P0205 code definition
Injector Circuit Malfunction - Cylinder 5
What the P0205 code means
P0205 is a generic diagnostic trouble code which indicates that the injector circuit for cylinder 5 has out of range voltage or resistance. This is detected by the Engine Control Module (ECM) as it tries to control the circuit.
P0205 can be seen with misfire, and lean/rich condition codes.
P0205 is similar to P0200 - P0202, P0204, and P0206-P0212.
What causes the P0205 code?
Shorted or open wiring harness
Fuel injector cylinder 5 is faulty
ECM has failed
Faulty electrical connection
What are the symptoms of the P0205 code?
Check Engine Light is triggered by the ECM and observed on the dashboard
Failsafe mode (precaution to prevent damage to the vehicle) is enacted by the ECM
Failsafe mode remains in effect until normal operation is detected or the fault is fixed
Gas mileage is poor
Fuel system has lean or rich condition
Engine has a lack of power
Engine runs roughly, poorly, or dies while running
Vehicle is hard to start or does not restart once it has died
How does a mechanic diagnose the P0205 code?
Hooks up a scan tool into the OBD-II port to find any codes that may be stored in the ECM
Observes freeze frame data associated with each code (codes will either be Pending or Active)
Clears codes and performs a test drive using information obtained from the freeze frame data to duplicate the conditions that were present when the code was set
If the P0205 code returns, performs a visual inspection of the injector circuit
Uses scan tool to monitor voltage and resistance found at cylinder 5 fuel injector; checks for proper voltage at the fuel injector itself
Uses a noid light to monitor the on/off pulse of the fuel injector
Performs a test of the ECM
Common mistakes when diagnosing the P0205 code
Mistakes can easily be made by anyone if they skip steps or do not complete all steps required. These steps should always be followed to avoid unnecessary repairs, and save time and money.
How serious is the P0205 code?
P0205 can have some symptoms that are cause for concern such as the engine dying while driving. A vehicle with these issues should not be driven and should be diagnosed as soon as possible for safe driving.

Engine is misfiring, check engine code said cylinder 5, prob ignition coil and would like to change the coil but I cannot locate the cylinder numbers do you have a diagram so I can locate the correct coil?
