Parts for your 2000 Holden Barina-Crank angle sensor

2000 Holden Barina crank-angle sensor: what it does and how to look after it

Based on Holden/GM Service Information for the SB-series Barina (Opel Corsa B, 2000 model year), the Haynes Corsa 1993–2000 manual, and Bosch engine-management documentation for these small GM petrol engines, the 2000 Holden Barina is fitted with a crankshaft position sensor (often called a crank-angle sensor or engine speed sensor). It reads a toothed wheel on the crank/flywheel to give the ECU precise engine speed and position. So yes—this part is relevant and used on the 2000 Barina.

On this Barina, the crank-angle sensor is critical. It lets the ECU know exactly where the crank is, so it can fire the spark and inject fuel at the right moment. If it drops out, the car can be hard to start, stall when hot, misfire, or refuse to kick over at all. Fault codes commonly logged include P0335/P0336, and the tacho may sit dead while cranking.

It isn’t a scheduled service item, but it does live a tough life near heat, oil mist and vibration. As part of routine servicing on a 2000 Barina, it’s smart to:

• Visually check the sensor harness and connector for rubbing, cracked insulation, or oil contamination.
• Make sure the wiring is clipped away from the exhaust and driveshafts.
• Address oil leaks (rocker cover, rear main) that can soak the sensor.

If replacement is needed, it’s a straightforward job for a competent DIYer or any workshop. Disconnect the battery, raise the car safely, and find the sensor where the engine meets the gearbox bellhousing. It’s usually held by a single retaining bolt. Unplug it, ease it out, lightly oil the new O-ring, and refit the new sensor—routing the lead exactly like the factory did. Tighten to the workshop manual spec, reconnect, and clear any fault codes. Some scan tools offer a crank-learn routine, on these engines it’s often not mandatory, but it doesn’t hurt if your tool supports it.

Going for a quality OEM-equivalent sensor pays off—cheap units can be fussy about signal quality when hot. After fitting, a quick road test to confirm clean starting, smooth idle, no cut-outs, and no returning codes is the go.

FAQs

Where is the crank-angle sensor on a 2000 Holden Barina?
It’s mounted low on the engine where the block meets the gearbox bellhousing, reading a toothed wheel on the crank/flywheel. Access is usually from underneath, look for a small sensor with a single bolt and a two- or three-pin plug.

What are the signs of a failing crank-angle sensor on a Barina?
Hard starting, intermittent stalling when hot, random misfires, a dead tacho during cranking, and fault codes like P0335 are classic. Often it will restart after cooling down, then cut again once warm.

Do I need to perform a relearn after replacing the sensor?
Many 2000 Barinas will run fine without a special relearn. That said, if your scan tool supports a crank variation learn, running it is good practice and can help the ECU nail down precise timing straight away.
