CAN obd2 Check spark plugs?
Most engine control systems with OBD II monitor the speed of the crankshaft between cylinder firings to detect misfires. fire problem may continue unnoticed and undiagnosed until the vehicle fails a tailpipe emissions test, or until the spark plugs are replaced and suddenly the engine runs like new again.
Will a bad spark plug show a code?
Bad spark plugs can cause your engine to misfire. The engine’s computer uses sensors to detect these misfires and will create a code that turns on the check engine light. A flashing check engine light indicates the misfire is severe enough to cause damage to your catalytic converter.
What causes a PT Cruiser to misfire at idle?
If a coil pack goes bad, it’ll cause a misfire and rough idle condition. Really, your PT Cruiser will be running rougher at any RPM, but a misfire will be most pronounced at idle.
What are the oxygen sensors on a PT Cruiser?
The oxygen sensors that are equipped in your Chrysler PT Cruiser are responsible for monitoring the exhaust to help the ECU determine the correct air/fuel mixture. Of all the sensors equipped in your vehicle, the O2 sensors may have it the hardest. They deal with super hot exhaust that can cover them in deposits that can leave them ineffective.

Can a faulty spark plug cause a faulty ECU?
If signal is faulty – ECU must be working in safe mode. That is why your check engine lamp was light on. But if you have bad high voltage wires (plugs – coil) then high voltage jumps through any weak points and can damage and even solder parts. It also can damage ECU and its electronic parts like condensers.
