What can you check or replace if the check engine light comes back on and the code is P401 and you have already replaced the EGR valve?
Check the EGR selenoid valve. The vacuum will pass throught the defective selenoid valve and go the EGR valve even if it has not been activated. The ECM will not detect a defective selenoid valve - only an EGR problem.DPFE sensorIf it's a Ford product, you may need a DPFE sensor. You should also check for a restriction in the EGR passageway.
What is the car selenoid?
There are many solenoids in a car, fuel injectors, egr are some.
My selenoid keeps burning out on 1987 f-150?
i connect all the wires the way i took them off the old selenoid and the starter selenoid and wires keep gettin hot and has burnt out the selenoid,replaced starter had the truck running fine shut it off and went to start it and the selenoid melted
What is this code 32 Fault in EGR diagnostics 1996 neon do you replace egr or just the sensor?
It is always recommended that the valve and sensor be replaced together. When I replaced my EGR system this is what I did. My guess would be each selenoid and valve are calibrated together as a unit, however I do not know this for certain since I have never used an old selenoid with a new valve or vice versa. Typically you know the selenoid is shot when the engine light comes on but the car seems to operate just fine. You know the valve is shot when the car starts to idle like crap, which means the valve is sticking open at idle speed, which means some sort of mechanical failure within the valve itself. Sometimes taking the valve off and cleaning it works rather than replacing the whole setup. Hope this helps good luck!
How do you know if a starter solenoid on a riding mower is bad?
First you check to see if the selenoid is working by turning the ignition key and listen for a click on the selenoid if you hear a click the selenoid is probably working. Then you take a test light and put it on one side of the large wire which should have power if you turn the key on. If you have no power on either side your trouble is before the selenoid. If you have power on one side but not the other when you hear the click of the selenoid, when you turn the key on, your selenoid is not working.
Where is the selenoid located 2000?
On top of the starter.(usually)
What is the clunking noise in your 2004 ford escape after you put it in four wheel drive?
A selenoid is activated from the rotary switch on the dash. This selenoid engages the AWD system causing the slight clunk
How do you adjust the cylinder timing on a fiero?
you cannot adjust the iddle on a 84 fiero. the iddle control is made by the computer. there is a air control selenoid on the left of the throttle body. the selenoid controle the iddle air flow. to make sure the selenoid is working properly, you can remove the air boll and filter so you can see the point if the selenoid. when the engine is passing from high revolution to iddle, the selenoid will move. if it moves it is probably in good working condition. if the iddle of the engine is too high, you might have a vacumm leek somewhere. check all the vacumm hoses for proper working condition.
Where do you find the starter selenoid in a 85 delta 88?
connected to the starter
1997 F150 XLT won't start makes a click when you turn the key In past with cleaning on battery terminal it would start but not this time Is it starter ignition switch selenoid starter relay other?
Sounds like starter selenoid or the starter cable going to the stsrter needs to be taken off and cleaned and the inner nut on the selenoid may not be torqued properly.
Why 1996 camaro won't start has no power to starter ignition switch is good?
1. bad starter selenoid 2. blown fuse in the circuit 3. bad ground at the starter (not likely, but possible) Start at the starter, with a test light, and work your way back through the curcuit until you find power. That's where the problem will be. If the starter has no power move to the selenoid. If the selenoid had no power in the switch circuit move to the fuse. If the selenoid has no power on the battery side move to the fusable link. Keep working your way to the ignition switch.
Is there a fuse on a craftsman riding mower?
It is typically close to the selenoid. It is inline with the wiring.
