Parts for your 2019 Toyota Corolla-Crank angle sensor

2019 Toyota Corolla crank angle sensor — what it does and how to look after it

Yes, the 2019 Toyota Corolla is fitted with a crank angle sensor, more commonly called the crankshaft position (CKP) sensor. This is documented in Toyota’s service literature for the E210 Corolla platform, including the Toyota TIS Repair Manual under Engine/Hybrid System (SFI system – Crankshaft Position Sensor), the Toyota New Car Features (NCF) guide for the 2ZR-FE/2ZR-FXE and M20A-FKS engines (which describes the NE signal from the CKP sensor), and the Toyota Electronic Parts Catalogue, which lists a CKP sensor for 2019 Corolla variants. Those technical sources confirm the part is standard across petrol and hybrid models.

The CKP sensor’s job is to report the crankshaft’s exact position and speed to the engine control module. That real-time signal lets the ECU time spark and fuel precisely, sync with the cam sensor for sequential injection, manage variable valve timing, and monitor for misfire. If the signal goes missing or erratic, the Corolla may be hard to start, run roughly, or not start at all, and will often log a fault like P0335.

There’s no routine replacement schedule for the crank angle sensor on a 2019 Corolla, but it’s smart to give it a once-over during servicing. Under the bonnet, check the sensor connector and loom where it routes down the block near the transmission bellhousing (location varies slightly by engine). Look for chafed wiring, loose clips, oil contamination from nearby seals, or corrosion in the plug. Keeping the area clean and the wiring secure prevents intermittent dropouts that can be a pain to diagnose.

• Common warning signs: extended cranking, random stalling when hot, poor fuel economy, rough idle, or the MIL on with CKP-related codes.
• Good practice: scan for codes, inspect wiring first, then test the sensor signal before replacing parts.

If replacement is required, a quality OE or OE-equivalent sensor is the safest bet. Under the car, the CKP typically sits at the back of the engine reading a toothed reluctor on the crank. Disconnect the battery, unplug the sensor, remove the retaining bolt, and gently twist the sensor free. Fit a new O-ring, lightly oil it, seat the new sensor squarely, and tighten to the workshop manual torque. Clear codes, perform any required idle/ECU learn, and road test. For hybrid 2ZR-FXE models, the CKP is just as critical: even though the engine is spun by MG1 to start, the ECU still needs a clean NE signal to fire and sync reliably.

Does a 2019 Corolla have a crank angle sensor?

It does. Toyota’s 2019 Corolla uses a crankshaft position (CKP) sensor to feed the ECU precise crank angle and speed data for spark, fuel, and VVT control. It’s documented in Toyota’s TIS Repair Manual and New Car Features for both petrol and hybrid engines.

Where is the crank angle sensor on a 2019 Corolla?

It’s mounted on the engine block reading a toothed wheel on the crankshaft, typically at the gearbox/bellhousing side. Access is usually easiest from underneath. Exact orientation differs slightly between the 2ZR and M20A engines, but the principle and placement near the rear of the block are consistent.

When should the CKP sensor be replaced?

There’s no set kilometre interval. Replace it if there are CKP-related fault codes, hard starting, stalling, or confirmed signal issues after wiring checks. Use a quality sensor, renew the O-ring, and follow the workshop manual for torque and relearn procedures.
