Code Definition

The P1768 code definition varies depending on the vehicle make.

For Acura, Honda, and Isuzu, it refers to the A/T Clutch Pressure Control Solenoid Valve Circuit.

In Acura, Honda, and Isuzu vehicles, code P1768 relates to the A/T Clutch Pressure Control Solenoid Valve Circuit malfunction.

In Ford, it indicates a Performance / Normal / Winter Mode Input Malfunction.

Meanwhile, in Mitsubishi, it’s related to the Transaxle Control Relays Always Off.

Generally, the code is associated with the malfunction of the clutch control solenoid valve, which is responsible for shift control and lock-up control.

The Powertrain Control Module (PCM) measures the current flowing through the valve and detects a malfunction if it’s not within a specified range.

Possible Causes

When your vehicle throws a P1768 code, it’s time to investigate the possible causes.

You’ll need to check for faulty clutch pressure control solenoid valves, which can malfunction due to electrical issues. Inspect the related wiring harness and connectors for signs of damage, corrosion, or wear.

Wiring issues, such as open or shorted circuits, can also trigger this code. Additionally, poor electrical connections or corrosion in the solenoid valve circuit can cause problems.

Symptoms

You’ve probably noticed some unusual behavior in your vehicle’s transmission if the P1768 code has been triggered.

As the clutch pressure control solenoid valve malfunctions, you may experience clutch failure signs like slipping or hesitation when shifting gears.

Transmission problems may manifest as erratic or incomplete shifts, causing your vehicle to jerk or stumble.

You might also notice a decrease in fuel efficiency or a sudden loss of power.

These symptoms can lead to more severe damage if left unchecked, so it’s essential to address the underlying issue promptly.

How to Fix

To fix the P1768 code, start by reviewing the possible causes listed above, which may include a faulty clutch pressure control solenoid valve, an open or shorted harness, or a poor electrical connection in the circuit.

Begin by reviewing possible causes, including faulty solenoid valve, open/shorted harness, or poor electrical connection.

Next, visually inspect the related wiring harness and connectors for damage, looking for broken, bent, pushed out, or corroded connector pins.

Repair or replace damaged components as needed.
