paulo57509 Posted August 10, 2023 Share Posted August 10, 2023 These are the only diagrams/procedures I can find in the 1998 Lexus manual.聽 It should be identical for the 1999 model year.

Slavo_S2k Posted August 18, 2023 Author Share Posted August 18, 2023 Thanks, that's what I meant! Do you perhaps know how the car would react if I connect this wrong ? Will there be any errors ? Quote Link to comment Share on other sites More sharing options...
paulo57509 Posted August 22, 2023 Share Posted August 22, 2023 I don't really know how the engine would react. I do know that some vehicles will set the check engine light for a loose fuel filler cap.聽 Might be the same with an incorrectly connected evap cannister. Perhaps having the vacuum lines connected incorrectly at the evap cannister, example - having a vacuum line that's supposed to be connected to a closed valve but connected to open to the air would be seen as a vacuum leak and set a trouble code.

Slavo_S2k Posted August 24, 2023 Author Share Posted August 24, 2023 Interesting,聽 Many times during the repair, the car was started without the canister plugged in and was able to run normally for up to 20 minutes without an error. 聽 Quote Link to comment Share on other sites More sharing options...
