A guide to problems, costs, maintenance and repair for your 1994 Mercury Topaz

1994 Mercury Topaz Problems

The vehicle may lose vehicle speed signal, which can affect speedometer operation and transmission shift quality. Most often the Vehicle Speed Sensor is faulty, however, at times, the driven gear inside the transmission is at fault. Replace the Vehicle Speed sensor and inspect the driven gear upon sensor removal.

Poor rubber material used in the motor mounts can cause them to fail, leading to a knocking noise or lifting sensation on acceleration. The motor mounts will need to be replaced with revised parts.

Fuel pump failure can cause the engine to crank but fail to start. Diagnosis will show insufficient, or no fuel pressure, and fuel pump in the fuel tank will need to be replaced.

1994 Mercury Topaz Recalls

Ford has recalled certain 1992-1995 Taurus and Mercury Sable models with 3.8L engines, 1994-1995 Taurus and Mercury Sable models with 3.0L engines, 1992-1994 Tempo and Mercury Topaz models with 3.0L engines, 1994 Tempo and Mercury Topaz models with 2.3L engines, and 1992-1994 Lincoln Continental models in certain cold weather states for an issue with the engine electric cooling fan. During high winds, low temperatures, and drifting snow, the fan could become blocked or frozen with snow. This could cause the fan not to rotate and ultimately overheat. Dealers will install a harness with a circuit breaker to protect the fan motor from overheating.
