What does an EGR valve position sensor do?
The EGR Position sensor detects the movement and position of the EGR valve pintle. The EGR Pressure sensor detects exhaust gas flow through the EGR passage.
Where is the EGR valve position sensor?
Mechanical EGR valve position sensors are mounted on the top of the EGR valve. EGR pressure sensors will be located close to the EGR valve as the exhaust gas hose must be connected to the sensor as well as the valve.
Does the EGR have a sensor?
The EGR position sensor detects the movement and position of the exhaust gas recirculation (EGR) valve pintle. The EGR pressure sensor detects exhaust gas flow through the EGR passage.
What type of sensor is made into the EGR valve?
Digital EGR valves feature a solenoid or stepper motor and, in most cases, a feedback sensor. These valves receive a pulse width modulated signal from the ECU, to regulate exhaust gas flow.
What are the symptoms of a faulty EGR valve?
Bad EGR Valve Symptoms
- Check Engine Light. There’s tons of sensor monitoring your emissions, engine performance, and even the EGR valve’s performance.
- Increased Emissions.
- Decreased Fuel Consumption.
- Reduced Power.
- Rough Idle.
- Engine Knock.
How much is an EGR sensor?
The average cost of replacing the EGR valve in your vehicle is anywhere from $250 to $350 on average, depending on your vehicle’s year, make, and model as well as the type of system it has. The cost of parts will be somewhere around $190 to $270, while the cost of labor will be anywhere from $60 to $80.
Can you bypass an EGR valve?
There are several options available to you when it comes to the EGR valve. You can replace the valve with a new one. You can clean your valve with carb cleaner and refit it. Or, you can blank or bypass the valve completely.
What can happen if EGR valve gets stuck in open position?
Symptoms of an EGR valve that is stuck open include rough unstable idle and stalling. Often a car stalls when stopping after exiting the highway. If the EGR system is clogged up, or the valve is stuck closed, the combustion temperature increases.
Can I unplug my EGR?
If you drive the car long enough to reach full operating temp – THEN pull over unplug the EGR it will not give you a code until the next time you start the car. This is a good way to test the EGR because the with and without comparison is immediate.
