The crankshaft position sensor is one of the most critical devices for engine management. It measures the rotational speed and position of the crankshaft. The sensor does this by detecting the magnetic flux changes between the peaks and valleys of a reluctor wheel on the crankshaft.
The sensor produces pulsed voltage signals every time a tooth passes the sensor. The powertrain control module (PCM) uses this information to sequence ignition timing and (in some cases) fuel delivery, detect cylinder misfire, and control the camshaft position actuator (if equipped). An interruption to this signal may set off the P0336 code.
What Does the P0336 Code Mean?
Diagnostic trouble code (DTC) P0336 stands for “Crankshaft Position Sensor “A” Circuit Range/Performance.”
This engine code is set when the PCM receives a signal from the crankshaft position sensor that deviates from specification.
Note: The definition of code P0336 may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition.
Vehicles that are prone to code p0336 include various models of Chevrolet (especially Chevy Malibu), Honda, Dodge, Nissan, and Hyundai.
What are the Possible Causes of the P0336 Code?
- Defective crankshaft position sensor
- Reluctor ring issues (e.g., broken, loose, dislodged, improperly installed, etc.)
- Crankshaft position sensor connector issues (e.g., corroded, moist, damaged, etc.)
- Crankshaft position sensor circuit issues (e.g., damaged wiring, loose connections, or electromagnetic interference, etc.)
- Defective camshaft position sensor
- Disrupted signal between the sensor and reluctor wheel
- PCM issues (software update needed)
What are the Common Symptoms of the P0336 Code?
- Check engine light is illuminated
- Hard starting/cranking engine
- Hesitation during acceleration or stalls
- Engine misfires in one or more cylinders
- Engine dies and won’t restart
- Reduced gas mileage
How to Diagnose the P0336 Code
Testing a crankshaft position sensor requires technical automotive knowledge that most drivers may not have. At the same time, the steps for repair and diagnosis of the P0193 code tend to vary depending on a vehicle’s year, make, and model. For instance, the confirmed fixes for a P0336 in Chevy are likely not the same as the solutions for a P0336 in Jeep.

How to Fix the P0336 Code
In some cases, the removal and programming of a crankshaft position sensor require special tools that you may not have in your garage. If you want to spare yourself the trouble of figuring these things out yourself, get your vehicle checked by a licensed mechanic instead.
If you are an advanced DIYer with extensive auto repair knowledge, you may refer to the applicable repair manual for your car or get an ALLDATA single-vehicle subscription to search for vehicle-specific repair information.
Other Notes About P0336
The P0336 code belongs to a range of crankshaft position sensor codes that are triggered by a malfunction in the sensor/circuit:
- P0335 Crankshaft Position Sensor A Circuit Malfunction
- P0337 Crankshaft Position Sensor A Circuit Low Input
- P0338 Crankshaft Position Sensor A Circuit High Input
- P0339 Crankshaft Position Sensor A Circuit Intermittent
