Hi
I`ve got some codes
#29 EAS electrical fault (ODM)
#41 EST OPEN
#84 that because I`ve disconected CAGS I think

what are the other two?

 

DTC 29 = Secondary Air Injection (AIR) pump circuit

Check the fuse to the AIR pump. It is common for the AIR pumps to get moisture in them and short out.

DTC 41 = Ignition Control (IC) circuit (open circuit)

Check the connections at the ignition coil module (ICM). If your car is running, the problem is intermittent.

DTC 84 = Skip shift solenoid circuit (manual transmission)

You seen to already know about this one. Search the web or ProjectTransam for a way to get rid of the code with it disconnected.

There is a correct listing of 94-97 DTCs on my Tech Page.

 

There is a list of OBD-I codes at the end of my online ScanMaster writeup.

DTC 84 is Skip Shift.

DTC 29 is AIR pump circuit. Most likely the fuse is blown. If you have intentionally disconnected the AIR pump, you need to be sure there is a good fuse in the circuit. That will eliminate the code.

DTC 41 is Ignition Control Circuit, open or shorted circuit. If the engine is running, this is a "stored" code, because the PCM kills the fuel system if the code is active. This involves the power supply to the coil and to the Ignition Control module. There is a fairly detailed diagnostic procedure in the factory manual. I suspect that you will find it on Rob/Shoebox's Tech Resource Website.

 

thanks guys

I`ve changed fuse for air pump.no more 29

I`ve deleted the codes but they are now back : 41, 32 ( egr system fault) and 84.

my car is runnig so whats with 41 code?
shpould I look for some short or something?

I`ve got 32 egr fault , I can smeel exhaust and/or fuel inside the car mhm am gonna do intake gasket leak next week so I think I`ll get rid of egr and air.

 

I`ve downloaded `95 camaro manual from Shoebox site but I couldnt find that procedure in it. Where is it?

 

Perhaps you downloaded the owner's manual. The procedure is in the service manual (for which there is no download).

Normally with a code 41, your engine will not run. The diagnostics are geared to that, so they won't really be much help. I would check all connections at the coil and coil module. Make sure there is no corrosion and they are tight. Also check the IGN fuse in the underhood fuse panel. Take it out and wipe it off and/or swap it with another of the same size.
