I recently installed a jdm header. The car pops the check engine light. Now the speedometer is not working along with the cars headlights and interior lights dim in and out. I wanted to know if anyone has any idea what could cause all this. Is it because of the CE light? Thanks!

 

does the car start without a problem?

 

yes it does...

 

Did you check your wire connections to the battery? Maybe one got loose when you did the header install.

 

wire connections to the battery looks good...

 

Which code is the ECU throwing? Check the obvious things first.

 

Sounds like the front engine ground is missing.

Beat me to it.

 

I got the CE light checked and the 2 codes popped up...P-0141 & P-1298.

 

These are the codes:

P0141 - Secondary Heated Oxygen Sensor (Secondary HO2S) (Sensor 2) Heater Circuit Malfunction


P1298 - Electric Load Detector (ELD) Circuit High Voltage

 

Check the underdash fuse labelled "Alternator SP Sensor." It should be fuse #15, 7.5A. It feeds all of the affected circuits. If it blows, it kills the alternator AND the alternator warning light. Seems like failure modes weren't thought out here.
