P0211: A fault in the control circuit for the fuel injector on cylinder 11
Injector circuit malfunction, cylinder 11
Severity: Severity not verified — if the car runs badly, have it inspected
No source we read says how urgent this code is, so we have not set a severity; have it read and checked rather than assuming it is harmless.
P0211 in short
P0211 means the engine computer found a problem in the circuit for the fuel injector on cylinder 11. TroubleCodes.net lists a failed injector, a fault in the injector circuit, or a problem in the computer's injector driver. It can come with a misfire and, in some cases, a no-start.
Only engines with eleven or more cylinders use this code. It comes from the generic list of injector circuit codes, one for each cylinder.
TroubleCodes.net says the computer sets it when the injector circuit does not behave as expected. The page names three causes: a failed injector, a fault in the wiring, or a fault in the computer's injector driver.
The Delaware DMV list titles P0211 as an injector circuit malfunction for cylinder 11, consistent with the other source.
Most likely causes
These are general causes for this code across vehicles. None is specific to one make or model.
Cause 1: Failed fuel injector on cylinder 11
Common general cause- Why it ranks here
- TroubleCodes.net lists a failed injector first.
- What would change this
- Injector resistance outside spec, or a bad balance test, raises it.
Cause 2: Fault in the injector wiring or connector
Common general cause- Why it ranks here
- The page lists a fault in the injector circuit.
- What would change this
- A missing power feed or ground, or a damaged wire, confirms it.
Cause 3: Fault in the computer's injector driver
Possible — needs testing- Why it ranks here
- The page lists the computer's injector driver as the third cause.
- What would change this
- Rises only when the injector and wiring both test good.
What to test first
Start at step 1. Each result tells you what it means and where to go next.
Step 1: Read all stored codes and look for misfire codes alongside P0211.
IfMisfire codes for the same cylinder are stored
It meansThe injector circuit is the likely cause.
IfNo misfire codes
It meansInspect the injector and its connector.
Step 2: Inspect the injector and its connector, then check injector resistance against the manufacturer's spec and whether the injector driver signal is present (noid light flashes while cranking).
Warning:Fuel injectors sit on a pressurised fuel rail; do not disconnect fuel lines. Leave that to a shop.
IfResistance is out of spec
It meansReplace the injector.
IfNo driver signal, power or ground at the connector
It meansTrace the wiring and then the computer.
Symptoms
- Check engine light
- Engine misfire
- Engine stalls
- Engine cranks but does not start
