OBD-II trouble code
P0200: Injector Circuit/Open
SAE J2012 APR2002: injector circuit/open. The row does not name a cylinder. P0201 through P0212 do. RepairPal's injector replacement, updated 3 September 2026, averages $768–$953 and describes intake-manifold removal as part of the job.

What does P0200 mean?
SAE J2012 APR2002 names P0200 Injector Circuit/Open. P0201 through P0208, and further cylinder numbers where the table lists them, add the cylinder. P0200 does not. The word Open is in the 2002 row. The chart for this calibration says whether the stored result is an open, a short, or a driver fault the monitor lumps into this code.
How the injector is powered is the diagram's. Many port injectors are fed battery voltage on one side and grounded by the module for the pulse. Many direct-injection injectors are driven by a boosted voltage, and a 12-volt resistance check does not describe that driver. Measure resistance, if the chart asks for it, with the injector unplugged and the ignition off, and compare it with the published spec. Do not apply 12 volts by hand to see if it clicks.
RepairPal's fuel injector page, updated 3 September 2026, starts with a visual inspection, then a scan, and it expects a misfire on one cylinder when an injector is the cause. It says the injector may have to come out for a bench test. Replacement, on that page, removes the intake manifold, can include a coolant or oil drain, and includes a new manifold gasket. Some plastic manifolds have no oil or coolant passages and the job is smaller. The battery is disconnected and fire precautions are taken. RepairPal says the repair is not DIY.
A wiring or connector fault sets an injector-circuit code with a good injector. RepairPal's average is the injector job, not a connector. A misfire code can be stored with P0200. Its absence does not clear the injector circuit. Misfire detection is suspended in conditions this calibration lists.
Depressurize with the published procedure before a rail or an injector is opened. High-pressure direct-injection fuel can penetrate skin.
Common causes
- A connector or a wire in the injector circuit, which is not priced by the injector average
- An injector winding that fails the published resistance check, unplugged, ignition off
- The wrong cylinder's injector replaced because P0200 does not name one
- A 12-volt click test on a direct-injection injector that uses a boosted driver
- An intake gasket reused after the manifold came off, against RepairPal's replacement description
- A module driver, only after the wiring and the injector test to the chart
Symptoms
- P0200 stored
- A misfire code, when the monitor is enabled and a cylinder is not getting the commanded pulse
- A rough idle or a dead cylinder you can find with a balance test
- No cylinder number in the code, so every injector circuit is still in play
- A fuel smell or a leak only if the rail was opened and not depressurized correctly
- The engine still runs on the cylinders whose circuits are intact
Diagnostic steps
- 1.Read every injector code. If a P0201-and-up code names a cylinder, start there. P0200 alone does not.
- 2.Inspect the connectors you can see without removing the intake. Do not remove the manifold to perform the inspection that was supposed to decide whether the manifold comes off.
- 3.Ignition off, unplug the injector the diagram assigns, and measure winding resistance against the published spec. Do not power the injector from the battery.
- 4.Identify the driver. A port injector's battery feed and ground pulse are not the test for a boosted direct-injection driver.
- 5.Check continuity from the module pins to that injector with both ends disconnected and the ignition off.
- 6.When the injector is the failed part, RepairPal's job removes the intake, disconnects the battery, uses fire precautions, and fits a new gasket. Depressurize first. Some manifolds also require a coolant or oil drain. That page says this is not a DIY repair.
- 7.Verify with a cylinder-balance or a logged misfire count, not only a cleared code. A missing misfire code does not prove the circuit.
Repair cost
$770 – $1,060 (one fuel injector replacement, parts and labor, from RepairPal's national average through the Ford F-150 year line; wiring and a module driver are outside this pair)
RepairPal's fuel injector replacement, updated 3 September 2026, averages $768–$953 (labor $304–$446, parts $464–$507). The Ford F-150 year line on that page is $814–$1,061. The printed pair rounds those to $770–$1,060. RepairPal's replacement description removes the intake manifold, and some of those jobs drain coolant or oil and include a manifold gasket. A connector repair is not in the pair. Check-engine diagnosis is $125–$183 and is separate. RepairPal states the replacement is not a DIY job.

DIY vs shop
Leave this one to a qualified shop. The barrier here is high-pressure fuel components, where residual pressure remains after shutdown and escaping fuel can penetrate skin. DIY attempts often produce a more expensive problem than the original code.
