Parts for your 2013 Nissan Dualis-Crank angle sensor

2013 Nissan Dualis crank angle sensor — what it does and when to replace it

Yes, the 2013 Nissan Dualis (J10) uses a crank angle sensor, also called the crankshaft position sensor (CKP). This is confirmed by Nissan’s J10 Series factory service manual (EC section) for the MR20DE/HR16DE petrol and M9R/K9K diesel engines, which details the CKP/POS sensor operation and diagnostics (including DTCs P0335 and P0339), and by Nissan parts catalogues listing a crankshaft position sensor for these engines (e.g., 23731‑EN21A/23731‑6N21A). So it’s absolutely relevant to this model.

On the 2013 Nissan Dualis, the crank angle sensor is the little timekeeper that lets the engine control module know exactly where the crankshaft is and how fast it’s rotating. Using a toothed target wheel, the sensor feeds precise signals the ECU needs to fire the spark and inject fuel at the right moment, manage idle quality, detect misfires and keep cold starts crisp. If that signal goes missing or gets noisy, the Dualis can be hard to start, stall at idle, lose power, or throw a check engine light.

There’s no scheduled replacement interval for the sensor, but it lives a tough life near heat, oil mist and vibration. Common clues it’s on the way out include long cranking, intermittent no‑start when hot, sudden cut‑outs, or a CEL with P0335/P0339. During routine services, it’s smart to eyeball the connector and wiring where it runs past the bellhousing, clean away road grime, and make sure there’s no oil wicking into the plug. A quick scan‑tool check for steady RPM during cranking is a handy health check.

When replacement is needed, it’s a straightforward job: on most MR20DE Dualis models the sensor sits low on the gearbox bellhousing, reading the flywheel. Disconnect the battery, safely raise the vehicle, unplug the sensor, remove the single retaining bolt, and twist the sensor free. Lightly oil the new O‑ring, seat the sensor, and torque the bolt to snug (around 8–10 N·m). Clip the loom back properly, clear any codes, and road‑test. No programming is typically required, though an idle/throttle relearn after battery disconnect can help. Allow about 0.5–1.0 hour. Sticking with a genuine or quality OE‑equivalent sensor avoids repeat faults. If a fresh sensor doesn’t resolve a P0335/P0339, check the cam sensor, harness integrity, and the flywheel/reluctor for damage.

Where is the crank angle sensor on a 2013 Nissan Dualis?

On most MR20DE petrol models it’s mounted low on the transmission bellhousing, reading the flywheel/drive plate. It can be accessed from under the vehicle. Diesel placements are similar but can vary, a quick check in the service info for the exact engine code is best.

Can a crank angle sensor be cleaned, or does it have to be replaced?

If the tip is simply contaminated with road grime or light oil mist, a careful clean with electronics‑safe cleaner may restore a good signal. However, most failures are internal (heat or age related), so replacement is the reliable fix. Don’t sand or scrape the sensing face, and always renew the O‑ring if it’s flattened or brittle.

Does the Dualis need programming after a crank sensor replacement?

Generally, no. The ECM reads the new sensor without coding. Clear any fault codes and road‑test. If the battery has been disconnected, performing an idle/throttle relearn can help stabilise idle, many scan tools can trigger this, or it can be done via the factory learn procedure.
