What makes the p0337 crankshaft position sensor low input?
If ECU cannot detect enough voltage coming from the CKP sensor, it sets DTC P0337 Crankshaft Position Sensor “A” Circuit Low Input. What are the common causes of code P0337 ?
Why do I have p0337 stored in my PCM?
Although generic, the specific repair steps may vary depending on make/model. When I have diagnosed a stored code P0337 (in the past) it was because the powertrain control module (PCM) had detected a low input voltage signal from the crankshaft position (CKP) sensor circuit.
How is the crankshaft position sensor used in an engine?
The Crankshaft position sensor also known as the crank position sensor is an electronic device used in an engine to record the rate at which the crankshaft is spinning. This information is used by the Electronic Control Module ( ECM) to control ignition and fuel injection.
What is the CKP sensor for a crankshaft?

Why does my car keep setting the p0339 code?
A number of potential causes may lead to the P0339 code being set in the car’s computer, including the following: Damaged crankshaft position sensor. Damage to the sensor’s connectors. Damage to the sensor’s wiring harness.
What does the code p0335 on OBD-II mean?
What Does the Code P0335 Mean? This is a fairly common question among vehicle owners who own a car with an OBD-II equipped vehicle. Essentially, this code refers to an issue in the crankshaft location or its relays. The crankshaft position sensor is a stationary piece, but it works with the reluctor ring to determine positioning and voltage.
What causes no pulse on crankshaft position sensor?
If there is a +5 V reference and you still see no pulse while cranking, the most likely cause is a defective sensor, though this doesn’t rule out a mechanical problem, such as a broken reluctor wheel. Magnetic – The magnetic sensor generates an analogue signal, that is, a signal that switches positive to negative.
How can I check the crankshaft position sensor?
So, take a multimeter, set it to measure AC voltage, connect the red and black multimeter leads to the sensor’s signal and ground pins, and crank the starter motor. You should see an AC signal on the multimeter. If your meter has a “Hz” button, you should be able to read the frequency of the signal.

Where does GMIS 24-pulse crankshaft signal come from?
GMís 24-pulse crankshaft signal is a series of long (12 degrees) and short (3 degrees) pulses that are 15 degrees apart. This 24x pattern is generated from a crankshaft reluctor mounted on an engineís crankshaft and through a CKP sensor. GMís 24x crankshaft reluctors feature two rows of teeth that are out of phase.
What are fault codes related to the crankshaft position sensor?
Fault codes related to the crankshaft position sensor are: P0335 Crankshaft Postion Sensor A Circuit Malfunction P0336 Crankshaft Position Sensor A Circuit Range / Performance P0337 Crankshaft Position Sensor A Circuit Low Input P0338 Cranshaft Position Sensor A Circuit High Input P0339 Crankshaft Position Sensor A Circuit Intermittent
How much does it cost to diagnose a p0337 code?
The cost to diagnose the P0337 code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
When is the p0337 code detected in an engine?

Why is my DTC p0337 CKP sensor dead?
DTC P0337 may have number of causes. Here are some of the most common. Dead CKP Sensor – Because the sensor is typically not a high-price item, some suggest “just replacing” the sensor as a matter of course. We always suggest fully diagnosing the system before condemning the sensor.
