Knock sensor



The low level of the input signal chain knock sensor (P0327)
The PCM monitors the input signal is the knock sensor with the engine running. If the input voltage between 2P and 2S unit PCM - below 0.9 V, the PCM determines that the knock sensor circuit has a malfunction.

The high level of the input signal chain knock sensor (P0328)
The PCM monitors the input signal is the knock sensor with the engine running. If the input voltage between 2P and 2S unit PCM - above 4.9 V, the PCM determines that the knock sensor circuit has a malfunction.

Sensor Circuit Malfunction crankshaft position (P0335)
If the unit does not receive a PCM input voltage from the crankshaft position sensor during 4.2 s, while the air mass flow rate is 2.0 g / sec or more, the PCM determines that the crankshaft position sensor circuit has a malfunction.

Circuit Fault camshaft position sensor (P0340)
The PCM monitors the voltage of the camshaft position sensor when the engine is running. If the unit does not receive a PCM input voltage from the camshaft position sensor, while the input signal of the crankshaft position sensor is present, it decides that the camshaft has a circuit failure.
