mattboyer | 05-03-2006 05:23 AM | FAILED EMISSIONS TEST W/ P1423 CODE MY WIFES 97 318ti has had the hidden p1423 code show up during an annual emmissions test yesterday....NO warning ( check engine light on) ...so suprise for me I've been studying the secondary air system and all that's involved all day now....here's where I'm at........I pulled the air pump off tonight ..hooked it up to 12 vlts and suprise to me it worked ....and yes it does sound like a hair dryer .....now I've owned the car for 1.5 years and I have never heard that air pump run .....so I have the plug from the air pump unplugged and my volt meter plugged in to the end , turn on the ignition and I have nothing , no power to the air pump......where do I go next , I can't locate which fuse or a relay would turn this thing on...(JUST ADDED 1.5 HOURS LATER) I guess the car finally cooled down enough..I hooked my volt meter to the plug that goes to the air pump and started the car and it read 14.08 volts so I turned the car off and thought about plugging it back into the air pump....but thought I better double check to make sure I have voltage before I hook it up.....well I hit the ignition again and I had no voltage at the plug...I'm going to try and let the car cool down again.... |
