Parts for your 2000 Toyota Corolla-Camshaft sensor

2000 Toyota Corolla camshaft sensor — is it actually used?

For most 2000 Toyota Corolla models sold new in Australia and New Zealand (AE112 with the 7A‑FE 1.8L engine), there isn’t a separate, stand‑alone camshaft position sensor fitted. Instead, the engine uses a distributor that contains the timing pick‑ups (Toyota calls them the NE and G signals) to tell the ECU both crank and cam position. So if someone’s chasing a “camshaft sensor” as a loose part for these cars, it generally isn’t a relevant replacement item — the function lives inside the distributor assembly.

This isn’t just folklore. The Toyota E110 Corolla Repair Manual for the 7A‑FE ignition system shows the NE (crank reference) and G (cam reference) signals coming from the distributor, with no external camshaft sensor. By contrast, Toyota’s New Car Features for the 1ZZ‑FE with VVT‑i, and common service guides like the Haynes Toyota Corolla 1998–2002 manual, detail a dedicated camshaft position sensor on the cylinder head for 1ZZ‑FE engines. Autodata and Toyota’s EPC likewise list a CMP sensor for 1ZZ‑FE, not for the 7A‑FE distributor setup.

Why isn’t a separate camshaft sensor used on the local 7A‑FE? The 7A‑FE of this era runs a distributor‑based ignition and doesn’t use VVT‑i, so the ECU already gets all the cam/crank timing info it needs from the pick‑ups in the distributor. Fewer external sensors, simpler wiring, and proven reliability — very Toyota.

• AU/NZ‑delivered 2000 Corolla AE112 with 7A‑FE: no separate external camshaft sensor, timing signals are inside the distributor.
• Grey‑import or swapped 2000 Corolla with 1ZZ‑FE VVT‑i: does have a stand‑alone camshaft position sensor on the cylinder head.
• 2001‑on ZZE122 (1ZZ‑FE) sold in AU/NZ: stand‑alone camshaft position sensor fitted.

FAQs — 2000 Toyota Corolla camshaft sensor

Does my 2000 Corolla have a camshaft sensor?
Most Aussie and Kiwi 2000 Corollas (AE112, 7A‑FE) don’t have a separate camshaft sensor. If the car has a distributor, that’s where the ECU gets cam and crank signals. If it’s a 1ZZ‑FE VVT‑i engine (often seen on imports or later models), there will be a dedicated sensor on the cylinder head.

Why am I seeing a P0340 camshaft sensor code on my 2000 Corolla?
On a 7A‑FE, P0340 usually points to the distributor’s G signal (cam reference) circuit — think worn distributor pick‑up, wiring, connector corrosion, or ECU ground issues. On a 1ZZ‑FE, it can be the actual camshaft sensor, oil contamination in the sensor bore, damaged wiring, or timing chain stretch affecting cam phase.

Can a faulty distributor pick‑up mimic a bad camshaft sensor?
Yes. On the 7A‑FE, the distributor houses the sensors that provide both crank and cam position. A failing pick‑up, poor shielding, or loose rotor/shaft play can cause no‑start, misfire, or stalling that feels just like a dead cam sensor on newer engines.
