2013 Lexus IS crank-angle sensor: what it does and servicing tips

Yes, the 2013 Lexus IS uses a crank-angle sensor (commonly called a crankshaft position sensor). This is documented in Lexus service literature for the IS (GSE30/35/AVE30 series) where the “Crankshaft Position Sensor (CKP)” is specified and diagnostic trouble codes P0335–P0339 are defined. The Toyota/Lexus Electronic Parts Catalogue also lists a CKP for the 4GR-FSE and 2GR-FSE V6s and the 2AR-FSE hybrid engine, and OBD-II references (SAE J1979) used by this model include CKP-related codes.

On the 2013 IS, the crank-angle sensor feeds the engine control module precise data on crankshaft speed and position so the ECU can time fuel injection and ignition bang on. Without a clean signal, the car can struggle to start, run roughly, or not run at all. It’s absolutely central to smooth idle, decent fuel economy, and proper emissions control.

This sensor isn’t a scheduled service item, it’s typically replaced only if faulty. During regular servicing, it’s smart practice to check for oil contamination at the connector, inspect the harness for rub-through near the front of the engine, and make sure the plug is snug. If faults pop up—hard starting, intermittent stalling, erratic tacho, or a Check Engine Light with P0335/P0336—professional diagnosis with a scope or scan tool live data will confirm if the signal is dropping out.

Replacement is straightforward for a trained tech. Usual steps include battery disconnection, removing any covers for access, unplugging the sensor, swapping the unit, and tightening the retaining bolt to the workshop manual spec. A light smear of clean engine oil on the O-ring helps prevent damage and future leaks. On the V6, access is typically at the front-lower area of the block near the crank pulley, on the hybrid four-cylinder it’s at the timing cover. After refit, clearing codes and confirming stable RPM and cam/crank correlation is standard.

Quality matters here. Genuine or reputable OEM-equivalent sensors maintain the correct signal amplitude and tooth recognition, which keeps the ECU happy. With clean wiring, correct installation, and healthy engine earths, the crank-angle sensor should go the distance without fuss for most owners across Australia and New Zealand.

• Common symptoms: long crank/no start, stalls when warm, rough running, poor fuel economy, CEL with P0335–P0339
• Good practice: inspect wiring and connectors at service time, keep oil leaks in check, use correct torque and O-ring lube on replacement

Popular questions

Where is the crank-angle sensor on a 2013 Lexus IS?
On the V6 models (IS250/IS350), it’s usually mounted low on the engine block near the crank pulley at the front of the engine. On the IS300h hybrid four-cylinder, it’s located at the timing cover. Exact access varies slightly by market trim and engine.

Does the crank-angle sensor need routine replacement?
No. There’s no scheduled interval. It’s replaced only if it fails testing or sets related fault codes. During services, a quick check of the connector and harness routing is wise, especially if there are oil leaks or prior front-end work.

What faults or codes point to a bad sensor?
P0335 and P0336 are the common ones. Owners may also notice hard starting, misfires, or stalling. A technician will verify by checking live data and, if needed, oscilloscope patterns for a clean, consistent crank signal.
