Parts for your 2001 Daihatsu Yrv-Crank angle sensor

2001 Daihatsu YRV crank angle sensor — purpose, fitment, and service tips

Referencing the Daihatsu YRV M200/M201/M211 Series Workshop Manual (Engine Control section), the Daihatsu Electronic Parts Catalogue for the K3-VE and K3-VET engines, and Autodata’s engine management listings for 2000–2005 Daihatsu YRV, this model is indeed fitted with a crankshaft position sensor — commonly called a crank angle sensor. The manual identifies it as the NE (crank) signal used by the Denso ECU, with a companion camshaft (G) signal. On the K3-VE/K3-VET, the sensor is mounted at the timing chain cover where it reads a reluctor on the crankshaft.

On a 2001 Daihatsu YRV, the crank angle sensor’s job is to tell the ECU exactly where the crank is in its rotation and how fast it’s spinning. That info lets the ECU time spark and fuel with precision, stabilise idle, and manage variable valve timing on applicable variants. When it’s healthy, cold starts are crisp, throttle response is tidy, and fuel economy stays on song. When it’s crook, expect hard starting, stumbling or stalling, and the MIL on with fault codes like P0335/P0336.

This isn’t a scheduled replacement item in Australia or New Zealand, it’s a fix-on-failure part. As part of regular servicing, it’s smart to:

• Visually check the sensor connector and loom for heat damage, brittle insulation, or oil contamination around the timing cover.
• Confirm the harness is clipped away from the auxiliary belt and exhaust.
• Scan for stored or pending faults even if the light isn’t on, especially after hard starting episodes.

If replacement is needed, quality matters — stick with a reputable OE-equivalent (Denso is common on these). Disconnect the battery, let the engine cool, and work from above or below depending on access. The sensor sits on the timing cover, held by a small fastener and sealed by an O-ring, a light smear of clean engine oil on the new O-ring helps seating. Avoid overtightening, route the lead exactly as per the original clips, then clear codes and road test. Typical workshop time is around 0.5–1.0 hour, though corrosion or tight access can stretch that.

A fresh sensor won’t fix a damaged trigger wheel or wobbly crank pulley, so if symptoms persist after replacement, have a technician check pulley condition, timing cover alignment, and any oil leaks that could be spoiling the signal.

Where is the crank angle sensor on a 2001 Daihatsu YRV?

It’s mounted on the timing chain cover at the front of the engine, reading the crankshaft reluctor. Access is usually from the top, with better access from underneath on some cars. Turbo (K3-VET) models share a similar mounting point.

What are common symptoms and fault codes when it fails?

Hard or no start when hot, intermittent stalling, rough idle, and poor fuel economy are common. The check engine light may log P0335 (crankshaft position sensor “A” circuit) or P0336 (range/performance). Wiring damage can mimic sensor failure, so test before replacing.

Should it be replaced as preventative maintenance?

There’s no routine interval. Replace only if it’s faulty or if the connector or wiring is heat-soaked or oil-soaked. During regular servicing, a quick inspection and a scan for pending codes is the best preventative step.
