2000 Daihatsu YRV camshaft sensor — what it does and when to replace it
Yes, the 2000 Daihatsu YRV uses a camshaft position sensor. Technical references including the Daihatsu YRV (M200 series) workshop manual, Daihatsu K3-VE/K3-VET engine service information, and Autodata component-location guides confirm a dedicated camshaft sensor fitted in the cylinder head. It’s required for sequential fuel injection and for managing Daihatsu’s variable valve timing on K3-VE/K3-VET engines. Parts catalogues for the period list the sensor and its O-ring as service-replaceable items, so it’s very much part of the car’s engine management.
On the YRV, the camshaft sensor tells the ECU where the intake cam is in its rotation. That lets the ECU fire injectors in the right order, line up spark on the money at start-up, and juggle valve timing smoothly. When the sensor signal goes off, the ECU can fall back to a limp or batch mode, which means longer cranks, rough idle and a fair whack less go under the right foot.
- Common clues it’s unhappy: hard starting (especially cold), misfires at idle, flat spots on acceleration, poor fuel economy, and the MIL on.
- Typical fault codes: P0340 (Camshaft Position Sensor Circuit) or P0341 (Range/Performance).
There’s no routine “service” for the sensor itself, but it’s smart to check it when the bonnet’s up for scheduled servicing: look for oil weeping into the connector, brittle wiring near the plug, or damage from previous work around the timing cover. A light film of clean engine oil on the O-ring is fine, actual oil contamination in the plug is not.
- Disconnect the battery and let the engine cool.
- Locate the sensor at the end of the cylinder head (access varies, a small mirror helps).
- Unplug the connector, remove the retaining bolt, and ease the sensor out. Don’t pry on the plastic body.
- Fit a new O-ring, lightly oil it, install the new sensor, and tighten the bolt to the workshop spec.
- Reconnect, clear codes with a scan tool, and road test. Check live data to confirm stable cam signal and VVT operation.
If faults persist after replacement, inspect the harness for high resistance and check the timing chain alignment and cam trigger wheel. Use quality OEM-equivalent parts, cheap clones can give flaky signals and ghost codes that waste time.
Popular questions
Does the 2000 Daihatsu YRV have a camshaft position sensor?
It does. Factory literature for the M200-series YRV and K3-VE/K3-VET engines specifies a camshaft position sensor mounted in the head. It’s essential for sequential injection and managing valve timing.
What are the signs a YRV camshaft sensor is failing?
Expect longer cranking, rough idle, flat spots, increased fuel use, and a check-engine light. Scanning often shows P0340 or P0341. Visual checks may reveal oil in the connector or cracked wiring under the loom tape.
Can you drive with a faulty camshaft sensor?
Usually the car will run, but it may start poorly, use more fuel and feel sluggish. It’s safe only short-term, leaving it can mask other issues and may stress the catalyst with misfires. Best to diagnose and sort it promptly.
