Parts for your 2011 Nissan Tiida-Crank angle sensor

2011 Nissan Tiida Crank Angle Sensor (Crankshaft Position Sensor)

Yes, the 2011 Nissan Tiida uses a crank angle sensor — more commonly called the crankshaft position sensor (CKP). This is confirmed by Nissan’s C11 Tiida Factory Service Manual (EC section), the Nissan FAST electronic parts catalogue, and mainstream parts catalogues that list a CKP for both HR16DE (1.6L) and MR18DE (1.8L) engines. Those sources show a dedicated CKP sensor mounted at the gearbox end of the engine block, working alongside the camshaft position sensor to control ignition and fuel injection timing.

The CKP’s job is to tell the engine control module exactly where the crank is in its rotation and how fast it’s spinning. The ECU uses that signal to fire the coils and injectors at the right moment, manage cold starts, detect misfires, and keep the Tiida running smoothly and efficiently. On the Tiida, it reads a toothed reluctor on the crank and outputs a clean timing signal the ECU can trust at idle, cruise, or a cheeky overtake.

There’s no scheduled servicing for the CKP in standard maintenance. It’s a sealed, solid-state sensor. Still, it pays to keep an eye on things during routine servicing:

• Check the sensor connector and harness for oil contamination, brittle insulation, or loose clips.
• If there’s an engine or rear main seal leak, sort it — oil can find its way onto connectors and cause intermittent signals.
• If you’re chasing a hard-start, random stall, or a no-start with a dead tach on the scan tool, verify live RPM while cranking, scan for P0335–P0339 codes, and inspect the CKP wiring before condemning the sensor.

When replacement is needed, it’s a straightforward DIY for a confident home mechanic with stands and basic spanners. Disconnect the battery, safely raise the front, locate the sensor at the bellhousing end of the block, unplug it, remove the retaining bolt, and ease the sensor out. Lightly oil the new O-ring, seat the new unit, and tighten the bolt to about 9 N·m (per Nissan FSM guidance). Clear fault codes and road test, most cars won’t require special relearn, but a crank pattern or idle learn may be needed if prompted by your scan tool. Genuine or quality OEM-equivalent parts (e.g., Nissan 23731-EN20A/EN21A, confirm by VIN/engine) are recommended to avoid repeat faults and flaky signals.

• Where is the crank angle sensor on a 2011 Nissan Tiida?
  It sits at the gearbox/bellhousing end of the engine block, reading a reluctor on the crank. On the transverse Tiida, access is typically from underneath, near the rear of the engine, behind the engine mount area. Removing the lower splash shield often makes life easier.
• What are the common symptoms of a failing CKP on a Tiida?
  Hard starting (especially hot), random stalling, rough running, no-start, and a Check Engine Light. Scan tools often show codes like P0335–P0339, and live data may show zero RPM while cranking.
• Does the CKP need regular servicing or replacement by time/km?
  No scheduled interval. Replace only if faulty or damaged. During routine services, just check the connector and loom routing, and address any oil leaks that might contaminate it.
