Code P1768 1998 Honda Civic Description

The A/T clutch pressure control solenoid valve is used for shift control and lock-up control. A spool in the A/T clutch pressure control solenoid valve pushes a valve according to the duty cycle that is controlled by the Powertrain Control Module (PCM) to pressurize fluid so the hydraulic pressure is proportional to the current. The PCM measures the current flowing through the A/T clutch pressure control solenoid valve and uses feedback control to compensate the difference between the actual current and the commanded one. If the measured current for the PCM output duty cycle is not within a specified range (open or short to ground), a malfunction is detected and the P1768 code is set.

6. How do I fix the P1768 code on my 1998 Honda Civic?

Repairs may involve replacing the clutch pressure control solenoid, repairing damaged wiring, cleaning corroded connectors, or, in rare cases, replacing the TCM.

7. How much does it cost to fix the P1768 code on a 1998 Honda Civic?

The cost can range from $150 to $400 depending on whether the issue is with the solenoid, wiring, or the TCM. Labor costs may vary by location.

8. Can low transmission fluid cause the P1768 code on a 1998 Honda Civic?

Low or contaminated transmission fluid might contribute to the issue by affecting hydraulic pressure, so checking and replenishing fluid is recommended.

9. How do I prevent the P1768 code from recurring on my 1998 Honda Civic?

Regular maintenance, including checking transmission fluid levels and condition, and inspecting electrical connections, can help prevent this issue.

10. Does the P1768 code mean the transmission needs to be replaced on a 1998 Honda Civic?
