Thread: 05 gtp noises from fusebox under hood and check engine light stays on when car is off

ok so my fuse box is making like a clicking noise i can hear in the throttle body and the p/train relay #40 and there is like a tapping or pulsing noise coming from the fuel pp relay #41 the noises stop if the relay is removed but check engine light stays on all the time the car is off and key is in my pocket any info would be appreciated thanks in advance

its draining myt battery i can still start and drive ,y car ill get back to u in a lil with the codes that i get

fuse box getting hot? it smell burnt? if so you need to take the box off the fender and open it to see the back side where all the wires go in. cars have caught fire from a bad fuse box. so unhook the battery when parked to be safe if you smell or feel heat from it.

i don't think the box is getting hot the to relays r the p/train relay make the throttle body i think the part attatched to the sc click

ok so i hooked up my scanner and heres what i got P0443, C0247, C0050 right rear wheel speed sensor, c0550 ecu performance

that last one means you need a new ebcm. it controls the brakes, makes sense now huh?

the 443 is a evap code, the rest are abs related. bad ebcm could cause them.

is the ebcm interchangeable with one from another car like can i go to the junk yard and pull one out of another car and just put it in mine or r they vin specific or would it need to be reprogrammed .

theres no dealer bs for the ebcm, its mounted on the abs pump next to the master cylinder. snag a jy one swap it in there.

or take yours off and send it out for repair or try to repair it your self if you ok with soldering a board some. seen a vid on how to fix the one in my tahoe, looks easy enough.

you can take it off and still drive the car too.

heres a how to, a 05 should be about the same looking. How To (Un)Install EBCM

97 is once again the odd ball year. my 98 has the same master and abs pump, my regal ebcm is in the d/s kick panel, in my case and a 97 id think you need the part# to match or it wont work.

ok so i swaped out the ebcm and the abs lights and **** go off but come bak on every once in awhile when I'm driving but when i turn car off and back on later they r off again and with the fuse box making noise and my throttle body wirerless throttle contraption stoped making noise i fix that it was my oil level sensor wires were ****ed up and must of been sorting out or sumthing i put new connector on and pluged in after cleaning up the wires and whala!!
