code 36

I have an 87 Camaro that I replace the original 305 with a 350. Now I am getting a code 36. I read that it is a burn off relay failure. Where/what is this relay ?

Re: code 36

I don't recall where it is. The burn-off relay puts a high current through the hot-wire element on the Mass Air Flow sensor, for a second, to burn away any oil deposits that build up on the wire. I believe this happens just prior to starting.

Check the connections to the MAF sensor. The sockets can become sprung and fit loosely causing problems like this. I've personally experienced a code that translated to "MAF voltage high" that was caused by sprung terminals in the MAF connector.

You can use a small pick-probe or screwdriver to squeeze them shut a tad and improve the connection. A little light sanding with a rolled up piece of sandpaper would also help. I'd recommend doping it with dielectric grease once you get it all refurbished.

Re: code 36

The Burn-Off Relay is located under the hood on the drivers side inner fender sorta back towards the firewall area.
Look for a grouping of three(3)~four(4) relays mounted together - it is the one closest to the outer fender or towards you in that group.
Relay has four connections, two 12+vdc, (D & E), one Grounding to ECM (F) and the output to the MAF (A).
Check for voltage (12+vdc) at the D & E connections with the Key off to be sure it is getting voltage.
Grounding the F connection will toggle the relay to see if it is pulling in. You can ground through the black wire at the relay or on terminal D12 on the ECM.

Like 'dnult' said - check for loose connections first, as these relays seldom fail.

Re: code 36

The after burn relay is on the driver's side firewall right next to the brake power booster. I also agree that it is most likely not the relay that is causing the problem. I looked in my troubleshooting book for a code 36 and is not listed as a valid engine code......at least not in my book for a 350 or 305 engine.

Re: code 36

I also checked my book and could not find a code 36. I found it on the internet. I will check the voltage. Thanks for the help guys.
