RS VR6 0 Posted February 27, 2007 Got this code ramdomly today. It showed up twice as I was in traffic. I got no real answer searching. Where is the O2 sensor heater relay(Z19)? Lambda Sensor, G39 - Signal to B+ - Signal to ground - No change in signal Possible Fault Conditions Open circuit to J220 Lambda sensor heater (Z19) faulty Where is it located? Fuse for Z19 blown G39 faulty, recently replaced Signal wire short to ground or shielding Ignition system failure Intake leak after mass air flow sensor (G70) Leak in exhaust system before catalysts Ground wire between pin 10 (which is pin 10?) on J220 and engine block open circuit Quote Share this post Link to post Share on other sites

RS VR6 0 Posted February 27, 2007 I checked the wiring last night...everything seemed fine. Lol...just remembered...for the Z19 relay location, all I have to do is perform the output test on my Vag Com. If it clicks its still good. Quote Share this post Link to post Share on other sites
