What Does P0211 Mean?
This code indicates a malfunction in the fuel injector circuit for cylinder 11. The ECM has detected an electrical fault preventing proper fuel injection to cylinder 11. This code applies exclusively to V12 or high-cylinder-count engine configurations. The injector is not being driven correctly.
Common Causes
35%
Defective cylinder 11 fuel injector with failed internal solenoid coil
30%
Wiring or connector fault in the cylinder 11 injector circuit caused by heat, vibration, or rodent damage
20%
ECM internal driver transistor failure for the cylinder 11 output
15%
Injector bank power supply issue from relay or fuse affecting cylinder 11
Diagnostic Steps
1
Step 1: Measure cylinder 11 injector coil resistance with connector removed. Verify reading within manufacturer specification.
2
Step 2: Confirm 12V power at the injector connector with key on.
3
Step 3: Verify ECM pulse signal at the cylinder 11 connector using a noid light during cranking.
4
Step 4: Swap the cylinder 11 injector with an adjacent cylinder if physically possible to isolate the fault.
5
Step 5: Inspect the full length of the cylinder 11 injector wiring for damage, focusing on areas where the harness passes near exhaust components or through tight routing channels.
Estimated Repair Cost
$250 - $950
Parts + labor, varies by vehicle and location
This code indicates a malfunction in the fuel injector circuit for cylinder 11. The ECM has detected an electrical fault preventing proper fuel injection to cylinder 11. This code applies exclusively to V12 or high-cylinder-count engine configurations. The injector is not being driven correctly.
The most common cause of P0211 (Injector Circuit Malfunction - Cylinder 11) is: Defective cylinder 11 fuel injector with failed internal solenoid coil
Typical repair costs for P0211 range from $250 to $950, depending on the vehicle, location, and whether you do it yourself or go to a shop.
A cylinder 11 injector fault causes a misfire and raw fuel in the exhaust. On V12 engines, labor access is significant but the converter damage risk remains.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P0211 to identify the root cause.
