Technical Description of OBD-II Trouble Code
Malfunction in the Injector Circuit of Cylinder 11
What does that signify?
This diagnostic trouble code (DTC) is a generic powertrain code that is applicable to vehicles equipped with OBD-II. Although it is a generic code, the specific repair steps may vary depending on the make and model of the vehicle.
P0211 indicates that the PCM has detected a fault in either the injector or the wiring connected to the injector. The PCM monitors the injector and expects to observe a voltage that is pulled “low” or close to zero when the injector is activated.
When the injector is switched off, the PCM expects to see a voltage that is close to the battery voltage or “high”. If the expected voltage is not detected, the PCM will set this code. The PCM also monitors the resistance in the circuit and will set this code if the resistance is excessively low or high.
Potential Symptoms
The symptoms associated with this code are likely to include a misfire and a rough running engine, as well as poor acceleration. The MIL (Malfunction Indicator Lamp) will also be illuminated.
Causes
The potential causes of a P0211 engine light code could be any of the following:
