P0205 Check Fuel Injector Harness Resistance
injector #5
1. Turn ignition switch to OFF position.
Disconnect suspect fuel injector harness connector.
Using a DVOM, measure resistance of fuel injector circuit signal and VPWR circuit between PCM harness connector and suspect fuel injector harness connector
If both resistance measurements are less than 5 ohms, go to next step. If either resistance measurement is 5 ohms or more, repair open in fuel injector signal or VPWR circuit.

2. Turn ignition switch to OFF position. Disconnect PCM harness connector(s). Ensure suspect fuel injector is disconnected. Using a DVOM, measure resistance between SIG circuit, and PWR GND and VPWR circuits at PCM harness connector
each resistance measurement is more than 10 k/ohms, go to next step. If either resistance measurement is 10 k/ohms or less, repair short between circuits
3. Turn ignition switch to OFF position. Reconnect PCM and fuel injector connector(s). Use Rotunda fuel injector tester from Fuel Tester Kit (113-00114) to flow test fuel injectors. Follow injector tester instructions. If fuel injector flow or leakage rate is not okay, replace defective fuel injector(s).
