1.what the difference btw power ground g17 g24 b27 and sensor ground b29 b38 b39?
And can i use one of them to provide ground for coils or injectors??
Thanks

The sensor grounds are used for sensors such as the TPS, IAT and ECT and must be used to ensure an accurate reading. The power ground on the other head is the high current ground for the ECU and must be wired to the engine block. The coil ground should be wired directly to the cylinder head or block and the injectors ground to the injector drives, not an ECU ground. The injectors are provided a permanent 12V and the ground is switched to turn the injector on and off.
Thanks for the replay
