P0200 on Nissan
Injector Circuit/Open
P0200 on Nissan vehicles indicates injector circuit/open. Au7o has documented this code across 1 Nissan model — most commonly on 300ZX. Generic injector circuit fault. The PCM commands the fuel injectors on and off via internal driver transistors and monitors each circuit for proper voltage and current. P0200 sets when the PCM detects an open or out-of-range condition affecting the overall injector circuit (rather than one specific cylinder) — often pointing to a shared component such as the injector power feed, main relay, or fuse. Typical repair costs on Nissan range from $100 to $800, depending on the specific model and root cause.
Common Causes of P0200
- •Open or shorted injector wiring harness between PCM and injectors
- •Blown injector fuse or failed injector/main relay (shared power feed)
- •Corroded, loose, or backed-out injector connector
- •Faulty fuel injector (internal open winding)
- •Failed PCM injector driver
P0200 on Nissan by Model
Nissan 300ZX(1 issue)
- Fuel injector sub-harness / connector melting and corrosion (EV1 plugs)1990-1996
The Z32's six factory fuel-injector connectors (early EV1-style plugs) and the injector sub-harness sit directly atop a hot intake and are subjected to decades of underhood heat cycling. The connector plastic becomes brittle, the terminals corrode/oxidize, and the wiring insulation hardens and cracks — sometimes literally melting/discoloring at the plug. On twin-turbo cars the harness runs even hotter. The result is intermittent or dropped injector signal, most often on cylinders that live closest to the turbos/heat. This is one of the single most common driveability complaints on aging Z32s and is considered a maintenance item, not an if.
