P0336 OBD-II: Crankshaft Position Sensor "A" Circuit Range/Performance
P0336 Severity
Should you fix P0336 yourself?
Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.
Proper diagnosis will save you time and money on unnecessary repairs.
Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.
What causes OBD-II fault code P0336?
The Crankshaft Position Sensor measures the exact rotational speed and position of the crankshaft. This provides a critical data signal used by the Powertrain Control Module (PCM) to control Ignition Spark Timing and Fuel Delivery. This sensor may be built into the distributor on older vehicles. When the PCM detects an irregular signal or no signal, it will set code P0336.
What Does P0336 Code Mean?
OBD-II Code P0336 is defined as a Crankshaft Position Sensor "A" Circuit Range/Performance
The Distributor/Crankshaft Position Sensor measures the exact rotational speed and position of the crankshaft. This provides a critical data signal used by the Powertrain Control Module (PCM) to control Ignition Spark Timing and Fuel Delivery. When this signal is interrupted for any reason, code P0336 is set and the MIL or Check Engine Light is illuminated.
P0336 Symptoms
- Check Engine Light will illuminate
- Hard starting/cranking without starting
- Engine hesitation or stalling
- Engine dies and will not re-start
- In many cases, no abnormal symptoms may be noticed
Common Problems That Trigger the P0336 Code
- Defective Crankshaft Position Sensor
- Faulty or corroded Crankshaft Position Sensor wiring or connections
- Defective Camshaft Position Sensor
- Rough running/misfiring Engine
Common Misdiagnoses
- Crankshaft Position Sensor is replaced when the cause is a defective Camshaft Position Sensor
- Crankshaft Position Sensor is replaced when the cause is a poor connection or chafed wiring
- Crankshaft Position Sensor is replaced when the cause is a misfiring engine
