2017 Toyota Crown Camshaft Sensor: what it does and how to look after it

Yes, the 2017 Toyota Crown uses a camshaft position sensor. Toyota’s factory repair information (TIS) for the S210-series Crown includes diagnostic procedures for the Camshaft Position Sensor (often labelled “G” signal) across the 8AR‑FTS 2.0L turbo, the 2AR hybrid four-cylinder, and V6 variants, and the Toyota OBD-II DTC set lists camshaft sensor faults such as P0340/P0345 for these engines. Toyota’s Electronic Parts Catalogue for S210 models also shows camshaft position sensor listings for the same powertrains. Those sources confirm the sensor is standard kit on this model.

On a 2017 Toyota Crown, the camshaft sensor tells the ECU exactly where each cam is in its rotation so it can time fuel injection and spark, and command VVT-i/VVT-iW to shift cam timing on the fly. It’s also crucial for smooth starts (including hybrid engine restarts), clean idle, and crisp throttle response. If the signal goes walkabout, the Crown can take longer to crank, run rough, lose power, and throw a check engine light.

There’s no scheduled replacement for the camshaft sensor, it’s a solid-state part designed to last. Good oil is its best mate. Sticking to the factory oil grade and change intervals keeps the timing gear and tone wheels clean, which helps the sensor read accurately. During routine servicing, it’s worth a quick look under the bonnet to check the sensor connector and harness for oil ingress or brittle insulation, especially on higher‑kilometre cars or vehicles used in hot climates.

Common signs a camshaft sensor might be crook include:

• Hard or extended cranking, intermittent stalling, or a lumpy idle
• Noticeable drop in power or fuel economy
• Check engine light with codes like P0340/P0341/P0345

Replacement on the Crown is generally straightforward. The sensor lives on the cylinder head near the timing cover, some variants run one sensor, while V6 models may run one per bank. A quality OEM or OE‑equivalent sensor is recommended, fitted with a fresh O‑ring, and tightened to the light factory torque. It’s smart practice to disconnect the battery, keep the connector clean and dry, clear fault codes, and take a proper road test. If a new sensor doesn’t sort the issue, a tech should check the wiring, cam timing targets, and oil control system for the VVT – Toyota’s TIS flowcharts cover these checks in detail.

They don’t typically fail often, but a quick inspection at major services (say, every 100,000 km) helps catch minor issues before they become dramas.

Popular questions about 2017 Toyota Crown camshaft sensors

Does the 2017 Crown have more than one camshaft sensor?
It depends on the engine. The turbo and hybrid four‑cylinders commonly use a single cam sensor on the head. V6 variants generally use two – one for each bank. The Toyota parts catalogue for S210 models reflects these layouts.

Can driving with a faulty camshaft sensor cause damage?
It usually won’t hurt the engine immediately, but it can cause misfires, rough running, and rich mixtures that aren’t great for the catalytic converters. Best to sort it promptly to avoid poor fuel economy and unnecessary wear.

How long does replacement take and what might it cost?
On four‑cylinder Crowns, expect roughly 0.5–1.0 hour of labour, V6 cars can take a bit longer due to access. Parts pricing varies by brand, but budgeting for an OEM or quality aftermarket sensor is wise to keep the check engine light away.
