SOURCE: Speedometer - 40MPH

the speedo is electronic, not cable, this problem is caused by a sticking stepper motor that moves the needle, a stepper motor is a miniature electric motor that can move and hold one position, this was a common problem at the dealer I worked at, u will need to pull the speedo and send it out for repair, I use the following link for this service.

SOURCE: speedometer malfunction

Possibly stripped the plastic gear at the transmission case where the speedometer cable enters. You can unscrew the cable from the transmission case and the gear should be sitting right there. Pop it out and see if the gear threads are stripped.

pull the cluster out and check for a loose connection at the rear, check the guage fuse for a poor connection in the fuse box, if you have a Body control module that is a p[ossibilty as well.

Actually located a local mechanic that used to work for GM to install it. Thank you.

My guages stoped working and transmition seems to be slipping in my 2001 shevy silverado 4.8


Well ronnie do you know how to do automotive electrical testing with a volt meter ? How to read an understand a wiring diagram ? Would think not to be a relay problem because other thing's would not work as well ! More then likely a loose ground or something on that order ! Plus you must mean Ignition . 1 relay , because there isn't a eng.1 relay . Ign. 1 relay powers the PCM - engine computer , fuel injectors , the TAC - electronic throttle control module . Do the instrument cluster lights still work when the gauges quit ? Looking at power distribution diagram I see a engine 1 fuse but has nothing to do with the instrument cluster . Supply's B+ voltage to the maf sensor , EVAP system , CAM sensor , IAT sensor , fuel pump relay ! Could be a communication problem on class 2 data bus . All the modules on the vehicle share information on the class 2 bus . The gauges get thier info from the PCM over this data network !
Engine Coolant Temperature Gauge
The IPC displays the engine coolant temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the engine coolant temperature. The engine coolant temperature gauge defaults to 75°C (160°F) or below when:
• The PCM detects a malfunction in the engine coolant temperature sensor circuit.
• The IPC detects a loss of class 2 communication with the PCM.

Fuel Gauge
The IPC displays the fuel level as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the fuel level percent. The fuel gauge defaults to empty if:
• The PCM detects a malfunction in the fuel level sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.
Reviewing the fuel system description will further explain how the system functions. Refer to:

Speedometer
The IPC displays the vehicle speed based on the vehicle speed signal from the PCM. The IPC receives the vehicle speed signal via a discreet wire. The IPC uses the vehicle speed signal circuit (4000 pulses/mile) from the PCM in order to calculate the vehicle speed. The speedometer defaults to 0 km/h (0 mph) if a malfunction in the vehicle speed signal circuit (4000 pulses/mile) exists.

Tachometer
The IPC displays the engine speed based on the engine speed signal from the PCM. The IPC receives the engine speed signal from the PCM via a discreet wire. The IPC uses the engine speed signal circuit (2 pulses/engine revolution) from the PCM in order to calculate the engine speed. The tachometer defaults to 0 rpm if a malfunction in the engine speed signal circuit (2 pulses/engine revolution) exists.
Transmission Temperature Gauge
The IPC displays the transmission temperature as determined by the PCM. The IPC receives a class 2 message from the PCM indicating the transmission temperature. The transmission temperature gauge will default to 40°C (100°F) or below if:
• The PCM detects a malfunction in the transmission temperature sensor circuit.
• The IPC detects a loss of class 2 communications with the PCM.
Voltmeter
The IPC displays the system voltage as detected at the ignition 1 input of the IPC. When the engine is ON, the gauge should be between 10 and 16 volts.

The only one that has a hard wired sensor is the oil pressure gauge.
Engine Oil Pressure Gauge
The IPC uses the engine oil sensor signal to determine the engine oil pressure. The oil pressure sensor signal circuit is hard-wired to the IPC. The engine oil pressure sensor signal to the IPC is a variable resistance ranging from 0-90 ohms. A sensor resistance of 1 ohms will display as 0 psi (0 kPa) and a resistance of 88 ohms will display as 80 psi (550 kPa). The Check Engine Oil Pressure indicator will be displayed in the message center if the IPC detects a low engine oil pressure.

Does this one drop out also ? quit working

I would suggest that you take an have the IPC checked for DTC'S - diagnostic trouble codes , NOT OBD 2 engine codes , these are different an need a professional type scan tool .
You could check G103 for being loose . G103
On the left rear of the engine block . Also pull the instrument cluster out an check connection at the back of IPC . Check power an ground circuits at the PCM as well . You can fine wiring diagrams here
http://www.bbbind.com/free_tsb.html Enter the vehicle info . year , make , model an engine . under system click body an acc. then under subsystem click on instrumentation .Click the search button , then click the blue link . At the top of the diagram it shows B+ power supply , The connectors on the back of IPC , A,B , plus the pin # an color wire .

Guages not working,


If all voltages checked ok,then most probably its faulty instrument cluster board on which gauges are connected.Yes if cluster circuit board looks ok,then also it can be faulty.Somewhere there is minute short or burn on board then such prolem arises.
Also check the fuse box.One under hood and other under dash.Inspect each and every fuse and see if all are fine or not.

Gas gague not working in 93 gmc sierra


The fuel level gage sending unit is defective, very common problem. The sending unit comes with a new fuel pump and is referred to as a module, also make darn sure you replace the fuel pump connector at the fuel tank, solder and shrink tube the new connector on, DO NOT USE CRIMP CONNECTORS.

Temperature gauge, fuel gauge and speedometer not functioning correctly , temp gauge states overheating , speedometer does not register proper sped , fuel gauge always says empty


Faulty instrument cluster. GM has had many problems with their instrument clusters and this is one of them.There has been a recall untold,that if your vehicle is not over 7 years old and have less than 70,000 miles on it they will replace it at no charge.GOOD LUCK!! P.S. if they won't cover it then you can get one at www.Dorman.com .

Dashbord instrumentation Non functional for Japan imported FB14 Sentra


VOLTAGE REGULATOR
Located behind the instrument cluster
It is attached to the rear panel of the cluster.
input from battery is 10Volts, it regulates down to 5Volts
Any higher voltage inputed will overload the capacitors and resistors will burn,
Also check power distribution center, under hood upper motor area in drivers corner, check all relays and fuses.
Before you rip in to the dash check all ground wires, battery to ground, harness grounds, driver/passenger mid fram rail, Fuel sender is also ground to top of gas tank. IF ALL gauges do not work, that just leaves voltage regulator and/or cluster is malfunction,
