P0705 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.
Scan your own car in about 60 seconds: see whether P0705 is really what it has, how urgent it is, and what the fix should cost. Free on iPhone and Android, on any ELM327 adapter.

P0705 is a transmission-related diagnostic trouble code classified as high severity. When your vehicle's ECU detects this condition, it stores P0705 and illuminates the check engine light.
If your vehicle has triggered P0705, you may notice one or more of these symptoms:
Here are the most common causes of P0705:
No - address this immediately. You can usually limp home, but the transmission often drops into fail-safe (stuck in 3rd or 4th), reverse lights may not work, and the starter interlock can misbehave. Don't take it on the motorway before it's fixed.
Follow these steps to pinpoint the root cause of P0705:
Repair costs for P0705 vary depending on the root cause and your vehicle. Here are typical estimates:
Prices estimated as of March 2026. Costs vary by region, vehicle, and shop.
P0705 behaves differently depending on your vehicle. Select your car below for model-specific causes, known issues, and adjusted cost estimates:
The digital TR sensor on 4R70W, 4R75W and 5R55 transmissions is a documented weak point. Intermittent P0705 from internal sensor wear is common on 5.4L Triton trucks.
U140E and U240E transaxles use an external park/neutral position switch bolted to the manual valve shaft. Adjustment requires aligning the switch groove with the neutral basic line, torque 5.4 Nm.
09G Aisin autos (Mk5/Mk6 2.5L, 1.4 TSI) commonly fail the multifunction switch F125 on top of the valve body. DSG (02E/DQ250) integrates the sensor into the mechatronic and P0705 usually points to mechatronic wear.
E90/E91 with ZF 6HP19/6HP21: the range sensor lives inside the mechatronic unit. The well-known mechatronic sleeve (adapter) leak dumps ATF into the connector and takes the sensor with it.
8th and 9th gen Civics with the 5-speed auto: the transmission range switch sits on top of the transaxle. Honda service data requires aligning the switch's neutral index mark with the shaft mark within +/-1 mm.
These codes are often seen alongside P0705 or indicate related issues:
Short local drives are usually fine if the trans still engages, but it's often stuck in fail-safe (one gear, no downshifts) and reverse lights may be dead. For anything over a few kilometres or highway speeds, get it fixed or towed.
The range sensor doubles as the neutral safety switch. If it's misaligned or worn, the PCM sees Park as invalid but still reads Neutral correctly, so cranking only works in N. It's the classic symptom of a bad or misadjusted TR sensor.
Often yes. Loosen the sensor bolts with the shifter in Neutral, align the mark on the sensor with the shaft flat, and retighten. On Fords and Toyotas this fixes maybe half the P0705s I've seen, no parts needed.
Related but not identical. P0705 is a digital/PRNDL circuit fault (implausible combination), P0706 is a range/performance issue on the same sensor. Diagnosis overlaps but P0706 usually means the signal is in-range but wrong for the selected gear.
Yes. Low cranking voltage or a corroded PCM ground can set transmission codes including P0705. Check battery voltage and clean the engine-to-body ground straps before condemning the sensor.
A 15 euro Bluetooth adapter and a free phone app read the exact fault code a shop charges 30 to 100 euros to pull. Here is how to do it yourself in 5 minutes.
Engine revs rise but the car does not. Check the fluid first: a slipping automatic can be a $150 service or a $4,000 rebuild, and the tells differ.
Transmission repair costs $150 for a fluid service, $2,000 to $4,000 for a rebuild, or $3,000 to $5,500 for a reman unit. And when the car is not worth it.
A flashing check engine light means the engine is misfiring right now. Pull over and read the code: the fix is usually $80 to $400, the delay costs $1,500 up.
An unfamiliar symbol just lit up and you need to know whether to stop. Read the colour first, then find your symbol in the table: every one carries its verdict.
Your car logged P0705. Skanyx reads it on any standard Bluetooth OBD2 adapter, tells you whether it is safe to keep driving, and shows the €40-€1500 repair range so you know the number before a shop quotes you. Free on iPhone and Android, and you do not need to be a mechanic to read it.
