Technical Description of OBD-II Trouble Code
Malfunction in the Circuit of Cylinder 5 Injector
What does that signify?
This diagnostic trouble code (DTC) is a generic powertrain code, which means that it applies to OBD-II equipped vehicles. Although generic, the specific repair steps may vary depending on make/model.
P0205 indicates that the PCM detected a fault in the injector or the wiring to the injector. It monitors the injector and when the injector is activated, the PCM expects to see the voltage pulled “low” or close to zero.
When the injector is switched off, the PCM expects to see a voltage that is close to battery voltage or “high”. If it doesn’t see the expected voltage, the PCM will set this code. The PCM also monitors resistance in the circuit. If the resistance is excessively low or high, it will set this code.
Potential Symptoms
The symptoms for this code will likely include a misfire and a rough running engine. Poor acceleration. The MIL will also be illuminated.
Causes
The causes of a P0205 engine light code could be any of the following:
