Was wondering if anyone can help me out. I installed an lt1 maf/translator I bought from someone on the board today to see if it will clear up some driveability issues and a code 34 comes up after 10 seconds of idling. Clear the code, plug the oe maf, code goes away. Plug translator back in code comes back. Power and grounds are good with less than .005 voltage drop through each of the wires. I noticed that with the translator setup hooked up, the af reading on the scanmaster rises with throttle application, koeo. Where as the old maf reads 04 regardless of throttle position. This tells me that the ecm is not picking up a maf signal and using a substitute value. With the translator lid open, i have the following voltage readings at the solder joints from each of the wires:
Pink: 12.3 (B+)
Blk: .015 (Ground)
Grn: 5.0 (Ref?)
Yellow .8v (maf signal?)
Blk: .010 (Ground)
Pink: 12.2 (B+)
Im beginning to think there are issues with the translator box. The .8v seems to be the maf reading but is somehow not getting back to the ecm. I have the pins out of the connectors and am positive they have good connection. Any help would be appreciated. Thanks in advance.
Forgot to mention switches are set to ON,ON,ON,OFF. Base 3. WOT 0.
