Could be the idling sensor or the EGR Valve
It could be that your car is idling to low, the throttle position sensor can be bad
A bad coolant temperature sensor is one thing that could cause an idling speed problem with a Peugeot 406. There could also be a problem with the idle control valve.
The throttle position sensor (tps) could make the rpms vary.
Mapp sensor or you might need pugs and wires.
Depending on the vehicle the sensor could be located in several places. It is usually on the side or rear of the transmission, and either bolts on or screws in.
Depending on the vehicle, a faulty VSS (Vehicle Speed Sensor) could affect the automatic transmission shift points.
Yes, it could.Yes, it could.
You have a bad Vss Sensor.............. The vehicle speed sensor.
Could be an exhaust leak close to the engine or a bad catalytic converter. It also could be a bad mass airflow sensor.
That problem is very popular believe it or not even in my 1998 model. I was told that it could be an oxygen sensor or a mass air flow sensor. If you are experiencing idling problems where your vehicle cuts off while you are completely stopped or when turning corners then you may possibly need to check the throttle body. It can get pretty cruddy inside and the vehicle has problems breathing.
Perhaps clutch throw-out bearing?
