P0211: Injector Circuit/Open - Cylinder 11

SAE J2012 APR2002: injector circuit/open, cylinder 11. P0291 is the low row and P0292 is the high row. The printed pair is RepairPal's one-injector average, which does not list an eleventh injector.

What does P0211 mean?

SAE J2012 APR2002 names P0211 Injector Circuit/Open - Cylinder 11. The directional rows are P0291, cylinder 11 injector circuit low, and P0292, cylinder 11 injector circuit high. Section 3.1's Circuit/Open text is a fixed value or no response, and it is also the general code used when low and high can be detected separately.

Cylinder 11 is an SAE assignment, not a count of the injectors on the engine in front of you. The 2009 Cobalt procedure, the 2008 Envoy procedure, Volkswagen tips 01-20-02 and 97-18-02, and GM 07_GRP01_All Engines do not define P0211. GRP01's injector-control list ends at cylinder 8. There is no 3 ms or 6 ms threshold in those documents for cylinder 11.

A twelve-cylinder or other engine that actually has an eleventh injector is tested from its own schematic. The three results that must not be collapsed are an open, a short to ground, and a short to voltage. Continuity is both ends disconnected, ignition off. Short to ground is the wire to ground with the module disconnected. Short to voltage is key on, injector unplugged, module disconnected, and a voltage that is not the open-circuit bias this chart prints. Seeing that bias with the injector unplugged is the expected disconnected result, not a failed short test.

RepairPal's national injector page, updated 3 September 2026, prices one injector replacement and does not publish an eleventh-injector line. Depressurize before a fitting is opened. High-pressure fuel can penetrate skin. Do not feed 12 volts to the injector to listen for a click.

Common causes

  • An open cylinder 11 control wire, continuity failed with both ends off and the ignition off
  • A short to ground that is still there with the module disconnected
  • A short to voltage that is still there with the module disconnected and does not match the chart's bias
  • A coil that misses the resistance this vehicle's chart prints
  • A test procedure borrowed from a four-, six-, or eight-injector chart that never mentions cylinder 11
  • An injector purchased for an engine that has no eleventh injector
  • A driver in the module, after the wire is cleared

Symptoms

  • P0211 stored
  • P0291 or P0292 stored when the fault is the low or high row instead
  • No millisecond limit available from GRP01, because that sheet has no P0211 row
  • An eleventh injector only where the diagram draws one
  • A repair aimed at a cylinder the engine does not have

Diagnostic steps

  1. 1.Match the stored code to the diagram's injector count. Eleven is not assumed.
  2. 2.If P0291 or P0292 is the code that is actually present, follow that row. P0211 is the Circuit/Open row.
  3. 3.Do not use Cobalt terminals, the Envoy lamp branches, or a Volkswagen T8 part number. Those documents stop earlier.
  4. 4.Ignition off, unplug the injector the diagram labels 11, and measure the winding against the published spec.
  5. 5.Disconnect the module. Check continuity, short to ground, and then, key on, short to voltage against the disconnected-circuit voltage in this chart.
  6. 6.Depressurize with the published procedure. Do not open a high-pressure joint to bleed it by cracking a fitting.
  7. 7.Replacement, when the injector is the failed part, is priced below as RepairPal's one-injector average. That page's intake-removal description applies to the engines it describes. It says the job is not DIY.
  8. 8.Clear the code only after the monitor that set it has been run again.

Repair cost

$770 – $950 (one fuel injector replacement, parts and labor, RepairPal national average updated 3 September 2026; no eleventh-injector line is on that page, and wiring is outside this pair)

RepairPal's fuel injector replacement, updated 3 September 2026, averages $768–$953, rounded to $770–$950. Labor is $304–$446 and parts are $464–$507. The 2026 Hyundai Tucson line is $456–$604 and is outside the pair. An eleventh injector can be priced differently in this engine's parts book. Wiring is not in the pair. Check-engine diagnosis is $125–$183 and is separate.

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.

Frequently asked questions

How much does P0211 cost to fix?

One fuel injector replacement is $770 – $950 (one fuel injector replacement, parts and labor, RepairPal national average updated 3 September 2026; no eleventh-injector line is on that page, and wiring is outside this pair). That is RepairPal's 3 September 2026 national average of $768–$953, parts and labor. The page does not list an eleventh injector. The 2026 Hyundai Tucson line is $456–$604 and is outside the pair. Wiring is not in the pair. Diagnosis is $125–$183 and is separate.

What is the difference between P0211, P0291, and P0292?

P0211 is Injector Circuit/Open - Cylinder 11. P0291 is cylinder 11 injector circuit low. P0292 is cylinder 11 injector circuit high. SAE measures low and high with the circuit connected. An unplugged connector is a different test, used to see whether the harness or the injector is holding the pin there.

Is there a published resistance for cylinder 11?

Not in J2012, and not in the Cobalt, Envoy, or GRP01 pages cited for the lower cylinder codes. Use the spec printed for this engine. A number brought over from another injector is not that spec.

Can I drive with P0211?

Only far enough to confirm the engine has an eleventh injector and to test its circuit, without hard acceleration. Depressurize before the injector is removed.

About This Diagnostic Information

AutoLogicTools diagnostic guides explain OBD-II trouble codes using recognized code definitions, standard automotive diagnostic principles, and practical automotive context. A trouble code records a condition detected by a control module. It does not automatically identify a failed part, and the right diagnostic procedure can vary by vehicle.

Manufacturer service information, technical service bulletins, wiring diagrams, and vehicle-specific procedures should take precedence when available.
