Parts for your 2005 Daihatsu Yrv-Crank angle sensor

2005 Daihatsu YRV crank angle sensor: what it does and how to look after it

Based on factory and trade documentation, the 2005 Daihatsu YRV is fitted with a crank angle sensor (also called a crankshaft position sensor). The Daihatsu YRV/M2-series workshop manual for Engine Control Systems describes the NE (crank) and G (cam) inputs used by the Denso ECU, with the crank sensor mounted at the front of the engine. The Daihatsu Electronic Parts Catalogue (YRV M200/M201/M211) lists a dedicated crankshaft position sensor for the K3-VE/K3-VET engines, and mainstream service data tools (e.g., Autodata/Bosch ESI) show diagnostic pinouts and fault codes (P0335/P0336) for this sensor on the 2005 model. In short: yes, this vehicle uses a crank angle sensor.

On a 2005 Daihatsu YRV, the crank angle sensor is the ECU’s timekeeper. It watches a toothed wheel on the crankshaft and feeds the ECU a precise signal about engine speed and crank position. The ECU then fires the spark and meters the fuel at exactly the right moments, keeps idle stable, coordinates with the cam sensor for sequential injection, and tracks misfires. If the crank sensor drops out, the YRV can be hard to start, stumble, or simply cut out under the bonnet without warning.

It’s a sealed, no-adjustment part, so there’s no routine service interval. During regular servicing, it’s smart to give the sensor connector and harness a look—make sure the plug is snug, pins are clean, and the wiring isn’t rubbing on the block or sitting too close to the exhaust. On magnetic types, a light build-up of metallic fuzz on the tip can sometimes be cleaned carefully, but if the sensor has cracked insulation, oil ingress, or intermittent readings on a scan tool, replacement is the go.

Common red flags include a long crank/no start, random cut-outs, a twitchy tacho, and the check engine light with codes like P0335/P0336. Before throwing parts at it, confirm power, ground, and signal with a scope or a quality scan tool—faulty wiring near the timing cover is not unheard of.

Replacement is straightforward for a competent home spanner: disconnect the battery, unplug the sensor, remove its retaining bolt, swap in the new sensor with a fresh O-ring, and route the loom exactly as the factory did. Torque the bolt to the spec in the workshop manual, clear any codes, and let the ECU relearn its idle. Most quality aftermarket sensors work fine, but sticking with reputable brands helps avoid ghost faults.

• Typical symptoms: no start, stalling, rough idle, poor fuel economy, stored DTCs P0335/P0336.
• Preventive tip: inspect the connector and wiring each service, replace only when testing points to the sensor.

FAQs

Where is the crank angle sensor on a 2005 Daihatsu YRV?
It’s typically mounted at the front of the engine by the crank pulley/timing chain cover on K3-VE and K3-VET engines. You’ll find it low on the block with a two- or three-pin connector. Some variants may position it slightly differently, so checking the YRV workshop manual or a trusted service guide is wise before diving in.

What are the signs the YRV’s crank angle sensor is failing?
Hard starting or no start, random stalls, a jerky or dead tacho while cranking, and the check engine light are the big giveaways. A scan tool may show P0335 or P0336. If power and ground to the sensor test fine and the signal drops out hot, the sensor is likely on the way out.

Should it be replaced as preventive maintenance?
There’s no scheduled interval—these sensors usually last many years and kilometres. Treat it as condition-based: inspect the wiring at each service, keep the connector clean and clipped in, and only replace the sensor if tests confirm it’s faulty or if there’s physical damage or oil contamination.
