Parts for your 2020 Lexus Is-Crank angle sensor

2020 Lexus IS crank-angle sensor (crankshaft position sensor)

Yes, the 2020 Lexus IS uses a crank-angle sensor—more commonly called the crankshaft position (CKP) sensor. This is confirmed in Lexus service literature for the 8AR‑FTS (2.0‑litre turbo) and 2GR‑FKS/FSE (3.5‑litre V6) engines in the 2020 IS range, the Lexus parts catalogue listing a Crankshaft Position Sensor for these engines, and the applicable OBD‑II diagnostics (e.g., DTC P0335 series) documented in the Lexus Technical Information System (TIS) repair manuals.

On this model, the crank-angle sensor sits at the engine block/timing cover adjacent to the crankshaft. It reads a toothed reluctor to tell the engine control module exactly where the crank is and how fast it’s spinning. That info is the heartbeat for spark timing, fuel injection sequencing (including D‑4S direct/port injection strategies), VVT control, and stall detection. If it drops out, the car may not start, or it’ll run poorly and throw a check‑engine light.

It’s not a scheduled service item, but it’s smart to keep an eye on basics: tidy wiring under the bonnet, no oil seeping onto the connector, and no chafed looms near the front of the engine. If the 2020 IS shows long cranks, random stalling, or the tacho flicks dead while driving, scan for codes like P0335–P0339.

Replacement is straightforward for a competent home mechanic, though many owners will prefer a workshop:

• Disconnect the battery and raise the front if access from underneath is needed (remove the under‑tray).
• Unplug the sensor, remove the hold‑down bolt, and gently twist the sensor free. Expect an O‑ring seal.
• Lightly oil the new O‑ring, install the sensor square to the bore, and torque the bolt to spec from the Lexus repair manual.
• Clear fault codes and confirm clean live data for engine speed on a scan tool.

Tips a good tech will follow: check for metal fuzz on the sensor tip, verify the reluctor teeth aren’t damaged, and inspect nearby cam sensors and grounds if the fault’s intermittent. Genuine or high‑quality aftermarket sensors are recommended, cheapies can cause hot‑soak no‑starts. There’s no special relearn on these engines—once fitted correctly, the ECM recognises the signal and you’re off. If the vehicle’s still under any warranty programme, it’s worth a quick chat with a dealer before diving in.

• Popular questions related to 2020‑lexus‑is crank‑angle‑sensor

Does a 2020 Lexus IS have a crank‑angle sensor?
Yes. Lexus service manuals for the 8AR‑FTS and 2GR‑FKS/FSE engines specify a crankshaft position (crank‑angle) sensor that the ECM uses for ignition, injection, and VVT control.

Where is the crank‑angle sensor on a 2020 Lexus IS?
It’s mounted at the engine block/timing cover by the crankshaft. On the 2.0T it’s accessed near the front of the engine, on the V6 it’s likewise positioned at the timing cover area. Access often improves from underneath after removing the engine under‑tray.

Can you drive with a failing crank‑angle sensor?
Not recommended. A dodgy CKP can cause sudden stalling, hard starting, or no‑start. If the engine light is on with P0335‑type codes, it’s best to sort it promptly or get the vehicle towed to avoid being stranded.
