Hello,
I have been following a thread in the "support" forum, however it wont let me post there yet as i am apparently not yet verified. anyway. here's the background. GF's car popped the P2404 code a few years ago. She took it to local mechanic who replaced the LDP twice, and of course that didn't solve the problem. Well, somehow they made it pass smog, but of course the check engine light was never off for long. Come 2 years later, vehicle registration is due again, and hence we have to smog it again.
So far I have done the following.
1) replaced J757 fuse
2) verified resistance in LDP pump was as specified in manual.
3) i am currently renting a Ross Tech cable. I have run the 071 test multiple times. First few times it aborted. A couple weeks later, i was able to work on car again. Performed the 071 test with the N80 line crimped. Aborted the test 2 times. Next I ran without the crimp on the N80, and it passed. So now i'm even more confused.
here's the autoscan. any advice is appreciated.
