P0705 on Honda: Causes, Symptoms and Fix Cost

Quick Answer
High SeverityNot safe to driveHonda

P0705 on a Honda means the PCM is seeing an invalid or impossible gear-position signal from the transmission range sensor. The computer no longer knows which gear you've selected, so it defaults to safe shift maps and often disables the starter in some positions.

Typical repair cost, all makes€40 - €1500

Connect any standard Bluetooth OBD2 adapter to your Honda and Skanyx tells you what P0705 means on that engine, whether it is safe to keep driving, and what the fix should cost. Free on iPhone and Android.

What does P0705 mean on a Honda?

The Quick Answer above is the generic definition. What follows is the model-specific detail for the Honda models that log P0705.

Honda Civic

2006-2015

8th and 9th gen Civics with the 5-speed auto: the transmission range switch sits on top of the transaxle. It has to be aligned closely with the shaft mark, so work to the alignment marks rather than by eye when refitting it.

What causes P0705 on a Honda?

Beyond the generic causes listed on the main P0705 page, these are the patterns noted for Honda models:

Honda CivicRange switch alignment marks out of spec after shift cable replacement
Honda CivicConnector corrosion from road salt on northern-market cars

How to diagnose P0705 on a Honda with OBD2

Follow these steps to pinpoint the root cause of P0705:

  1. Pull all stored codes plus freeze frame, note any companion codes like P0700, P0715 or P0720
  2. Watch the gear position value while shifting slowly through P-R-N-D-2-1 and confirm each position matches the shifter. Some cars report it as standard OBD2 live data; many need manufacturer-level software
  3. Check shift cable adjustment: the shifter detent must land dead centre in each transmission position, not on the edge
  4. Inspect the range sensor connector for ATF intrusion, green corrosion, or spread pins
  5. Back-probe the sensor: verify 5V reference and clean ground with a multimeter
  6. Measure sensor resistance or voltage in each gear against the factory table (values differ per manufacturer)
  7. Wiggle-test the harness between sensor and PCM while watching the gear position value to catch intermittent breaks
  8. Only if sensor, wiring, and grounds all pass, verify PCM/TCM power and consider module fault
