What is the position sensor bulb light on dash

Clean out the throttle body with fuel injection cleaner then check your vacuum lines if all are good then you should have codes set your check engine light should be on verify that the check engine light bulb is not burned out turn the key to the on position you should see all the dash lights //oil//battery//check engine light if you don't see it the bulb is blown out and if all other things I mentioned are done and the problem is still there either your throttle position sensor is bad or your idle air control valve but I would go to the throttle position sensor first because your car is now 17-18 years old by the door sticker date and if you don't know the repair history because it's a used car check that sensor first if you can get a code scanner from someone/ loaner from autozone you will no for sure

You must clean the fuel injection with fuel injection cleaner and check your vacuum hoses if all is good is your check engine light on? to verify that the bulbs not burned out turn the key to the on position all the dash lights should be on // oil brake check engine if you don't see it on the bulbs burned out there should be codes set go to autozone and have them read if there's none then either your throttle position sensor is bad or the idle air control valve is shot

Hey Joe , the resistor you refer to is actually a light sensitive transistor , an it's called an ambient light sensor ! It is located in the top center of the dash pad , that little round bulb ! To replace it you have to Remove the instrument panel (I/P) trim pad. Are your Daytime Running Lamps (DRL) Inoperative ?

1. Expose the ambient light sensor to a bright incandescent lamp.
2. Turn ON the ignition, with the engine OFF.
3. Place the headlamp switch in the OFF position.
4. Ensure the parking brake is disengaged.
5. Block the wheels.
6. Place the transaxle in NEUTRAL.

Do the daytime running lights (DRL) illuminate?
??????

just on the dash right....... because your dash lights turned on and it changes the brightness of the dash lights, try rolling the little wheel down on the left and see if there is a change?

on the other hand if the outside blinker light fails to work at night the bulb might be burned out you should check it and the dash light might not work if bulb is burned
just turn on the lights turn on the key and blinker and go look?

check for chauffed wiring under dash around steering column and brake pedal, as for your rear brake/side light you have probably put the bulb in the wrong position remove bulb and rotate and retry

For a car that’s over 20 years in age, I would say bulbs need replaced. For the dash though, check the “bright/dim” adjust for the dash lights to make sure it wasn’t turned to the off position.

There is no sensor. The lamp module monitors bulbs. Check the connector on the rear bulb carrier. The ground wires like to corrode and melt the plastic.

check your cam and crank sensors

The relay has nothing to do with the tail lights, but replacing the switch sounds like a good idea. There's a nut holding it in place, see http://www.skandix.de/en/spare-parts/electrics/switches/switch-headlight/1027524/ to get an idea of the construction. And the price. This is not worth fiddling about unreliable workarounds...
In addition, if fuses 15 and/or 16 burn frequently there might be a problem with the tail light cabling.

Good luck

I believe the parking lights are the lights that come on when you move the headlight switch to the middle setting. My S60 has 3 settings for headlights, daytime running lights (off or 9 o clock position), parking light (middle or 10:30 position), and lights on (top or 12 o clock position). Put your light switch into the middle position and check the lights from the front of you car. They are usually located on the side of the headlights and are orange. If the fault is on, you have a bulb out (most likely) or loose wire connection (not as likely).
