- How the car detects it
- P0200 is the injector circuit fault without a cylinder assignment. The large US manufacturers do not use it – GM and Ford report injector faults per cylinder (P0201 ff) or as faults of the shared injector supply (P062D/P062E, P2146 ff). Saab documents it on the 3.0 V6 diesel of the 9-5, whose injectors are driven by a separate power stage behind the glovebox: there P0200 means an electrical fault in that power stage or its wiring, and the engine is shut down. Generally the cause lies in something all injectors share – supply, fuse, relay, ground or driver stage – so several cylinders are affected at once. CARB does not require separate codes for each kind of circuit fault.
