What the P1768 code means

P1768 is a manufacturer-specific code: the 1 in the second position means each automaker defines what it means, not the generic SAE standard. The most widespread definition is the one used by Honda and Acura. If your vehicle is another brand, confirm the code text with a scan tool that supports that manufacturer.

Honda and AcuraClutch pressure control solenoid A

In Honda automatic transmissions, the computer controls shifts with solenoids that regulate clutch pressure and torque converter lockup.

The computer sets the P1768 code when it detects a fault in linear solenoid A, which regulates clutch pressure.

Before you start repairs, confirm the make, model, year and engine. With manufacturer codes, the same number can change even between engines from the same brand.

P1768 code symptoms

  • D4 light or check engine light blinking.
  • Harsh shifts or slipping.
  • The transmission goes into limp mode.

Likely causes of the P1768 code

  1. Linear solenoid A worn or dirty.
  2. Dirty transmission fluid. Check the level, condition and viscosity.
  3. Connector. Check the lock tab, the pins and any sign of moisture or corrosion.

How to diagnose the P1768 code step by step

  1. Check the transmission fluid.
  2. Measure the solenoid. It is 3 to 7 ohms.
  3. Inspect the connector for oil and corrosion.

How to fix the P1768 code

  • Replace the solenoid assembly.
  • Change the fluid with the original fluid.

Technical reference data

  • Always use the original Honda transmission fluid.
  • P1xxx codes are manufacturer-specific: confirm the definition with a scan tool that supports your brand.
  • Reference values: check the manufacturer data for your vehicle.

Brand-specific notes

Slipping with this code is a warning sign. Driving on a slipping transmission wears the clutches fast and turns a modest repair into a rebuild.

P1768 on Honda

Very common on the Civic, Accord, CR-V, Fit and Odyssey.

If your vehicle is another brand, check the table above for the meaning its manufacturer gives this code and confirm it with a compatible scan tool.

Frequently asked questions about P1768

What does the P1768 code mean on a Honda?
It means there is a fault in clutch pressure control solenoid A. You may notice harsh shifts or slipping.
Does P1768 mean the same thing on every brand?
No. It is a manufacturer-specific code, so on other brands it may not exist or may mean something different. Confirm it with a scan tool that supports your make.
Can I drive with a P1768 code?
With caution. The transmission can slip with a P1768 code, so avoid long drives and heavy loads until it is checked.
How much does it cost to fix P1768?
Roughly $150 to $700 on a Honda. A fluid change is at the low end, and a solenoid assembly with labor costs more.
Will a P1768 code clear itself?
Not while the solenoid is worn or dirty. After a repair, clear the code and drive to confirm shifts are smooth and the code stays off.
What is the most common cause of P1768?
A worn or dirty linear solenoid A. Dirty transmission fluid and the connector are the next things to check.
