Parts for your 1997 Nissan Navara-Camshaft sensor

1997 Nissan Navara camshaft sensor — does it have one?

Whether a 1997 Nissan Navara uses a camshaft sensor depends entirely on the engine fitted. Technical references including the Nissan D22 Factory Service Manual (EC section for KA24E petrol), Nissan diesel engine service manuals for TD27/QD32 (Engine Mechanical and Fuel sections), and the Nissan FAST parts catalogue indicate: the KA24E 2.4 petrol Navara uses a camshaft position sensor integrated into the distributor, while the mechanically injected TD27 or QD32 diesels of that era do not use a camshaft sensor at all.

Why some 1997 Navaras don’t use one: the TD27 and many QD32 variants run a fully mechanical injection pump with timing set by gears and the pump itself, so there’s no need for a separate camshaft phase input. These engines may rely on basic pump and crank references (and sometimes a flywheel/“TDC” pickup on certain ETi variants), but there’s no dedicated camshaft position sensor like on the petrol. That’s consistent with the diesel fuel system layouts shown in Nissan’s diesel FSMs for those engines.

For KA24E petrol models where a camshaft sensor is fitted, it lives inside the distributor and is used as the phase reference for spark and fuel control. Nissan’s EC documentation describes this optical sensor (often called a cam angle or phase sensor) providing the ECU with the cylinder identification signal so it can sync injection and ignition properly, especially during start-up and at idle.

On a 1997 Navara KA24E, the camshaft sensor’s job is simple but critical: it tells the ECU which stroke each cylinder is on so the spark and fuel events line up. If it drops out, the ute can become hard to start, misfire, stall, or throw a fault like P0340. As part of servicing, it’s a good idea to inspect the distributor area every 20,000–40,000 km: check the harness plug and earths, look for oil ingress from a leaking distributor shaft seal, and make sure the cap/rotor (if fitted to your distributor variant) aren’t worn. A shot of contact cleaner on the connector and ensuring the loom isn’t rubbing on the rocker cover can prevent intermittent faults.

Replacement is usually straightforward: disconnect the battery, mark the distributor’s current position for timing, unplug the connector, and remove the distributor to service or replace the sensor (often the whole distributor assembly is replaced because the internal sensor isn’t always sold separately). After refit, set base ignition timing to spec using a timing light per Nissan’s EC procedure. Avoid cheap pattern distributors—poor-quality sensors can cause random cut-outs when hot. If the ute still cranks with no start, check the crank angle reference and the ECU power/grounds as well, the cam and crank signals work together.

• Typical symptoms: long crank, stumble off idle, random stall, poor economy, check engine light.
• Good practice: keep connectors clean and dry, fix oil leaks into the distributor, verify timing after any work.

Popular questions about 1997 Nissan Navara camshaft sensors

Where is the camshaft sensor on a 1997 Navara?
On KA24E petrol models, it’s built into the distributor on the front/side of the engine. The ECU reads the optical signal from inside that housing. On TD27 or QD32 mechanical diesels, there isn’t a camshaft position sensor fitted.

What are the signs the camshaft sensor is failing?
Hard starting, erratic idle, misfires, sudden stalling when hot, and a stored fault code like P0340 are common. If those show up on a KA24E, check the distributor wiring and cap/rotor first, then consider the internal sensor. For diesel mechanical models, look elsewhere—fuel delivery and glow systems are more likely.

Can the camshaft sensor be cleaned, or does it need replacing?
You can clean the distributor connector and ensure no oil has crept inside. The internal optical sensor itself isn’t really a clean-and-carry-on item, if it’s failing, replacement (often of the whole distributor) is the reliable fix. After replacement, set base timing to spec so it behaves nicely on Aussie and Kiwi roads.
