P0336 on Toyota by model: symptoms, diagnosis and fix
The crankshaft position sensor (near the bellhousing/starter, PN 90919-05030 on 2ZR-FE cars) degrades on high-mileage Corollas, sending an erratic or lost signal to the ECU. This causes intermittent stalling, hard or no-start conditions and sets P0335 'Crankshaft Position Sensor A Circuit Malfunction' (or P0336/P0339). Symptoms are often heat-related and intermittent, making it a frequently searched no-start cause.
Common Symptoms
- Intermittent stalling
- Hard start or no-start (often when hot)
- Check engine light with P0335
- Erratic tachometer during the fault
How to Fix
Diagnose the P0335 by checking the sensor wiring/connector and the sensor's signal (resistance and waveform) before replacing, as a chafed harness or corroded connector can mimic a bad sensor. Replace the crankshaft position sensor with an OEM/Denso unit (owners report aftermarket sensors re-throwing the code); PN 90919-05030 for 2ZR-FE (confirm exact PN for 1ZZ-FE by VIN). Clear codes and verify start/idle after repair.

Frequently asked questions
What does P0336 mean on a Toyota?
P0336 stands for "Crankshaft Position Sensor 'A' Circuit Range/Performance." P0336 means the engine control module detected a crankshaft position sensor signal that is present but outside the expected range or pattern — for example, intermittent dropouts, an erratic waveform, or extra/missing pulses. The crankshaft position sensor tells the computer the exact position and speed of the crankshaft, which is essential for timing fuel injection and ignition. When this signal is unreliable, the engine may stumble, stall, hesitate, or be hard to start. Because it underpins basic engine operation, this code should be addressed promptly. On Toyota it is documented across 1 model: Corolla.
What are the most common causes of P0336?
The most common causes of P0336 are: Failing crankshaft position sensor, Damaged or contaminated reluctor/tone ring (debris, missing teeth), Wiring damage, chafing, or corroded connectors, Incorrect air gap or loose sensor mounting, Electrical interference from nearby high-voltage components, Metal shavings on the sensor tip, ECM/PCM fault (less common). The specific cause varies by vehicle.
How much does it cost to fix P0336 on a Toyota?
Published repair estimates on Toyota range from $120 to $350 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
