Question about Chevrolet C1500

Open Question

I want to add aftermarket gauges to my 93 chevy 1500 5.7l and need wiring diagram and need ohms for fuel sending unit.

Im wanting to install after market electric gauges on my 93 fullsize chevy 1500 5.7L and need wiring diagram to do so of the gauge cluster so anyhelp would be great and also what ohm is the fuel sending unit?

SOURCE: I have a Dodge Stratus 2004. It has 2.7 L - 6

I will post these one at a time...

Basically this means that an oxygen sensor in bank 1 detected a lean condition (too much oxygen in the exhaust). On V6/V8/V10 engines, Bank 1 is the side of the engine that has cylinder #1.
Note: This DTC is very similar to P0174, and in fact your vehicle may show both codes at the same time.

You will more than likely not notice any drivability problems, although there may be symptoms such as a lack of power, detonation (spark knock), and/or a hesitation/surge on acceleration.

A code P0171 may mean that one or more of the following has happened:

  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor.
Possible solutions include:
  • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure

SOURCE: i want to install and aftermarket fuel gauge

I'm working on the same issue with an 01 Jimmy. Went to parts store and they pulled one off the shelf. I measured the new one with an ohm meter 38 ohms full, 247 ohms empty.

Took the guess work out of what the readings should be, other GM makes & models have different resistance, I would assume *** products might be the same. Parts stores are fairly easy to work with and should let you make a measurement of a new one for reference

It is ok for your gauge to go to 1/4 when off. It is even some what normal. The gauge is going to its neutral position. Keep in mind it is also comon for the sending unit to fail in this year / make of vehicle.

I hope this helps.

look for a short in the sending wiring, empty means the circuit is closed, open circuit full

SOURCE: speedometer not working all gauges work 700r4

Is the speed sensor that you are using the original one, or is it from the Camaro, or is it new for an 89 K1500?

The worm gear inside of the transmission on the output shaft that drives the speed sensor gear is not damaged?

No matter what speed sensor is installed the speedometer still reads the same?

1970 chevy nova gas gauge problen

Well friend, you know the dash gage is good cause that was a proper test procedure. Since your not getting proper readings it has to be the sending unit. Pull it apart and clean the rheostat with a pencil eracer and light pressure, the assemble it and try it again. if still nfg, replace the sending unit. they're cheap from any auto parts store.

Do you have a wiring diagram for the gas gauge on a 1987 chevy r1o pickup truck

I don't have a diagram but I can tell you the pink wire going into the tank should be the sending unit for the gauge.

Gas gauge don't work. says it's full all the time. new sending unit,gastank,fuelpump, and fuel fiter.

I don't have the specs on your dash gauge. You would want to run an OHMmeter to test resistence at the dash gauge, then check the Ohms at the wiring from the fuel sending unit. The change in the Ohms from the fuel tank is what moves the dash gauge.

Best I can help with is a chassis diagram at, FREE, when you register your car.

You can go to a Salvage yard with an Ohmmeter and test a fuel gauge on-the-car to see if it has different resistance. This would indicate whether your gauge is good or not.

Faulty gas gauge

Most of the time its is the sending unit in the fuel tank. The test for it is to use a variable resistor that is hooked up to the wiring at the fuel tank and watch the fuel gauge if the gauge works ok thats makes 100% sure its the sending unit. At 245 ohms the gauge should read full, 180 ohms for 3/4 full, 160 ohms for 1/2 tank, 100 ohms for 1/4 tank and 42 ohms for empty. The color of wires at the fuel tank is purple wire and black wire. You can also use fixed value resisters. If the fuel gauge the wires from the sending unit to computer then to gauge for bad connections, shorts, broken wire and bad grounds. If the wires test ok that only leaves insterrment cluster or computer which even most dealers can't test eather one but the insterment cluster would be a more common problem then the computer. But about 95% of the time it will be the fuel level sensor in the gas tank that causes the problem. Good luck.

I have a 1976 chevy chyenne super , and my problem is that my gas gage always jumps to over full every time I start my truck and I don't know where to start testing or how to start testing possible ways...

If you understand resistance in ohms, and you have an ohm meter you can test out the fuel gauge system. The gas gauge is essentially an ohm meter, and the fuel level sending unit is a variable resistor. as the tank becomes lower and lower on fuel, a float in the tank attached to a variable resistor sends a signal to the gas gauge, and that is how the gauge keeps track of the fuel level. Normally if the gauge pegs out when you start the engine, the sending unit in the fuel tank is bad, or the wire going to the tank has a bad connection. If you remove the sending unit you can check it with an ohm meter. A good repair manual available at most major auto parts stores will walk you through the procedure.

1984 FIERO 4 CYL STICK. had a aftermarket elec temp gauge mounted on console, replaced with a mech temp gauge. after replacing temp gauge is when the fuel gauge messed up. now when you turn on the key or...

I assume you replaced the temperature sending unit when you installed the aftermarket gauge? You need to put the proper sending unit back in for the OEM gauge to work.

You can find a sending unit here (and a gauge if needed):

Hope this helps

Need to attach new electric temp. switch/sensor where aftermarket mechanical one is installed

The factory wire to the factory gauge is a solid green wire. that year truck the sending unit usually mounted in the drivers side cylinder head but i have seen some in the passanger side if they have cut the wire and you can goto the main harness connector under the brake master cylinder and booster and find the only solid dark green wire and follow it forward to see how far it back they cut then just splice and run it to your new sending unit . If you want to check to make sure the gauge works after you find the solid green wire put it to a ground and the gauge should go to hot if it does not you have a bad gauge or a cluster wireing in side the truck and that is why they put the aftermarket gauge in .

It could be a couple of things it could be your sending unit. a bad wire. or possibly the gauge its self. but the bad thing is you have to take your gas tank down to check the wires and sending unit. if you take the tank off you can pull out the fuel pump and sending unit and use a ohm meter to see if the sending unit is reading all the ranges correctly hope this helps you out

1985 t-bird, fuel gauge constantly reads full

I really doubt it is the fuel gage. You can test the gage by hooking a C cell battery to the wires from the tank. If it pegs the gage is good. You will need to go to Ford to get the sending unit. I doubt they will have this in stock, but they will order it for you. I would not even consider an aftermarket sending unit. Stick to the original Ford part. You will be happier with the results.
