⚡ Fault Code: P0340  |  Camshaft Position Sensor Circuit  |  Bank 1

If you’re in Loughton and your scanner is showing P0340, your car’s ECU has lost a reliable signal from the camshaft position sensor circuit — and that’s why you’re getting a long crank, a no-start, or an unexpected stall. The code points to a circuit fault, not necessarily a dead sensor: wiring damage, a corroded connector, timing chain stretch, or a rare ECU issue can all trigger the same code. At MnF Motors we test the circuit properly before touching any parts. Diagnosis starts from £55 and most sensor or wiring repairs are completed same day. Call 020 8803 1231 to book.
