Parts for your 2011 Holden Barina-Crank angle sensor

2011 Holden Barina crank angle sensor (crankshaft position sensor)

Technical sources confirm the 2011 Holden Barina is fitted with a crank angle sensor (commonly called a crankshaft position or CKP sensor). The Holden Barina TK (through 2011) and the late-2011-on TM both show a CKP sensor in their Engine Controls sections and wiring diagrams within Holden/GM Global Service Information and factory workshop manuals. Genuine Holden/ACDelco parts catalogues, along with well-known aftermarket catalogues for the Barina/Aveo/Sonic platforms, also list a CKP for 2011 models. These sources collectively make it clear the sensor is relevant and used on this vehicle.

On a 2011 Barina, the crank angle sensor reads a toothed wheel on the crankshaft to tell the ECU exactly where the crank is and how fast it’s spinning. That data is the backbone for spark timing, sequential fuel injection, and misfire detection. If the signal goes missing, the ECU can’t confidently fire the plugs or injectors, and the engine may not start at all.

This isn’t a routine service item, but it deserves attention during scheduled servicing. A quick visual once-over for oil contamination, chafed wiring, loose connectors, or damage near the sensor mounting is worthwhile—particularly if there are signs of oil leaks at the front or rear main seal. Most Barinas place the CKP low on the block near the crank pulley or bellhousing, access is typically from underneath.

• Common symptoms of a failing CKP: hard or no start when hot, random stalling, rough running, erratic tacho, and a Check Engine light with codes like P0335–P0339.
• Basic replacement tips:
  1. Disconnect the battery and safely raise the car.
  2. Unplug the sensor connector, remove the retaining bolt, and ease out the sensor.
  3. Lightly oil a new O-ring, seat the new unit, and torque the bolt to the spec in the service data.
  4. Route the loom correctly, clear fault codes, and perform a crank relearn if specified.

Quality matters here—use a genuine or reputable brand sensor to avoid signal noise or intermittent faults. Labour time is usually modest, and a shop scan after fitting ensures the ECU is happy. If the Barina is showing any of the tell-tale signs above, it’s smart to book it in before a no-start strands the driver at the servo.

FAQs

Where is the crank angle sensor on a 2011 Holden Barina?

On most 2011 Barinas, the CKP sits low on the engine block reading a reluctor on the crankshaft—either near the harmonic balancer at the front or at the transmission bellhousing. Access is commonly from under the car with the splash shield removed. Always confirm the exact spot against the engine variant and a service manual.

What are the symptoms of a failing Barina crank angle sensor, and is it safe to drive?

Expect intermittent no-start (often worse when hot), sudden stalling, rough idle, misfire, and a Check Engine light with crank sensor codes. It may run one minute and die the next. Driving is risky, a failing CKP can cut out without warning, so it’s best to diagnose and repair promptly.

Does the CKP need regular replacement, and what does it cost?

There’s no kilometre-based replacement interval. Replace only if faulty or damaged. Parts are generally affordable, and labour is typically under an hour, but it varies by engine layout and workshop. Choosing a quality sensor saves headaches with false codes or repeat failures.
