Yes, an unplugged sensor can cause a check engine light.
No, it would not. There are many things that could cause a stall at idle. The throttle plate could be dirty as well as the mass air flow sensor. You did not mention the kind of car or engine size. Is the check engine light on, is it when the engine is warmed up or cold?
some OBD 2 systems have a 4 wire 02 sensor if the o2 sensor is bad it will cause a stall, some times a break in a vacuum line will cause the same effect.
Have electronic vehicle speed sensor in transmission checked out. It will cause loss of speedometer function and set a fault code(check engine light).
yes it can but also check the speed sensor if your vehicle is equiped with one.
Yes, a failed O2 sensor can indeed trigger a check engine light. The O2 sensor monitors the oxygen levels in the exhaust and helps the engine control unit (ECU) optimize fuel efficiency and emissions. If the sensor fails or sends incorrect readings, it can lead to poor engine performance and increased emissions, prompting the check engine light to activate. It's advisable to have it diagnosed and replaced if necessary to ensure optimal vehicle performance.
Possible failure of the output/vehicle speed sensor.Possible failure of the output/vehicle speed sensor.
Yes
It is possible.It is possible.
Not likely. A bad O2 sensor would illuminate the check engine light and the engine performance would suffer.
Yes, it is one of many things that can cause the check engine light to come on.
On a vehicle, the check engine light will probably come on. It may also quit or run poorly, depending on the sensor.
