my cars check engine light when on, code p0340 the camshaft code.... its been running rough, it jerks on first gear, sometimes the transmissions feels harder, and occasionally it takes 2-3 tries to turn on. Anyways I bought a sensor on A1 auto and I installed it but the car cranked but did not start with the new sensor. I put the old OEM sensor back in and it started fine. did I not install the sensor right? could the part be defective? I did not lubricate the new sensor when I inserted it.
