Very likely as the BCM controls the electronic components in a vehicle, but it's worth checking the fuse box under the hood , i noticed you said you had checked the fuse's but the under hood one's tend to get forgotten

SOURCE: Fuel and Temp Gauge go on and off intermitently

faulty wiring for the lights, and blinkers....

broken gears for the fuel and temp gauge...

just get rid of the damn car, get a Civic of the same year.

I was given a 323 once, unsiezed the rear brakes (the idiot left the thing parked with the e-brake on all winter), then sold it for beer money.

SOURCE: Temp gage, fuel gage and dash lights out

yes it is the instrumentation voltage regulator (IFV) I have had to replace twice, it causes the fuel and temp gauge to fall to 0. It is in back of instrumentation cluster on left side about a 1"x1"x1/4", and cost about $50 from dealer.

SOURCE: peugeot speedo mileage counter and speedo dont

Had this problem on mine & the main dealer were stumped. Eventually found it myself after a lot of pocking about.Have a look at the wiring loom in the engine compartment. Looking under the bonnet look closely on the right hand side of the engine above the gearbox where the wiring loom passes from the rear of the engine over a metal bracket/support to the front. The loom has a tendancy to rub against the bracket and eventually damage the cables within. You will have to remove the air filter canistor & a few air hoses to get to the bracket. Good luck!

2002 chevy malibu cranks wont start. fuel and temp gauge dont work. radio reads cal


Cranks won't start , Did you check for spark ,fuel pressure ?
Radio Setup .Will the vehicle communicate with a scan tool ? Fuel an temp gauges not working are probably bad step motors inside the instrument cluster that controls the gauges . Where do the gauges read 0 or something else ?
Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the PCM. The body control module (BCM) receives a class 2 message from the PCM indicating the engine coolant temperature. The BCM converts the engine coolant temperature into a percent gage deflection. The IPC receives a message from the BCM via the serial peripheral interface (SPI) indicating the requested gage position. The engine coolant temperature gage defaults to 38°C (100°F) or below if:
?€¢
The PCM detects a malfunction in the engine coolant temperature sensor circuit.


?€¢
The BCM detects a loss of class 2 communications with the PCM.


?€¢
The IPC detects a loss of SPI communications with the BCM.

Fuel Gage
The IPC displays the fuel level as determined by the PCM. The body control module (BCM) receives a class 2 message from the PCM indicating the fuel level percent. The BCM converts the fuel level percent into a percent gage deflection. The IPC receives a message from the BCM via the serial peripheral interface (SPI) indicating the requested gage position. The fuel gage defaults to E (empty) if:
?€¢
The PCM detects a malfunction in the fuel level sensor circuit.


?€¢
The BCM detects a loss of class 2 communications with the PCM.


?€¢
The IPC detects a loss of SPI communications with the BCM.

When the fuel level is less than a pre-determined value, the low fuel indicator illuminates.
DTC P0462
The fuel level sensor changes resistance based on fuel level. The PCM monitors the signal circuit of the fuel level sensor in order to determine fuel level. When the fuel tank is full, the sensor resistance is high and the PCM senses a high signal voltage. When the fuel tank is empty, the sensor resistance is low and the PCM senses a low signal voltage. The PCM uses the signal circuit of the fuel level sensor in order to calculate the total remaining fuel in the tank. The PCM sends the fuel level percent via the class 2 serial data circuit to the body control module (BCM). The BCM converts this data and sends a fuel gage percent deflection to the IPC via the serial peripheral interface (SPI) in order to control the fuel gage. The fuel level information is also used for misfire and EVAP diagnostics.

Have
For the DE 100 series radio, complete the following procedure, using a scan tool, in order to properly set up communication:

  1. At the Main Menu screen, select: Diagnostics.
  2. At the Vehicle Identification screen, select the following options:
  3. ?€¢
    Model Year


    ?€¢
    Passenger Car

  4. At the System Selection Menu screen, select: Body.
  5. At the Vehicle Identification screen, select the Platform type.
  6. At the Body screen, select: Radio.
  7. At the Radio screen, select: Special Functions.
  8. At the Special Functions screen, select: Radio Setup.
  9. At the Radio Setup screen, press ENTER. The following test will set up a new or existing radio.
  10. Select one of the following options:
  11. ?€¢
    USA/Canada


    ?€¢
    Export

  12. Press the ENTER key.
  13. Verify that the scan tool displays "Test in Progress."
  14. Verify that the scan tool displays "Test Completed Successfully."
  15. Press EXIT on the scan tool.
Important: The radio set up will configure the following systems:
?€¢
LEARN VIN


?€¢
Diagnostic Trouble Codes


?€¢
Class 2 Radio Messages


?€¢
Country Code


?€¢
Chime Volume


?€¢
Chime Level


?€¢
12/24 Hour Clock

Without learning the VIN, the radio will display a locked message (LOC).
The radio setup procedure will also clear the following messages:
?€¢
CAL


?€¢
CAL ERR


?€¢
CALIBRATE

Where is the tempature guage sensor


The temperature gauge sensor as you call is for more then just the temperature gauge . The temp. sensor is an input to the PCM -engine computer ! If it were bad you would have drivability problems , the transmission would not shift correctly an the check engine light would more then likely be lit .
Engine Coolant Temperature Gage
The IPC displays the engine coolant temperature as determined by the PCM. The body control module (BCM) receives a class 2 message from the PCM indicating the engine coolant temperature. The BCM converts the engine coolant temperature into a percent gage deflection. The IPC receives a message from the BCM via the serial peripheral interface (SPI) indicating the requested gage position. The engine coolant temperature gage defaults to 38?°C (100?°F) or below if:
?€¢
The PCM detects a malfunction in the engine coolant temperature sensor circuit.


?€¢
The BCM detects a loss of class 2 communications with the PCM.


?€¢
The IPC detects a loss of SPI communications with the BCM.


Your gauge is more suspect then the sensor . gm had a problem with stepper motors that control the pointer for the gauge !

Good day, I need a wiring diagram for the instrument cluster on a 2001 Mazda B2500 TD with the plug pin labelling in pdf format.


The only place I know of to view the wiring diagram is in the workshop manual . Your friendly sparky may print out the page for you. If not invest in the manual, you will save the price on the first repair.
