sensor works in conjunction with a 1x reluctor wheel on the camshaft.
Remove The Sensor And Inspect It For Signs Of Physical Damage Or Contamination.
If it has 12 volts but his should be done in voltage a/c not dc. The camshaft sensor works according to the hall principle. The battery voltage is usually around 12.9 with the engine off and the fan and water pump running.
If You Are Getting This Then The Crankshaft Sensor Is Not The Problem.
Turn ignition on with engine off. If necessary, check your car's computer. P0338 ckp sensor circuit high frequency code.
You Can Also Check The Resistance Of The Sensor By Putting The Digital Multimeter Knob To The Ohm Scale And Connecting Both Leads Of The Digital Multimeter To The Crank Sensor Wires.
Crankshaft position sensor supply voltage too low 1. I checked the voltage between the re or pink and the black, 12,34v. Our certified mobile mechanics can come to your home or office to perform the check engine light diagnostic for.
