    Toyota error code

    Light went off, but would periodically go on for 20 miles or so. This code may appear in combination with related codes P0340 and P0341, which both indicate intermittent electrical circuit problems with CMP sensors unable to send signal to indicate that the crankshaft sensor signal is correct. Second opinion] Toyota SCION tc stick shift, I have the code : P0012Timing is perfect and sensors are change, camshaft pos sensor, crankshaft sensor to also computer was changeAnd re - programmedV. However, if the P0420 code is the only trouble code - or if the other codes are all P042X codes - the likelihood of a failed catalytic converter is much higher. Several things can cause a P0420 code in a Toyota:. HINT: Factors such as instrument type may cause readings to differ slightly from stated values. If any DTCs are displayed during a check mode DTC check, check the circuit for the DTCs listed in the table below. The P0430 check engine light code, like P0420, means the catalyst system efficiency is below the required threshold. Here' s how to fix the problem.

There was an issue with this engine with the cam chain tensioner - which also affects cam timing, and could set a P0340. The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module( ECM) to control ignition and fuel injection. What Does P0340 Code Mean? OBD- II Code P0340 is defined as a Camshaft Position Sensor " A" Circuit Malfunction The Camshaft Position Sensor measures the exact rotational position of the camshaft. This provides a critical data signal used by the Powertrain Control Module ( PCM) to control Ignition. HINT: Parameters listed in the chart may be different than your readings depending on the type of instrument and other factors. Hi, I have a 97 Toyota Celica 2. 2L MT and I am getting a P0340 engine code: ( P0340 code indicates that a problem was detected in the camshaft position sensor circuit) but this year does not have a cam.

    DTC P0717 is for a transmission input turbine shaft speed. P0340 Toyota Description The Camshaft Position Sensor is an electronic device used in an engine to record the rate at which the camshaft is spinning. This information is used by the Engine Control Module( ECM ) to control ignition and fuel injection. Detailed information on troubleshooting and repairing a p0335 automotive trouble code which refers to a malfunction in the crankshaft position sensor. Also includes links to relevant forum topics on the code. What P0340 really means: The sensor measures how fast the camshaft rotates, and the position of the camshaft in the rotation. This information is used by the on board computer to initiate fuel injector spray, and in conjunction with the crankshaft position sensor to determine ignition timing. Until I got the P0340 code yesterday I suspected that it was a faulty MAF sensor that was causing the problem.
