1991 Honda Prelude Problems
RepairPal has identified the most common problems with the 1991 Honda Prelude based on complaints from actual vehicle owners. We'll tell you what the problem is and what it'll take to fix it.
The 1990-2001 Honda Prelude engine oil pressure sensor is known to leak from normal operation.
More information about the oil pressure sensor here.
To correct the leak, the sensor must be inspected, properly sealed and installed, or replaced with new.
The 1990-1992 Honda Prelude commonly has mechanical issues with the manual transaxle.
Drivers will notice that upon decelerating, the transmission will shift to neutral on its own, and some gears, normally second, will be difficult or impossible to select with the gear selector. Lastly, a grinding noise accompanies these issues. It changes with engine speed, and comes from the transmission.
The engine connects to the transmission with a clutch and shaft. The clutch engages or disengages the transmission input shaft, and the transmission input shaft drives the transmission. The input shaft is held in place by bearings which allow it to spin. When those bearings fail, the input shaft can move, and the problems noted above become very evident due to the loss of synchronization of the transmission.
To correct the situation, the transmission must be removed from the vehicle, disassembled, rebuilt, and reinstalled in the vehicle.
The best way to ensure this doesn’t happen to you is proper maintenance of the transmission.
The front brake rotors can warp and cause a vibration when braking. The rotors will need to be machined or in cases where they are worn to thin, replaced to correct this issue.
On some models a jingling noise from the rear can be heard due to uninsulated damper mounts. Both rear damper mounts will need to be insulated to quiet the noise.
A front bearing failure in the alternator can cause a whining type noise in the engine area. Replacing the faulty bearing or the alternator will repair the problem.
