Parts for your 2014 Holden Barina-Crank angle sensor

2014 Holden Barina crank angle sensor — what it does and how to look after it

Based on technical sources, the 2014 Holden Barina (TM series, T300 platform) is fitted with a crank angle sensor, also known as a crankshaft position (CKP) sensor. GM Global Service Information (SI) for the Barina/Sonic lists CKP sensor diagnostics and replacement procedures, the Holden Electronic Parts Catalogue (MY14 TM) includes a crank sensor in the engine controls group, and major component catalogues (Bosch/Delphi) list a CKP for both the 1.8 petrol and 1.4 turbo engines used in this model. So yes—this part is very much relevant to the 2014 Barina.

The Barina’s crank angle sensor reads a toothed wheel on the crankshaft to tell the engine control module exactly where the pistons are and how fast the engine’s spinning. That precise timing lets the ECU fire the coils and injectors at the right moment, keeps starting crisp, and helps with smooth idle and fuel economy. It also works hand‑in‑hand with the cam sensor for proper synchronisation.

There’s no regular service interval for the sensor itself, but checking the wiring and connector during routine servicing is smart—heat, oil seepage and road grime can make the plug brittle or contaminated. Typical warning signs of a failing CKP include an intermittent no‑start when hot, stalling as the car warms up, misfires, a dead tacho during crank, and a check‑engine light (often codes like P0335/P0336).

Replacement is usually straightforward: it’s mounted low on the engine block, reading the crank trigger wheel. Access is often from underneath, disconnect the battery, unplug the connector, remove the retaining bolt, and ease the sensor out (it’s sealed with an O‑ring). Lightly oil the new O‑ring, seat the sensor squarely, and tighten to the manufacturer’s torque spec. After fitting, clear fault codes and, on some Barinas, perform the crankshaft variation learn with a scan tool so the ECU knows the new signal profile. If the connector or harness looks heat‑soaked or oil‑soaked, replace or repair it at the same time to avoid comeback faults.

Because a dying crank angle sensor can cause sudden stalling, it’s worth acting early. If the Barina is cranking but not firing, or it cuts out when hot and restarts after cooling, this sensor should be high on the shortlist for diagnosis.

• Common symptoms: hot no‑start, random stalling, misfire, rough idle, check‑engine light.
• Good practice: inspect connector integrity, routing and sealing during every major service.
• After replacement: clear codes and complete a relearn procedure if required.

Popular questions about the 2014 Holden Barina crank angle sensor

Does a 2014 Holden Barina actually have a crank angle sensor?
Yes. GM’s service documentation for the TM Barina/Sonic platform details the CKP sensor’s role and replacement, and the Holden EPC and major aftermarket catalogues list the part for both available engines. It’s a core input for ignition and fuel timing.

What are the tell‑tale signs the Barina’s crank sensor is failing?
Look for intermittent no‑start (especially when hot), sudden stalling, rough running, a dead or jumpy tacho while cranking, and a check‑engine light with codes like P0335/P0336. These symptoms can overlap with cam sensor and wiring faults, so a proper scan and signal check is wise.

Can it be driven with a dodgy crank angle sensor?
It might start and run one moment then stall the next, which isn’t safe. Because the sensor signal is critical for spark and fuel timing, a failing CKP can leave the car stranded. Best bet: diagnose promptly, and replace the sensor (and any damaged wiring) before it escalates.
