What P2867 means
P2867 reports that the fork E sensor signal is present but unsteady. GM's Corvette TCM times each cycle of the digital rod 5 signal and sets the code, Type A, when the frequency drops below 1500 Hz or rises above 2500 Hz for at least 150 ms, with the same voltage and cranking exclusions as the low and high tests. So the sensor keeps pulsing, just not at a rate the module accepts. Such dropouts are usually caused by a loose pin, a chafed shield picking up interference, or a sensor beginning to fail with heat. The Mercedes 8G-DCT diagnosis list names fork E sensor faults but not this number. Unlike P2865 and P2866, the fault may come and go, so a stored code without symptoms is common at first.
P2867 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 8 hours
- Clears after repairAfter a drive cycle
Symptoms of P2867
- Sporadic warning, sometimes without noticeable effect
- Occasional lockout of fork E gears
Common causes of P2867
- Most likelyLoose or fretted terminal in the fork E sensor circuit
- PossibleDamaged shielding letting electrical noise into the signal
- PossibleSensor electronics failing intermittently when hot
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2867 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 8 | Area: transmission. |
| 67 | The exact fault in that area. |
What to do next
- Note P2867 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2867
What does P2867 mean?
P2867 means "Shift Fork E Position Circuit Intermittent". P2867 reports that the fork E sensor signal is present but unsteady. It is a generic code, so it means the same on every make.
Is it safe to drive with P2867?
Drive gently and only to a workshop. With P2867 the car can go into limp mode (reduced power) to protect itself.
Will P2867 fail an emissions test?
Yes, it can. P2867 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2867 to fix?
Difficulty: hard. A typical repair takes 0.5 to 8 hours of work. This is a job for a workshop.
Will P2867 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
