Tomorro (wednesday) i will be dedicating the entire day to eliminating my last 4 check engine light codes. I could use some help from a rotary expert. I dont know anyone around that is familiar with a s5 t2. Just PM me if you can help, i'll get you some directions to the shop. I'll have pretty much any tool needed. I would also like to have someone just look over the car and tell me if anything looks out of place or can clarify a few things for me. I dont have much money but I would be willing to cover lunch or something. Im pretty sure my codes left are:

9,12 , 13, 42


Code 9 looks like may be a loose wire issue

Code 12 is prolly a bad sensor or maybe even loose connector as well (anyone got a spare to test with?)

Code 13 either bad map or wrong one, I found this one in a box of parts but no idea what it went to, i only grabbed it cuz i knew my car didnt have one anywhere around.

Code 42 im guessing thats the solenoid on top of the intake manifold that connects a hose to the intercooler (brittle wire finally broke, going to try resoldering it tomorrow) (got a spare but looks slightly different)


Anyone got any spare sensors to try? If I can get those codes knocked out tomorrow, i'll go register/inspect the car and it will finally be on the roads again.

heres a pic of the sensor that had a wire break. I just held the wires together and checked the CEL codes. Im guessing its my code 42. Anyone know for sure?

Ok I got some work done and now I am down to 2 CEL codes. TPS Sensor was just loose. Water temp sensor had the pins in the clip so they were not making connection. Leaving:

Code 13 and 42.

Map and some solenoid. I fixed the solenoid on the TMIC but that did nothing.

This car had no map when I got it, I have seen a few engine bays and they all had a map on the strut tower. I just grabbed one from a box of rx7 parts and assumed they were all the same (same box I got all my other parts from also)

I guess I need a N370 map now.

After tons of looking at diagrams/fsm/alldata I couldnt find the "I" "J" solenoids in the diagrams but then I found a misc sensor under the oil fill tube that had no connector but 2 vacuum hoses going to it. I assume this is my code 42. Only thing is I cannot find a clip for it anywhere in the engine bay. Does it connect to the main harness from ecu -> enginebay or on the driver's side harness? I can't find any info on the part numbers either.

The numbers on the sensor (pictured below (bottom sensor)) are:
N370
136200-0311


I have 2 sensors that I grabbed from the pile of parts just in case. they are the top sensors. Someone mentioned a Rich/Lean sensor and I see them on alot of strut towers but I have no clip on the harness for them. Needed in a S5?

Didnt find any use for the last sensor (similar to the one that broke as shown above but hoses are 90 degree on this one and mine are 180.





Sorry for the long post.

the one with the pink reddish thing the connector is from engine hardness

The one on the left is the factory boost control solenoid.

The middle one is the ABSV (air bypass solenoid valve) -- Used for supplementing the idle when doing things like running the A/C and turning w/ the power steering; both of which drag the engine down.

The one on the right is basic idle mixture control. Mounted to the passenger side shock tower area.

sensors on the right and bottom have no clip that I could find on this engine harness. Could I possibly have a wrong engine harness? Again, I found this engine harness in a box of parts. It plugged into the ecu fine and seems to have every connector I needed except those 2. It also has 2 extra solenoid clips for those solenoids under the oil fill tube. I have seen 4 soleniods in a row on my friend's na fc but mine only has 3 solenoids with colored dots. I just plugged in 3 matching connectors on the harness and still have 2 left over.

I just found my memory card for my camera, i'll try to get some new pics today.
