FORD:
1990 PROBE
ISSUE:
The trip computer may display inaccurate average fuel economy and distance to empty information. The calculations may be about 50-75%
higher than actual. This occurs because the trip computer misinterprets the signal from the engine.
ACTION:
Modify the computer circuitry by removing a resistor. Refer to the following procedure for service details.
1. Remove the trip computer display assembly. Refer to the 1990 Probe Shop Manual, Page 33-61-13 for the removal procedure.
2. Position the display assembly on a clean work area.
3. Remove the four (4) screws holding the metal cover. Carefully remove the cover and put the screws in it for use later.
4. Place the display window face down on the work table surface.

5. Locate the first resistor # R212 located to the right of the divider block, Figure 1. The number R212 is printed to the top of the resistor. It is color
coded YELLOW, PURPLE, RED and GOLD.
6. Use a felt tip marker on the resistor to identify it for removal.
7. Use a small X-Acto type knife to remove the resistor from the circuit board.
