Honda CR-V Sixth Generation (2023-present) check engine light on with code P0700 what does it mean

Solution

1. Preparation

• Gather tools and materials required for the repair.
• Ensure the vehicle is parked on a level surface and the engine is off.
• Disconnect the battery to prevent electrical shorts.

2. Check Transmission Fluid

• Remove the transmission dipstick and wipe it clean.
• Reinsert the dipstick and then remove it again to check the fluid level.
• If low, add the correct type of transmission fluid (e.g., Honda ATF DW-1) until it reaches the full mark.
• If the fluid is dark or has a burnt smell, a transmission fluid change may be necessary.

3. Inspect Wiring and Connectors

• Visually inspect the wiring harness connected to the TCM for any frayed or damaged wires.
• Check all connectors for corrosion or loose connections.
• Clean connectors with electrical contact cleaner and ensure they are securely fastened.

4. Test Transmission Control Module (TCM)

• Reconnect the battery.
• Using the OBD-II scanner, check for any new trouble codes after clearing existing codes.
• If the P0700 code persists, perform a continuity test on the TCM wiring using a multimeter.
• Replace the TCM if it fails any tests or does not communicate properly.

5. Verify Vehicle Speed Sensor (VSS)

• Locate the VSS and inspect its wiring and connector.
• Test the VSS with a multimeter to ensure it is sending the correct signals.
• Replace the VSS if it is faulty.
