The original daewootech forum

I myself am new to daewoos and "sensor technology", but if your car has given the code but now responds well, would it be worth doing a ECU reset then the IACV relearn procedure? Sounds like you're not far from fixing this though. I'm having similar (not as severe) issues with my wifes Tacuma, I su...

The GM dealer does not want to fix the car. Independent mechanics don't have the necessary scan tools. Three of them gave me hope initially but at the end their tools does not perform the relearn. Now I am coming up with my own make-shift relearn procedure. My friend have this software that is suppo...

Hi Daniel, No, I did not try an ECU update because I do not know how. I think writing anything to a Daewoo ECU requires a Scan-100 or a Tech2 tool. If you know any other method I may also use it to get my ECU to relearn crank variation. I tried a different ECU with no effect though. However, later I...

Finally, the ECU threw the long awaited P1336 (Crankshaft Variation Relearn). Although my ECU is an obtuse one, it is still functioning. The funny but understandable thing is that after the code, the high idle and the rich mixture conditions are gone. The car is running smoothly. Now I have to find ...

Well, it turned out that the reason why I could not pump any gas is that the vent-valve-side of the Canister was clogged. I replaced the Canister. Now I can pump gas again. How on earth the car was passing the asynchronous self EVAP test with a clogged canister is beyond me. High idle saga continues...

Does anybody know whether there exist a scan tool that can do Crankshaft variation learning or ecu flashing on 2000 Lanos. Scan-100 Tool is hard to find in the US. Is Tech2 able to do that? These are expensive tools usually owned by the Daewoo dealerships in a parallel universe. Does anybody know a ...

Yeah, I did not read the footer in your posts. The engine type is indicated there. I automatically assumed you are talking about a Lanos 1.6.

Good Luck.

Well, I am not sure I understood your question because the vacuum lines in my car are on the manifold side. If you look at the first picture: the one on the right is the EVAP (purge valve), the middle one is cancelled and the left one is the MAP. There is also a PCV line seen on the second picture g...

Thank you for your interest in replying. The way I test for that is through OBDII. While the ignition is on but the car is not running, if I control the throttle position manually, this is reflected by the OBDII reading proportionally. Therefore, I conclude that the ECU is aware of the throttle beha...

Hello, I would like to thank in advance whoever spends his/her time reading and maybe responding to my post. Let me first give you a brief historical background to my problem. I initially got a crankshaft position sensor (CPS) error which I resolved with a new sensor. However, just after the replace...

We changed the sensor yesterday. I have a friend who is way more experienced than I am. He did most of the work. Working around a small space, it took us long time to reach to the sensor. If I do it again I would go ahead and replace the timing belt etc. Removing only the upper timing belt cover jus...

My check engine light also threw me a 0342, so I am trying to change the camshaft position sensor. I just learned that it is under the upper timing belt cover between the camshaft gears. According to the manual touching anything related to timing belt requires removing million parts including right ...
