Parts for your 2007 Nissan Dualis-Crank angle sensor

2007 Nissan Dualis crank-angle sensor: purpose, care and when to replace

Based on the Nissan Qashqai/Dualis J10 factory service manual (EC section, 2007), the MR20DE engine manual, and Nissan FAST parts catalogues for the J10 series, the 2007 Nissan Dualis is fitted with a crankshaft position sensor (often called a crank-angle sensor). It’s used across the common 2007 Dualis engines (MR20DE petrol, HR16DE petrol, and the K9K/M9R diesels) and is tied to OBD-II fault codes such as P0335–P0339 documented in Nissan diagnostic literature.

This little sensor is the timing boss. It tracks crankshaft speed and exact position, feeding that data to the ECU so it can fire the injectors and spark at the right moment. Without a good signal, the engine can crank but not start, stall randomly, or feel flat and misfire. It also works in tandem with the cam sensor to confirm cylinder identification for sequential injection and ignition.

• Typical symptoms of a crook crank-angle sensor: hard starting or no start when hot, sudden stalling at idle, erratic rev counter, poor fuel economy, and the MIL on with P0335-style codes.
• Common causes: heat soak, vibration, oil contamination at the O-ring, or wiring/connector damage near the bellhousing.

It’s not a routine service item, but it’s worth inspecting during major services—particularly if the Dualis has done a lot of urban kilometres or towing. Check the loom routing and connector for corrosion, ensure the retaining clip is snug, and look for oil weep around the sensor’s O-ring. If diagnosing, use a scan tool to confirm RPM while cranking and check for related DTCs, a multimeter or scope test should follow the workshop manual specs for the exact engine variant.

1. Replacement is straightforward: disconnect the battery, access the sensor (usually low on the block near the transmission bellhousing on the MR20DE), remove the single retaining bolt, twist out the sensor, lube a new O-ring, and refit.
2. Torque the bolt to the spec in the Nissan service manual, clip the connector firmly, clear codes, and verify clean RPM signal and stable idle.

Go for a quality OEM-equivalent sensor, cheapies can be fussy with signal quality. No coding is typically required on the J10—just clear the codes and road test. If issues persist, inspect the reluctor ring and engine grounds, and check live data for crank/cam sync.

Where is the crank-angle sensor on a 2007 Dualis?

On most MR20DE petrol models it’s mounted low on the engine block at the gearbox side, reading a trigger wheel near the flywheel. On HR16DE and the K9K/M9R diesels, location is similar—low and near the bellhousing. Access may be from under the vehicle, removing the undertray makes life easier.

Can you drive with a failing crank-angle sensor?

Sometimes the car will run but stumble or stall, other times it won’t start once hot. It’s risky to keep driving because the engine can cut out without warning. Best bet is to address it promptly to avoid getting stranded.

Do you need to reprogram anything after replacing it?

On the Dualis J10, no special coding is usually required. Clear the fault codes, start the engine, and let it idle for a few minutes. Some scan tools offer a crank/cam relearn, but the ECU generally adapts on its own if the signal is clean and wiring is sound.
