Any ideas I would greatly appreciate it. All that comes off by removing screws in the door handles. Put it in and fuel gage does not work and low fuel message. It may be like that due to a recent fuel pump replacement and not connected well or it can be something more serious. If the voltage is still high with the sensor unplugged, check the wiring harness for a short to voltage on the signal wire. I don't want to throw parts at it or spend money I don't have to.
Check fuse see owner's manual - check with multimeter and view to see if clearly burned through. Disconnect the sensor and inspect the pins in the terminal to ensure they are clean and moisture free. I pull live problem vehicles directly into my classroom and we troubleshoot them in real time, using and applying the theory and testing procedures we learn during the classroom lectures. My cousin removed the tank to change fuel pump and he is getting ow P0452 code. But I think I have figured it out.
If the voltage spikes or drops off while you are wiggling a section of wire, you likely have a break in the wire that needs to be repaired. The pressure sensor is mounted on the pump unit. A known six thousand year supply of that stuff that could solve all of our energy problems if we had a vehicle that could run on it. Also you need a slim little wrench that takes the window crank off. I guess thats causing the fuel gage to not work. I do not have any leaks and llike I said I can drive all day long as long as the engine temp is below 190 degrees.
The six cylinder base model was offered with a five-speed manual transmission, but the extended cab and other models equipped with an eight-cylinder only included a four-speed automatic transmission; with or without four-wheel drive. First of all make sure your fuel cap is on tight as this may be the cause. Check each side with red…. Lower the tire to access it on 4 door. Wouldn't have these kind of problems with the vehicle sitting in a warm and air conditioned showroom.
Before someone brings it up, I have an extra cluster that I know the fuel gage works. Now I also have code P0463 fuel level sensor circuit high imput. They don't give you a disk when you purchase a vehicle. More than likely a corroded connector, see a lot of that with crap spread all over under the vehicle constantly exposed to road salt along with rusted out brake and fuel lines plus the parking brake cables. You may have to remove loom or electrical tape to inspect the wiring. The distributor will move a little but won't correct major timing errors. That time, just turned on the heat in my garage and left it, code went away on its own.
The control system pressure sensor is not used to control the engine system. Told me that was cheap. If the sensor was reading high voltage and that disappears when the sensor is unplugged, check for proper ground and ensure you have 5-volt reference voltage. Not much different than your home computer with a problem, is it hardware or software causing it to go crazy? I pulled the code and it came up P0452. I think both of them may share some same wiring. It holds pressure in fuel line for about 5 min before it slowly starts to drop. However there is alot of air in the fuel line.
Tried replacing ignition control module, and coil pack. This allows vacuum to b. Check if the clamp is loose or leaks in the tube which can cause an incorrect reading. I drove it for about 5 miles with no issues. So when that damned light comes on, give you a hint to what to look for.
You will likely find it broken or disconnected there. The check engine light was also on. City just opened an assisted home with 62 rooms, claim it cheaper than a nursing home, but have to be well enough to use the rest room and take a shower that is in each room. If it was the sending unit I should have the problem all the time not just when I get over 190 degrees. Refer to for replacement, setup, and programming. Vacuum is consider negative pressure.
When I parked it last night it had a half tank of fuel. Oh yeah, the trucks runs perfect. That is the reason I am asking if there is a. The vehicle in test is a 2002 Chevy Silverado 4. Good luck and hope this helps.
