P2867Shift Fork E Position Circuit Intermittent
- Generic OBD-II code · Powertrain
- Turns on the check-engine light
- Matters for the ITP
- Can trigger limp mode
- Needs a drive cycle to confirm a fix
- How the car detects it
- 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.
- What you may notice
- Sporadic warning, sometimes without noticeable effect
- Occasional lockout of fork E gears
- Likely causes
- LikelyLoose or fretted terminal in the fork E sensor circuit
- PossibleDamaged shielding letting electrical noise into the signal
- PossibleSensor electronics failing intermittently when hot
- Inspection (ITP)
- Matters for the ITP. While the check-engine light is on, the car fails the emissions check.
