2016 Lexus IS crank-angle sensor: what it does and how to look after it

Based on Toyota/Lexus technical sources, the 2016 Lexus IS does use a crank-angle sensor (commonly called a crankshaft position sensor or CKP). The Lexus Technical Information System (TIS) repair manuals for the 8AR‑FTS (IS 200t) and 2GR‑FSE/2GR‑FKS (IS 300/IS 350) engines describe the CKP as providing the “NE” signal to the engine control module. The Electrical Wiring Diagram and the factory diagnostic sections for DTCs P0335–P0339 also list this sensor as standard equipment on these models.

On a 2016 Lexus IS, the crank-angle sensor’s job is to tell the ECU exactly where the crankshaft is and how fast it’s spinning. With that timing info, the ECU can sync fuel injection and spark perfectly, which is how the car gets smooth idle, crisp throttle response, and proper emissions. If the sensor goes out of range or fails, the ECU can’t accurately time combustion—so you may see a no-start, sudden stalling, rough running, or the rev counter dropping out. The check engine light usually joins in with a P0335-type code.

It’s not a routine service item like oil or filters, but it’s worth a look whenever there’s an intermittent stall, extended cranking, or misfire that diagnostics can’t easily pin on coils or injectors. Visual checks under the bonnet help: make sure the CKP connector is clean, the wiring isn’t chafed near the crank pulley or along the block, and there are no oil leaks wicking into the plug.

Replacement is straightforward for a qualified tech. The basics: disconnect the battery, unplug the sensor, remove the retaining bolt, and swap in a genuine-quality sensor with a fresh O‑ring. Lightly oil the O‑ring, seat the sensor squarely, route the loom as per the factory path, and tighten to the specified torque from the service manual. After refitting, clear codes and let the ECU relearn idle. If the engine still cranks long or stalls, confirm cam and crank signals with a scope and check for timing chain/belt alignment concerns.

Pro tips for longer life:

• Keep the connector dry and locked, don’t pressure-wash directly at the front of the engine.
• Fix any front main seal or timing cover seepage that could contaminate the sensor.
• If codes P0335–P0339 appear, test wiring continuity and sensor output before replacing parts.

Popular questions about the 2016 Lexus IS crank-angle sensor

Where is the crank-angle sensor on a 2016 Lexus IS?
On the 8AR‑FTS 2.0L turbo (IS 200t), it’s typically mounted low on the front of the engine near the crank pulley/harmonic balancer. On the 2GR V6 (IS 300/IS 350), it’s usually positioned at the lower block, reading a trigger wheel on the crank. Access may be from underneath with the undertray off.

What symptoms point to a failing crank-angle sensor?
Common signs include hard starting or no-start when hot, random stalling at idle or when coming to a stop, rough running with sudden RPM drops, and a check engine light with codes like P0335. If the tachometer intermittently dies while the engine runs rough, that’s another handy clue.

Is it safe to keep driving with a dodgy crank-angle sensor?
Not ideal. A sensor that’s on the way out can cause the engine to stall without warning, which isn’t great in traffic or on the motorway. It’s best to scan it, confirm the fault, and sort the repair promptly to avoid a no-start situation.
