- How the car detects it
- P2869 states that fork E does not follow its commands: a gear on that fork cannot be engaged or released, although the position input itself may be working. No manufacturer publishes a strategy for P2869; the basis is the CARB 13 CCR 1968.2 requirement to check transmission components for function. The only public method for a fifth rod comes from GM's 2023 Corvette table. There an intrusive integrity routine pushes rod 5 both ways via synchronizer valve 5 and expects more than 100 µm of movement; if nothing moves, GM decides between sensor and valve with a current profile test of the valve and records the sensor fault under P2864, while valve 5 circuit faults use P27D5 to P27D8. Typical causes are a seized rod, a broken fork or a jammed synchronizer.
