Hello Members;

I have a Cel occuring.It was cleared once but came back in approximately 1 week. The vehicle does not seem to suffer from any symptms. The codes are;

#1 18010 Power supply terminal 30
P1102-002 Voltage too low intermintant

#2 17544/ P1136-Fuel trim: bank 1

#3 16555/P0171 system lean

I beleive the first code it due to me disconnecting and charging the battery a few times.

Possible causes??-- MAF sensor, Vaccum leak, Fuel pressure regulator, fuel pump


I thought I would clean the MAF sensor

Is there an engine component diagram that shows the vacuum lines. I know the lines to the fuel pressure regulator can crack at the T connection, as well as some braided vac lines which can deteriorate can be the culprits. I am trying to inspect them visually to see if I can find anything, but am new to this vehicle. Something to help me identify them woud be great.

Does anyone have a picture of the Vacuum diagram in the engine bay?
