EJ Swap in a Day

alright....spent the day at the junkyard yesterday. (actually....spent the day driving to/from the yard, only spent about an hour there...but whatever). Got some goodies for my car, but a couple things for this one too. most importantly, I pulled an alternator and wiring pigtail from a '91 legacy. plugged that in, and now it charges wonderfully. So I drove it to work, and delivered in it the whole night (alright....slow night, only put like 40 miles on it). works great, love the power, still got a few gremlins, but she's coming along nicely.

 

although, I quickly notice how spoiled I've been with the way my car handles......one little noodle of a sway bar, stock springs and 185/70r13 tires really takes some adjusting (compared to the XT6 bars, GC coilovers, poly bushings and 215/45r17 performance tires on my loyale)!

 

also, got the plastic engine cover from that same legacy, you know the one, that says subaru 16v MPFI something. nice little factory touch.

 

still needs a different speedometer....that's just a matter of me being lazy. also need a rear 02 sensor, and a muffler (nice sound, but it gets obnoxious in a hurry).

 

I meant to plug in my code reader (OBD II engine, still has diagnostic port) to see what code(s) it's throwing. would be sweet if it's just the rear 02.....but I doubt it.

 

I also need to get out the zip ties and go to town under the dash......now that I know things work, I need to clean it up.....a lot!

 

 

this is all still with the evap line plugged and the gas cap loose.....so I haven't worked on the vapor separator.

one other engine light would be for the gas tank pressure since the cap is loose.

 

Congrats on the swap and it's fine progress. You have definately thrown down the gaunlet in terms of swaps.

 

Maybe next year at WCSS11 we can see we can finish a swap at the show...:headbang: This would obviously require a lot of prep work to make it happen.

 

Would like to participate in that but I am couting on having to swap other things by then... like diapers. (fingers crossed) :popcorn::clap:.

well, I plugged in the code reader yesterday.....and it had 9 codes in there, from a number of different things. I cleared them, and only one came back. P0105, Manifold Absolute Pressure/Barometric Pressure Circuit.

 

so, some research is in order to figure out wtf that means...

 

 

 

no fuel tank pressure sensor, so no code from the gas cap.

its looking for the MAP sensor. either that or the MAP sensor is bad.

as far as I've been able to tell, the MAP sensor is a backup for the MAF.

 

luckily....I've got an extra one....somewhere. I've put about 150 miles on it in the last few days. still runs great, and reads about 1/2 tank. maybe after work tonight I'll fill it up and see what kind of mileage I've been getting.

Does anyone know if the MAP sensor on this motor does anything but check the egr?

 

usually, the MAP sensor takes the intake air readings, does the same job as the MAF but works off of pressure, not flow rates. i know some of the older ej engines had one or the other, and a few had both if i remember correctly.

so....as it turns out....the MAP sensor works fine, as long as it's plugged in theyareontome.gif

 

yea, went to replace it, and realized the plug was in the right place, but not plugged in all the way. plugged it in, and it stopped throwing that code.

 

 

now I'm getting 02 sensor heater circuit (still no rear sensor...). AT diagnostic circuit (this one confuses me a bit...as the donor car wasn't even an AT.....so some research is in order). knock sensor 1 circuit and EGR (not sure what the cause of these 2 could be, I'll check wiring first....but I don't really know).

 

 

 

also, got gas yesterday. and it got about 3mpg better than my loyale does in similar driving (delivering in town...all under 40 mph....loyale gets 17 and this GL got about 20. the loyale gets 26-27 on the highway...so this car should do quite well).

 

um..not much else to report. fixed the speedo, fixed the radio wiring (PO did a crappy job of putting the stock unit back in), re-wired the oil light so it actually works (there is a light in the dash for the DLs that didn't have a gauge. so I just wired the EJ sender to it, and it works perfectly! I'll probably do this on my car).
