That code reader won't work on an S5 (FD yes, FC no). Again, there is a check connector (plug connected to nothing) near the lead coil w/only one wire and the wire is Orange.

 

Okay I got 188112 for the code

 

Or 8 quick flashes and 1 held flash and 2 quick flashes the reply before this one just shows the pattern of the flashes.

 

Check the wireing and vacuum line to maps.
Make sure its plugged in to the correct spot

 

RX7 FD & Series 5 Error Codes

 

I have code(s) 8 10 12 18 now that I know this which code should I fix first to get the car to run?

The picture is just the process on how I watched the codes

 

See the codes I got from the car it looks like my afm is broken or has a short in the wire and my throttle control has a short what should I try to fix first?

 

Was the AFM connected when you checked for codes?

 

Yez

 

You stated the OMP was shorting out the Br/W wire. Was the OMP connected to the car when you pulled codes? If it was then unplug it and check for codes once again, but expect the error codes for the OMP to show up as expected since it was unplugged.

 

Omp code went away now all thats left is the afm and throttle codes

 

You need to focus on the Br/W wire having 5 volts w/key to on as already mentioned. Is it true that when you unplugged the OMP that the voltage returned to 5 volts but w/the OMP plugged in it does not have the correct voltage? If this is so then there is a problem w/the wiring/connector to the OMP or the OMP itself.

 

Yes that was true but I fixed the replaced the omp and the omp lines and there's no problems there my problem is at the afms b/w and the tps b/w wire. Could there be a short in the wiring harness itself?

 

Don't you mean Br/W wire? And why do you believe you have a problem on this wire besides the voltage on this wire not being 5 volts or is it 5 volts? Which is it? If you have 5 volts on this wire then your problem is caused by something else and not this particular wire (there are other wires running to both of the sensors you mentioned).

 

Its not at 5 volts and I do mean the br/w wire

 

I thought you said you pulled the plug off the OMP and the 5 volts returned. No?

 

It returned to 5 volt on the br/w going "to" the omp but not at the afm it doesn't make sence to me at all.

 

Does it have 5 volts at the TPS and Boost Sensor in addition to the OMP?

 

No just at the omp the tps has a low reading as well as the afm and im not sure about the boost sensor because I have a non turbo

 

The Boost Sensor and Pressure Sensor are the same thing. Again, pull the plug to all of these sensors (all of them and there are four of them) and check the plugs to each w/key to on and see what's up.
