2007 Lexus IS Crank Angle Sensor — Yes, It’s Fitted and It Matters

According to Toyota/Lexus factory repair manuals (Engine Control System sections for 4GR‑FSE, 2GR‑FSE and 2AD engines) and the Toyota/Lexus Electronic Parts Catalogue, the 2007 Lexus IS range uses a crankshaft position sensor, commonly called a crank angle sensor (signal “NE” in Toyota documentation). It’s present on IS250 (4GR‑FSE), IS350 (2GR‑FSE) and markets that received the IS220d (2AD). So, it’s definitely relevant and fitted to the 2007 Lexus IS.

On a 2007 Lexus IS, the crank angle sensor is the timekeeper for the engine. It constantly monitors the crankshaft’s position and speed, feeding that info to the ECU so it can fire the injectors and coils at precisely the right moment. That tight coordination is what gives the IS its smooth idle, sharp throttle response and good fuel economy. If that signal goes missing or gets messy, the ECU can’t keep things in sync — which is why a dodgy sensor can cause cranking with no start, random stalling, misfires, or a check engine light with codes like P0335/P0339.

It’s not a routine replacement item like oil or spark plugs, so there’s no set interval. Still, it pays to keep an eye on it during regular servicing. Under the bonnet, a quick visual once-over of the sensor body and the wiring loom is worth doing — look for oil weep at the sensor O‑ring, brittle conduit, rubbed-through insulation, or loose connectors. Intermittent hot‑soak no‑start complaints and sudden cut-outs are classic signs to scan for fault codes and live data (crank signal RPM) before throwing parts at it.

When replacement is needed, it’s a straightforward job for a competent tech. The sensor sits at the engine block by the crank timing ring, access varies slightly between the V6 petrols and the diesel but generally involves disconnecting the plug, removing a single retaining bolt and gently twisting the sensor free. A light smear of clean engine oil on the new O‑ring helps it seat without pinching. Always use a quality OEM‑equivalent sensor, route the harness exactly as from factory clips, and tighten the fastener to the specification in the Lexus service manual rather than “by feel”. After installation, clearing codes and verifying clean crank and cam signals with a scan tool is the go, along with a proper road test to confirm hot and cold starts are crisp.

• Typical symptoms: hard start/no start, stalling, rough running, MIL on (P0335/P0339).
• Service tip: inspect connector pins for corrosion and ensure good engine grounds before condemning the sensor.

Popular questions about the 2007 Lexus IS crank angle sensor

Where is the crank angle sensor located on a 2007 Lexus IS?

On the V6 petrol models (IS250/IS350), it’s mounted to the engine block near the crankshaft timing ring, accessed from the front or side of the engine, depending on market specifics and ancillary layout. On the IS220d, it’s similarly positioned at the block to read a toothed wheel on the crank.

Access usually involves removing intake ducting or covers for hand room. A service manual diagram makes spotting the connector and bolt a lot easier.

What are the signs the crank angle sensor is failing on this model?

Common clues include a crank/no‑start when hot, random stalling at idle or when coasting, uneven idle, and a check engine light with codes such as P0335 or P0339. Scan data will often show no RPM during cranking if the sensor has dropped out.

Because wiring faults can mimic a bad sensor, a quick continuity and pin-fit check is smart before replacement.

Does the crank angle sensor need regular servicing?

There’s no scheduled replacement interval. During routine services, a visual inspection for oil leaks at the sensor, brittle wiring, or loose connectors is sufficient. If symptoms or fault codes appear, test first and replace as required.

Using an OEM‑quality part and following factory torque and harness routing will help it go the distance for years and many kilometres.
