What the P1705 code means

P1705 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.

ManufacturerMeaning of P1705
Honda and AcuraAutomatic transmission position switch short circuit (multiple positions at once)

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

The computer sets the P1705 code when the position switch signals two or more positions at once.

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.

P1705 code symptoms

  • Check engine light on, or the D4 light blinking.
  • Erratic shifting.
  • Reverse lights that do not work.

Likely causes of the P1705 code

  1. Position switch out of adjustment or failed. Confirm it with the tests in the diagnosis section.
  2. Connector with moisture. Check the lock tab, the pins and any sign of moisture or corrosion.
  3. Wiring. Look for rubbing against the engine, the chassis or the exhaust.

How to diagnose the P1705 code step by step

  1. Read the positions on the scan tool while you move the shift lever.
  2. Adjust the switch and check that each position reads alone.
  3. Inspect the connector for moisture and corrosion.

How to fix the P1705 code

  • Adjust or replace the switch.
  • Repair the connector.

Technical reference data

  • The switch is on the side of the transmission, next to the shift cable.
  • 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

The scan tool will show you at once whether the switch reports one position or several, which makes this an easy code to confirm.
