Summary
  • Diagnostic trouble code (DTC) P0336 stands for “Crankshaft Position Sensor A Circuit Range/Performance.” It’s set when the powertrain control module (PCM) receives a signal from the crankshaft position sensor that deviates from specification.
  • Possible causes of the P0336 code include a defective crankshaft position sensor, reluctor ring issues, and crankshaft position sensor connector issues.
  • Some symptoms of the P0336 code include an illuminated check engine light, a hard starting/cranking engine, and hesitation during acceleration or stalls.

The crankshaft position sensor measures the rotational speed and position of the crankshaft. The variable reluctance type CKP sensor does this by detecting the magnetic flux changes between the peaks and valleys of a “reluctor wheel” on the crankshaft.

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 will 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.

Code P0336 may be set when the PCM receives a signal from the crankshaft position sensor that deviates from specification.

For example, on a 2015 Chevrolet Camaro the P0336 sets under the following conditions:

  • Condition 1: The ECM detects that 10 or more crankshaft resynchronizations have occurred within 10 seconds.
  • Condition 2: The ECM does not detect the synchronization gap on the reluctor wheel for greater than 0.4 seconds.
  • Condition 3: The ECM does not detect the synchronization gap on the reluctor wheel for 1.5 seconds after the starter was engaged.
  • Condition 4: The ECM detects less than 51 or greater than 65 crankshaft position sensor pulses during 1 engine revolution for 8 out of 10 engine revolutions.

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.

This video may also give you an idea of what the troubleshooting process for the P0336 code might involve:

If you’re not comfortable addressing the issue, it’s best to leave the job to the professionals and go to an auto repair shop for an accurate diagnosis.

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.

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

A Closer Look at the Variable Reluctance Type CKP sensor

The variable reluctance sensor (VRS) sensor is basically a fine wire coil wrapped around a magnet, and the tip of the magnet is near the crank sensor trigger wheel teeth. This will be a 36-tooth wheel with one tooth missing; this is called a “36 minus 1.” There are 10 degrees of angle between each of the regular teeth. Thus, this is often called the “crank angle sensor.”

Any time a tooth on the reluctor wheel passes the tip of the magnet, it creates a magnetic wave that is output from the sensor terminals. It’s this wave that the ECM/PCM is using to determine how often to fire the injectors and when to fire the ignition coils.

The faster these reluctor teeth pass the magnet’s tip as the engine speeds up, the higher the voltage and frequency of the signal. That means the wave will be taller and the waves will be closer together in time. That’s always the way magnetic sensors work, regardless of whether they’re reading the speed of a wheel (as with ABS), a transmission shaft, or the crankshaft.

The missing tooth on the crankshaft reluctor wheel causes the CKP sensor to create a larger wave at that one point and enables the ECM/PCM to  identify the crankshaft’s position.The other kind of crankshaft position sensor is a Hall-Effect unit that produces a square wave signal. The trigger wheel is the same, but the signal is different. Hall-Effect sensors can have either two or three wires, depending on the design of the sensor. This kind of sensor is just as common as the VRS type sensor – even more so on later model vehicles.

Where To Buy Parts for the P0016 Code

An engine suffering from the symptoms of the P0016 trouble code will be unreliable and difficult to work with. These symptoms might even lead to your vehicle being utterly unusable. Addressing the problems causing the code can be a bit of a hassle though, as there are many parts you might need. Thankfully, whether it’s a new timing chain, reluctor ring, or camshaft sensor that you need, you can trust CarParts.com.
