2000 Toyota Echo/Yaris crank angle sensor

Technical sources confirm the 2000 Toyota Echo/Yaris (XP10, 1NZ‑FE) is fitted with a crank angle sensor, also called a crankshaft position (CKP) sensor. Toyota’s New Car Features for the 1NZ‑FE engine describes the CKP providing the “NE” signal to the ECM for ignition timing and fuel delivery, the Toyota Echo/Yaris Electrical Wiring Diagram (NCP10 series) shows the CKP in the engine control circuit, and the Haynes Workshop Manual for Toyota Yaris 1999–2005 likewise lists testing and fault codes (such as P0335/P0336) for this sensor. So yes—this part is relevant and used on this model.

On the 1NZ‑FE, the crank angle sensor monitors the exact position and rotational speed of the crankshaft via a toothed wheel on the crank. That signal is mission‑critical: it lets the ECM fire the coils at the right moment, deliver fuel precisely, and coordinate with the camshaft sensor for VVT‑i and sequential injection. If the CKP drops out, the engine can be hard to start, misfire, or stall, if it dies completely, you’ll usually get a no‑start and a check engine light.

There’s no scheduled replacement interval for the CKP, it’s a “fit and forget” item until symptoms or fault codes appear. As part of routine servicing, it’s smart to visually check the sensor connector and harness routing near the crank area for oil contamination, damaged insulation, or loose clips. Keeping oil leaks in check around the timing cover also helps protect the sensor and plug.

Replacement is straightforward for most workshops: disconnect the battery, unplug the CKP, remove its retaining bolt, and withdraw the sensor and O‑ring. Lightly oil a new O‑ring, install the new sensor, and tighten to the manufacturer’s spec. Clear any codes and verify with live data or a scope if available. On these Toyotas, a special relearn is typically not required—the ECM recognises the signal immediately—but always confirm with scan‑tool data. Use a quality OEM or reputable aftermarket sensor, cheap copies can produce weak or noisy signals that keep the fault coming back.

Common signs it’s time to test or replace include:

• Long crank/no start, intermittent stalling, or rough running
• Check engine light with P0335/P0336 or crank/cam correlation codes like P0016
• Erratic tachometer or sudden loss of power

Because a failing CKP can mimic coil or fuel faults, proper diagnosis matters. Following Toyota’s test procedure—resistance checks on a magnetic pick‑up style sensor and signal inspection while cranking—helps avoid guesswork.

FAQs

Where is the crank angle sensor on a 2000 Echo/Yaris?
It’s mounted to the engine near the crankshaft, reading a toothed reluctor wheel. On the 1NZ‑FE it’s fixed to the block/timing cover area, low on the engine, with a short harness to the main loom. Access is from the front or side, depending on market and engine bay layout.

What fault codes point to a bad crank angle sensor?
P0335 (Crankshaft Position Sensor “A” Circuit) and P0336 (Range/Performance) are the classics. You might also see P0016 (crank/cam correlation) if timing signals don’t line up—sometimes due to chain stretch or a wiring issue—so confirm before replacing parts.

Do I need to perform a relearn after replacing it?
On this model, usually not. Clear the codes, start the engine, and check live data. If everything’s healthy, the ECM will use the new signal without special procedures.
