Title: Few vcds checks... Post by: masterj on January 05, 2012, 03:02:31 PM Hey guys! :)
Today I was doing some idle vcds block checks and I have few questions now.. KNOCK SENSORS: On idle they really suppose to give 0.400 - 1.400 V ?? VCDS shows me 0.2xx 0.4xx 0.3xx 0.2xx volts. Does that mean that I have to check my knock sensors/connectors or they look ok to you? Could someone give me screenshot of theyr coltages at idle? PRECAT O2 SENSOR AGING: Now I can not remember exact group of this, but the test never finishes. I mean I go to basic settings hold ~2800 RPM, test starts and never finishes. Does that mean that my front o2 sensor needs inspection? (my postcat o2 sensor is coded out) AFTERCAT DELTA LAMBDA (GROUP 37): Test in basic settings also never finishes unless I go back to measurement block. SENSOR HEATING (GROUP 41): Could someone check if at idle their o2 sensor heating goes on and off every second? I thought that it is suppose to change only on during system mode change (idle/part throttle/wot/enrich) EVAP: In EVAP measurement block my "lambda regulator during tbv diagnosis" is -7,8% (limits: -10% +10%). So does that mean that my evap container is nearly full?? This number never changes and always stays -7.8%, even if I start engine next day. Waiting for your input :) |
