OBD2 Error Code P0705: How to Fix It

Q: Can I drive with P0705 error code?

You can drive short distances to get to a repair facility, but avoid extended driving. The transmission may not shift properly, get stuck in one gear, or the engine may not start in some cases. This can cause further transmission damage if ignored.

Q: How much does it cost to fix P0705?

If it's just a faulty transmission range sensor, expect to pay $150-$400 for parts and labor. However, if internal transmission damage is present, costs can range from $1,500-$4,000 for transmission rebuild or replacement.

Q: What causes transmission range sensor failure?

Common causes include normal wear after 100,000+ miles, electrical problems like corroded connections or damaged wiring, low transmission fluid, internal transmission mechanical problems, or exposure to excessive heat or moisture.

Q: How do I know if my transmission range sensor is bad?

Symptoms include engine not starting in Park, transmission stuck in one gear, incorrect gear display on dashboard, harsh or delayed shifting, and of course, the P0705 error code appearing on diagnostic scans.

Q: Can a bad battery cause P0705 code?

Yes, a weak or failing battery can cause erratic electrical behavior including false P0705 codes. Always check battery voltage and charging system before replacing transmission components. Battery voltage should be 12.4V or higher when engine is off.

Abstract

Error code P0705 indicates a malfunction in your vehicle's transmission range sensor circuit, also known as the PRNDL (Park, Reverse, Neutral, Drive, Low) input. This sensor tells the engine control module which gear position you've selected, and when it fails, you may experience shifting problems, inability to start the engine, or the transmission getting stuck in one gear.
