Parts for your 2000 Nissan Navara-Crank angle sensor

2000 Nissan Navara crank angle sensor – what it does and how to look after it

For the 2000 Nissan Navara (D22), a crank angle sensor is relevant on petrol models and generally not used on the same-year mechanical-diesel variants. The 2.4‑litre petrol (KA24E) Navara uses an optical crank angle sensor integrated inside the distributor, supplying the engine control unit with both position and reference signals. This setup is detailed in the Nissan D22 Series Service Manual (1997–2001, EC section), which describes the optical disc with multiple slots providing POS/REF signals within the distributor assembly. Gregory’s/Navara D22 workshop manuals and the Nissan FAST parts catalogue also show the sensor as part of the distributor sub‑assembly. By contrast, most 2000 diesels (TD27/QD32 with mechanical injection) don’t employ a crank angle sensor for engine management, while later common‑rail YD25 engines (from around 2001) use a separate crankshaft position sensor.

On the KA24E petrol, the crank angle sensor’s job is to tell the ECU exactly where the engine is in its rotation so it can fire the injectors and spark at the right moments. Housed in the distributor, an LED and photodiode read the slots on an optical wheel to create two key signals. If that signal goes missing or noisy, you’ll get hard starting, stalling, misfires, or a dead‑no‑start when hot. Fault codes can include cam/crank correlation style codes (often reported as P0340/P0335 on OBD‑II scan tools).

• Common symptoms: intermittent cut‑out, long crank/no start, erratic timing, poor fuel economy, and tachometer dropouts.
• Causes: age, heat soak, dust/moisture in the distributor, wiring/connectors, or worn distributor bearings affecting the optical gap.

Servicing advice for the 2.4 petrol: there’s no set replacement interval, but at higher kilometres or after water/dust ingress (common for utes used off‑road), it’s smart to inspect the distributor. Many workshops replace the whole distributor assembly rather than just the internal sensor because it also refreshes the shaft, bearing, cap/rotor and O‑ring. If replacing, mark the distributor and housing positions before removal. Disconnect the battery, remove the cap and rotor, unplug the connector, undo the hold‑down bolts, and lift the distributor out. Fit a new O‑ring, align the rotor to the original mark, refit, and set base ignition timing to factory spec with a timing light once warm (check the D22 EC section for exact KA24E timing and idle procedure).

For maintenance, keep the connector clean and the loom supported, check for oil weep into the distributor, and avoid blasting the optical window with aggressive cleaners. If the engine has been through deep water, pulling the cap to dry and inspecting for condensation can save headaches later.

Popular questions

Does a 2000 Navara diesel have a crank angle sensor?
Most 2000 D22 diesels (TD27/QD32 with mechanical pumps) don’t run a crank angle sensor for engine control. Later common‑rail YD25 models introduced around 2001 do use a separate crankshaft position sensor mounted to read the crank or flywheel.

Where is the crank angle sensor on a 2000 Navara 2.4 petrol?
It’s built into the distributor. You won’t find a separate sensor on the block, the optical sensor sits under the distributor cap and reads an internal slotted disc, feeding the ECU with position signals.

Can the crank angle sensor be cleaned or tested?
You can check power/ground and signal with a multimeter or scope, and gently clean dust from the optical window. If there’s bearing play, oil contamination, or persistent signal faults, replacing the complete distributor is the reliable fix.
