Parts for your 2011 Toyota Wish-Camshaft sensor

2011 Toyota Wish camshaft sensor — what it does and when to service it

Based on Toyota technical literature for the ZGE2# series (New Car Features for ZR engines, Repair Manual and EWD), the 2011 Toyota Wish is fitted with a camshaft position sensor. On the 1.8L 2ZR‑FAE and 2.0L 3ZR‑FAE engines, Toyota identifies this component as the Camshaft Position Sensor (often labelled “G2”), mounted on the cylinder head to read the cam angle. It works with the crank sensor to manage fuel injection, ignition timing and VVT‑i/Valvematic operation, with related diagnostic trouble codes such as P0340 and P0341 listed in the factory DTC charts.

In everyday terms, the camshaft sensor tells the engine computer exactly where the cam is, so timing stays spot on from cold start to highway cruising. It helps the ECU phase valve timing smoothly, sharpen throttle response and keep emissions tidy. If it goes out to lunch, the ECU may fall back to a back‑up strategy, which can mean hard starting, rough idle, flat spots and the check engine lamp glowing.

There’s no scheduled replacement for the sensor itself, it’s a solid‑state unit designed to last. As part of routine servicing though, a quick look under the bonnet pays off. Check the sensor harness for chafing, brittle insulation or oil wicking up the loom, and make sure there’s no engine oil seeping past the sensor’s O‑ring into the connector. Oil contamination or metal fuzz on the sensor tip can upset the signal.

• Common clues it’s unhappy: hard starts, misfire at low revs, poor fuel economy, reduced power, and DTCs P0340/P0341.
• Quick checks: secure connector fit, clean pins, no cracked housing, and no oil leaks around the sensor.

When replacement’s on the cards, access is straightforward on the ZR engines: the sensor sits at the end of the cylinder head near the cam sprocket. Expect a single retaining bolt and an electrical plug. Fit a new O‑ring, lightly oil it, align carefully and tighten to the repair‑manual spec. After refitting, clear any fault codes and let the engine idle to relearn. If a fresh sensor doesn’t sort it, look for underlying issues like damaged wiring, a tired crank sensor, or sticky VVT oil control valves and their filters.

Quality matters here. A genuine or reputable aftermarket sensor matched to the 2ZR‑FAE/3ZR‑FAE is the go, and it shouldn’t be confused with the VVT solenoids—they live nearby but do a different job.

Popular questions about the 2011 Toyota Wish camshaft sensor

Where is the camshaft sensor located on a 2011 Toyota Wish?
On the ZR‑series engines it’s fitted to the cylinder head, typically at the end of the intake cam side near the timing chain area. Look for a small sensor with a single bolt and a two‑ or three‑pin connector under the plastic engine cover.

Access is usually from the top under the bonnet. A basic socket and a bit of patience with the connector clip is all that’s needed for inspection or replacement.

Can it be driven with a faulty camshaft sensor?
It may start and run in a limited back‑up mode, but it can stall, surge and chew through more fuel. Continuing to drive risks fouling the catalyst if misfires occur.

Best bet is to have the fault codes scanned and sort it promptly to avoid being stranded and to keep the engine running sweet as.

Does the 2011 Wish have one or two camshaft sensors?
For the 2ZR‑FAE and 3ZR‑FAE, Toyota documentation commonly shows a single camshaft position sensor used with the crank sensor for precise phasing. Some related Toyota engines use additional sensing strategies, but the Wish’s ZR setup typically uses one CMP.

If in doubt, check the engine code and wiring diagram for the exact variant by VIN.
