Parts for your 1997 Nissan Primera-Crank angle sensor

1997 Nissan Primera crank angle sensor — what it does and how to look after it

Based on the Nissan Primera P11 Factory Service Manual (EC section), the Haynes Nissan Primera 1990–2002 manual, Autodata technical specs, and the Nissan FAST parts catalogue for P11, the 1997 Nissan Primera is fitted with a crank angle sensor. On the petrol GA16DE and SR20DE engines it’s built into the distributor as an optical sensor on the cam, and some variants also use a separate crankshaft position sensor near the bellhousing for misfire monitoring. Bottom line: it’s definitely relevant to this model year.

The crank angle sensor (often called CAS by Nissan) tells the ECU exactly where the engine is in its rotation, so it can fire the spark and inject fuel at the right time. Without a clean signal, the car can be hard to start, run rough, stall at the lights, or throw fault codes like P0335/P0340. Because the 1997 Primera’s petrol engines often house the CAS inside the distributor, issues can show up as “no spark”, intermittent misfire, or random cut-outs when hot.

For servicing, it pays to treat the CAS as a critical electrics item. Check the distributor cap and rotor condition (where fitted), look for oil inside the distributor (a common seal leak that contaminates the optical sensor), and inspect the CAS wiring plug for brittle insulation or green corrosion. If there’s a separate crank sensor on the trans case, make sure its harness isn’t chafed and the mounting face is clean of metal fluff.

If replacement’s on the cards, many owners choose to swap the complete distributor on the petrol engines, as the integrated sensor is tricky to service on its own and a new or quality reman unit restores several components at once. Mark the distributor position before removal to keep base timing close, and finish with a timing check using a scan tool and timing light per the factory procedure. Use OEM or top-shelf aftermarket parts, cheap sensors can give noisy signals and driveability grief.

Other handy tips: keep battery voltage healthy (low volts upset sensor signals), fix any oil leaks early, and avoid pressure-washing directly at the distributor. If the car cranks but won’t fire, or dies when warm then restarts after cooling, don’t rule out the CAS—scan for codes and scope the signal if possible.

• Typical symptoms of a failing CAS: hard starting, random stalling, misfires, rough idle, poor economy, and stored codes P0335/P0340.
• Typical locations: inside the distributor (petrol), plus an additional crank sensor at the bellhousing on some variants.

Popular questions about the 1997 Nissan Primera crank angle sensor

Where is the crank angle sensor on a 1997 Nissan Primera?
On most petrol 1997 Primeras (GA16DE, SR20DE), the crank angle sensor is integrated into the distributor on the end of the camshaft. Some versions also carry a separate crankshaft position sensor mounted at the gearbox bellhousing. If you’ve got the distributor type, you’ll be checking under the bonnet at the end of the cylinder head, the add-on crank sensor sits low near the trans.

What are the signs my crank angle sensor is failing?
Common signs include hard starting, a sudden stall and no restart until it cools, intermittent misfire, rough idle, sluggish performance, and the MIL on with codes like P0335 or P0340. On distributor-equipped cars, oil inside the distributor or moisture ingress can tip the sensor over the edge.

Do I replace just the sensor or the whole distributor?
While it’s sometimes possible to replace just the internal sensor, many owners and workshops opt to replace the complete distributor assembly on petrol models. It’s quicker, solves multiple wear points at once (bearings, cap/rotor, internal wiring), and often proves more reliable long-term. Always follow the factory timing setup after installation.
