Gauge cluster reset
i had to remove the needles on the instrument cluster to put the face plate on and i put the needles back on but i did not mark or take a photo ofvthe placement of the needles before i removed them, i put all the needles back on but none of it is reading correctly. is there a way i can reset my instrument cluster so that all the needles read correctly ?
Tach: You should know what your idle RPM is - Set this at idle.
Gas: Fill Tank - Set to full.
Battery: Measure Voltage at Battery with engine ON - Set needle.
Coolant: Get engine up to temperature. Run for 5-10 more minutes - Set needle do the 12 o'clock position.
Oil Pressure: This is is going to be a bit of a guess if you don't know where your needle usually was or have a scanner - Setting to the 10 or 12 o'clock position is an OK guess.
^ An OBD II scanner that will give you these values from the PCM would give you perfect readings.

That's what I was going to suggest. Had a buddy of mine replace all his stepper motors in his silverado and he somehow messed up his needle placement. Pulled up all the PID's and set it, took a few tries with the speedo but nothing too difficult.

We've just given you methods to come up with approximations. So, the needles could be off, and lying to you a bit - but you'd never know. (Unless you have an OBDII scanner, you won't be precise, across the board.)
Using a reliable GPS unit to calibrate the speedo is probably the most critical thing, so that doesn't get you pulled over.

if I did then would i be asking how to reset my gauges?no!and as far as lying to me you can keep your commensto yourself and let a knowlegleble person answer.
ps work on your attitude, you'll catch more flys with honey.
BTW, there are advanced procedures to set the gauge needles but they involve special equipment such as a scan tool and a signal generator. For example, the oil pressure gauge should read low, 30psi, and high at resistances of 0 ohms, 40 ohms and 100 ohms respectively. Similarly, the fuel gauge will go from empty at 40 ohms to full at 250 ohms.

I was saying the gagues will be lying to you if you take the route of approximations and reinforcing what biketopia was emphasizing. (This may not be a big deal to you - much can be said about the accuracy of the gauges and the sensors in the car to begin with.)
However; if you really want to have the all gagues read "properly", then you have to get a hold of an OBD II scanner that provides the real-time data from the PCM. (As WhiteBird00 also points out, above.)
Otherwise; you are just approximating. (Using the methods we posted above.) If you approximate, you should at least get a device that will allow you to get your speedometer accurate. If you get pulled over, the police won't care if your needles moved.
