Parts for your 2013 Holden Barina-Crank angle sensor

2013 Holden Barina crank-angle-sensor

Based on GM Global Service Information (GMSi) for the 2013 Barina/Sonic “Engine Controls – Crankshaft Position (CKP) Sensor, Description and Operation”, the Holden Electronic Parts Catalogue (TM Barina, Group 6.170 “Sensor, Crankshaft Position”), and common OE supplier catalogues (ACDelco/Delphi listings for 2013 Barina), the 2013 Holden Barina is fitted with a crank-angle sensor (commonly called a crankshaft position or CKP sensor). It’s a core engine management input on both the 1.6-litre and 1.4-litre turbo variants.

On the 2013 Barina, the crank-angle sensor tells the engine control module exactly where the crankshaft is and how fast it’s spinning. That info lets the ECM fire the injectors and coils at the right moment, control idle, and keep emissions in check. Lose that signal and the Barina will crank but likely won’t start, or it may stall randomly. It’s paired with the cam sensor so the ECM knows which stroke each cylinder is on for neat, sequential fuelling.

It’s not a scheduled service item like oil or filters, but it deserves attention during regular servicing. A quick look for oil wicking into the connector, rub-through on the harness, or loose mounting is smart preventative maintenance. If the check engine light pops with codes like P0335–P0339, hot restarts get cranky, or there’s sudden stalling, the CKP is high on the suspect list.

Replacement isn’t a drama for a competent home mechanic, though many owners prefer a workshop. The sensor sits low on the engine block near the bellhousing area. Access is usually from underneath once the splash shield is off. Always disconnect the battery, unclip the connector, remove the retaining bolt, and twist the sensor gently to free the O-ring. A light smear of clean engine oil on the new O-ring helps it seat nicely. Tighten the bolt to the manufacturer’s spec and route the loom clear of heat and moving parts.

After fitting, clear any fault codes and perform a crankshaft position variation learn (often called a “case relearn”) with a scan tool. GM specifies this so the ECM can sync perfectly with the new signal and avoid misfire flags. If a fresh sensor doesn’t cure the grief, a tech should scope the signal and check the reluctor ring and wiring — the issue can be upstream of the sensor itself.

• Common symptoms: hard starting, intermittent stalling, rough idle, MIL on with P0335–P0339.
• Good practice: inspect wiring every 10,000–15,000 km services, keep oil leaks in check, and use quality OE-equivalent sensors.

FAQ

Where is the crank-angle sensor on a 2013 Holden Barina?
It’s mounted low on the engine near the bellhousing area, reading a toothed reluctor on the crank. Most techs access it from underneath after removing the lower splash shield. The electrical connector is close by on the engine harness — check for oil intrusion or corrosion while you’re there.

What are the signs the Barina’s crank-angle sensor is failing?
Typical clues are long crank times, hot no-starts, sudden stalls at idle or when coming to a stop, and the check engine light with codes like P0335. Because the ECM relies on this signal for spark and fuel timing, a failing sensor can feel like the engine simply “cuts out” without warning.

Do you need to program anything after replacing the sensor?
Yes — perform a crankshaft position variation learn with a suitable scan tool. GM calls this a CKP system variation learn. Skipping the relearn can lead to misfire detection issues and a returning MIL, even if the new sensor is spot on.
