- How the car detects it
- P22E1 marks an open control circuit at the cylinder 3 gas injector. Circuit continuity checks of this kind run all the time: California's OBD rule defines continuous monitoring as always enabled with at least two samples per second, so a break is caught within moments once the gas system is in use. No maker documents P22E1 openly. TransEco's AFCM list and Ford's 2014 code list give cylinder 3 only the Low/High codes P22E2 and P22E3, and TransEco counts an open line as Low. On GM's bi-fuel pickups the gas injectors sit on separate rails with hoses leading to nozzles at each intake runner, and their wiring runs along those rails; a pulled connector after work in that area is a common reason. Bi-fuel cars carry on with gasoline.
