Parts for your 2011 Nissan Pulsar-Crank angle sensor

2011 Nissan Pulsar crank angle sensor

Yes — the 2011 Nissan Pulsar uses a crank angle sensor (also known as a crankshaft position sensor). Nissan’s factory service literature for the C11 platform (sold locally as Tiida during these years, but commonly referred to as Pulsar) describes the “Crankshaft Position Sensor (POS)” as a core input to the engine control module for ignition and injection timing (Nissan C11 EC section). Earlier N16 Pulsar service manuals outline the same function, and common diagnostic references such as Autodata and Bosch engine management guides list a CKP/CAS on MR18DE/HR16DE engines fitted to 2011 models. So, it’s absolutely relevant on this vehicle.

What does it do? The crank angle sensor tracks the crankshaft’s exact position and rotational speed via a toothed reluctor. The ECU uses that signal to fire the coils and injectors at the right moment, manage idle, and monitor misfire. If the signal drops out or goes noisy, the engine can be hard to start, stall at idle, or not start at all. The check engine light will often log codes like P0335 or P0336.

On the 2011 Pulsar/Tiida, the sensor is mounted on the engine block near the transmission end, low down. It’s a simple two-wire or three-wire hall/inductive unit secured by a single bolt. It isn’t a scheduled service item, but it’s smart to check the harness and connector during routine servicing — look for oil intrusion, brittle insulation, or a loose fit. If replacing, choose a quality sensor (genuine or reputable aftermarket), lightly oil the O-ring, and tighten the retaining bolt to the manufacturer’s spec (around 8–10 N·m). Clear codes and verify cranking RPM on a scan tool, the engine should show stable RPM during crank.

Typical signs it’s time to replace:

• Extended cranking or intermittent no-start when hot
• Random stalling at idle or low speed
• Check engine light with P0335/P0336, sometimes P0725

Before condemning the sensor, technicians will often inspect the wiring back to the ECU, check for mechanical damage at the reluctor, and verify battery and earths. Where applicable, completing any idle relearn after repairs helps drivability. With a healthy crank angle sensor, the 2011 Pulsar runs cleaner, starts reliably, and keeps fuel economy in check — an easy win for peace of mind across Aussie and Kiwi roads.

FAQs

Where is the crank angle sensor on a 2011 Nissan Pulsar?
It’s fitted low on the engine block near the transmission/bellhousing side. From under the car, look up around the rear of the engine, you’ll see a small sensor held by a single bolt with a two- or three-pin connector. Access is usually easiest from underneath with the splash shield removed.

What fault codes point to a bad crank angle sensor?
The most common are P0335 (Crankshaft Position Sensor “A” circuit) and P0336 (range/performance). You may also see P0725 (engine speed input). If those appear with hard-start or stall symptoms, the sensor or its wiring is a prime suspect.

Does the crank angle sensor need routine replacement?
No. It’s not a scheduled service item. Replace it only if it’s faulty or damaged. During routine services, a quick visual check of the connector and loom for oil contamination or chafing is worthwhile, especially on higher-kilometre cars.
