1998 Honda Accord LX with engine code P1739

Question

What does this mean and what can happen if I don't fix it asap?

Answer 1

Hi there,

The code stands for a problem with the 3rd clutch pressure switch circuit.

Basically it's seeing an error in the 3rd clutch wiring or solenoid. If not repaired the car will lose 3rd gear. This may also be an issue with the transmission itself or the 3rd clutch in the transmission.

Answer 2

Start by checking the transmission fluid level and condition. If the fluid is OK the next step is replacing the 3rd Clutch Pressure Switch.
