Can a bad cam sensor cause only one cylinder to misfire?
Answer: If the faulty cam sensor has a bad effect on ignition timing (at least in some models), it can lead to a misfire; enough raw fuel will cause the catalytic to get red hot. Question: Would a bad camshaft sensor cause only one cylinder to misfire?
What should the voltage be on a camshaft sensor?
After these checks, use a digital multimeter that can test either alternate current (AC) voltage or direct current (DC) voltage, depending on your particular type of camshaft position sensor. You’ll also need the correct electrical values for your particular type of sensor. You may find this information in your vehicle repair manual.
What to do if your oxygen sensor is bad?
