Open or short wiring harness for the cylinder 2 injector circuitĪs with most error codes, qualified mechanics check this error code by hooking it up to advanced scanner and check for the codes.Poor or broken electrical connections in the connector or harness.Corroded fuel injector, connections or wiring.The most common causes for this code include: The problem must be fixed before the vehicle switches back to normal operation from failsafe mode.Įrror Code P0206 is quite unique, as symptoms can be felt even before the Check Engine light is activated in the dashboard, as the vehicle may display a rich or lean condition alongside with engine misfire. Once the code is set, the vehicle will activate its failsafe mode, keeping the engine safe from further damage. The PCM also works by monitoring the resistance circuit, and sets the code if it’s too high or too low. If it doesn’t see what it expects to see, it detects a low or high voltage drop or resistance at injector 6, which activates the Error Code P0206.

When the injector is switched off, the PCM expects to see a voltage close to battery voltage or “high”. The PCM works by monitoring the injector, and when the latter is activated, it determines whether the voltage pulled “low” or close to zero. Additionally, this code can be seen in engine misfire, rich and lean conditions. Specifications in definition, troubleshooting and repairs vary from one make and/or model to another. This code is a generic trouble code, meaning it applies to all vehicles equipped with OBD-II, or vehicles made in 1996 to present. This code means the PCM (powertrain control module, also known as ECM or engine control module in other makes) has found a problem with the injector or its wiring, or in injector circuit for cylinder 6. Error Code P0206 is defined as Cylinder 4 Injector Circuit Malfunction.
