P2806
Transmission Range Sensor Alignment
Transmission
Generic OBD-II
Medium
What it means
P2806 means the transmission range (PRNDL) sensor's alignment is out of tolerance, so the module can't reliably tell which gear the shifter is in. Because this sensor also feeds the neutral-safety and gear-selection logic, a misalignment can cause a no-crank in Park, wrong-gear engagement, or harsh shifts. It's usually a sensor adjustment, linkage, or wiring issue.
Medium
Can I keep driving? Possible no-start or odd shifts — a misaligned range sensor can stop the engine cranking except in Park/Neutral and cause the wrong gear to engage; get it corrected soon.
Common symptoms
What you'll notice
- Engine won't crank in Park (may start only in Neutral, or vice versa)
- Harsh, delayed, or wrong-gear engagement
- Gear position on the dash doesn't match the shifter
- Reverse lights not working
- Check-engine light on
Common causes
Most likely first
- Misadjusted or misaligned transmission range (PRNDL / neutral-safety) sensorLikely
- Worn or faulty range sensorCommon
- Open, short, or high resistance in the range sensor circuitCommon
- Poor connector contact at the sensorLess often
- Shifter linkage out of adjustmentLess often
How to diagnose & fix
Work through it in order
- Scan and read freeze-frame data to confirm the range sensor is the source.
- Check the shifter linkage and range sensor alignment/adjustment to spec.
- Inspect the sensor wiring and connector for damage or corrosion.
- Watch the range sensor reading live while moving through each gear.
- Realign or replace the sensor, then verify start-in-Park/Neutral and re-test.
FAQ
Quick answers
Is it safe to drive with P2806?+
Use caution. A misaligned range sensor can prevent starting except in certain positions and can engage the wrong gear, which is unsafe — have it corrected before relying on the vehicle.
Can I just clear P2806?+
It returns as soon as the sensor reads out of alignment again. The sensor or linkage must be adjusted or replaced to fix it properly.
