Engine ECM problem since I changed camshaft

Post by Merocks »

Hello,
So I just completed second timing belt change at 123000 miles on Leganza, and finally changed my camshaft sensor. I paid like 90 bucks for it off of ebay and had mechanic change it along with timing belt, thermometer, and water pump. Car works fine, but gas consumption seems to have increased, and now I am getting error message that my ECM is no longer working correctly. Could the two be linked? Any feedback would be highly appreciated.
Thanks!

actually I didnt...the one that's listed here has some steps, but then it says to follow a link to do the procedure, but that link is dead. I tried searching for it on web, but couldnt find it...Do you have the complete procedure?
Cheers!

turn ign on for 5sec
start engine in park/neutral
allow the engine to run until operating temp is reached

it's in both the leganza and lanos manual i have

>merocks
it might be a good idea to reset the ecu by leaving the battery unplugged for 10mins just to make sure you are starting on a clean slate before you do the re-learn

Some time ago I came across a technical service bulletin TSB-008-01 here on our forum saying that crankshaft & camshaft have to be electronically aligned when they are "disturbed". It's so called TEC Tooth Error Correction procedure. I don't know if this will fix your problem.

Hope it helps,

The Scan 100 Scan Tool that needs to be used here for Tooth Error Correction, I am wondering can one use any Scan Tool? I would have to buy one, but they are expensive and I want to make sure I have the right one...

I have two different consumer based scan tools and nether has any function like that. none of the others that I've looked at do either.you'd almost have to find out if any of the Snap-on scanners have the function but those are in the $1000's.
