#1358 of 1371 Re: Daewoo ECU and EGR [itsmechris66]
Dec 08, 2012 (9:33 am)
Sorry, that I just saw your post and now it is old. Here I go, anyway.
I think the 2000 computer may not be compatible with a 2002 engine, but I see no reason not to try (except it can be a booger getting it in and out). The computer you change to would need to know the VIN number and you may not have the necessary equipment for this, but it could function without it.
At this point, I would not suspect the computer. The computer would be the last thing I would suspect.
I don't understand your statement "codes that come in and clear". Do you mean that after a few starts the code clears itself?
More than one thing has to exist before this code will set. The computer is relying on readings from the MAP, speed, Decel Fuel Cutofff and IAC sensors, etc. Therefore, it would be good to know if this code had been set on the car the EGR came from.
If it sets the code on the current car, it should also have set a freeze frame, which can be read from a good scan tool (does not have to be the Daewoo tool, but probably better than what you find at auto parts stores).
Your replacement engine may have a defective MAP or other sensors that are affecting the EGR operation. I am thinking the MAP, IAC and TPS sensors were not changed with the engine and are all therefore suspect.
NOW, THIS IS IMPORTANT: The code clearing allows the new EGR to relearn a new pintle position. The DTC (code) must be cleared with the ignition on and with the engine off or idling to learn the new pintle position.
The proper scan tool will read the desired EGR setting and the actual setting, which could indicate a problem with the EGR, itself (will show on the freeze frame) and indicate trying still another used EGR valve.
Hope this helps. Sorry I am so late.
#1359 of 1371 1999 Leganza Brake Lights
Dec 08, 2012 (7:23 pm)
Brake lights stopped working, changed the fuse, and bulbs. Changed the switch under the pedal. Is the switch adjustable? It seems you can set the depth of the plunger by pressing in on it.
Anyway, brake lights still do not work, any ideas?

Is it possible you installed a switch that is not good? It happens. I purchased a MAP sensor once that looked new, but someone had taken it out of a car and returned it to O'Reilly for refund (they do that for shops) and it went back into circulation and of course, I got it.
I would use a volt-ohm meter to check for continuity in both the old and the new switch. Inexpensive volt-ohm meters cost so little that everyone should have one and learn how to use it.
I see no adjustment in the switch; it is a simple switch that should close contacts when it is out.
Do the back-up lights work? If they do, then the ground is probably good, but I would check for a solid ground (Black wire), anyway. The rear window stop lamp has its own ground. Does it work? If it does, that would lead to suspecting the brake light ground.
The ground for the brake lamps is below the tail lamp on the driver's side, in the trunk.
The ground for the window center stop lamp is under the front driver's seat.
I hope this helps. If it doesn't, please post again.

#1363 of 1371 Re: Oil In Coolant - 2000 Daewoo Leganza [daewooowner1]
Feb 19, 2013 (2:59 pm)
Yikes, when I bought a Nubira, the coolant cap was clicking and not coming loose, and neither my mechanic or I thought to undue a radiator hose, shame on both of us!! I think the seller snookered me! After I bought the car and another mechanic broke the cap off, there was oil in coolant!! Head gasket didn't fix it, mechanic said it probably got over heated and there was a crack in the block so we got a junkyard engine. Also for daewoo owners, nubira, watch for that water pump bypass hose leaking, it appears to be the water pump leaking but its just a hose. Avai in Puerto Rico via a supplier or the local guys have a J shaped hose that will fit. Starter goes about 90,000 miles on the 2 liter nubira, it starts turning over slowly b4 it goes.
#1364 of 1371 bad fuel pump
Feb 21, 2013 (10:07 pm)
hard starting, cranking 3 times to start, engine lite finally came on---
1. shows problem with coil--changed
2. problem with O2 in block--- changed.
3. did a fuel pressure check on original pump--- replaced with new fuel pump
3000 miles later had same problems did a fuel pump pressure test again and it would not hold pressure.
upon removing 3000 mile pump it was hot to the touch so it must have burnt out.
just installed another new one (12000 miles/ 1 year warantee)
QUESTION will it happen again or is there still something wrong
#1365 of 1371 2001 Daewoo Leganza right turn signal stays on
Apr 22, 2013 (9:11 am)
My right turn signal (not always) stays on. I press lock/unlock on the remote several times and it turns off just to come back on; at no scheduled time of course. At the same time the temp gauge went up to over 3/4 on the dial when it usually shows below 1/2. I was using the Cruise Control at the time and was traveling around 70 MPH on the highway. I don't know if this helps, but also the alarm goes off by a simple 10 MPH spring breeze as well. Like I said I don't know if they are all related. Just do not want to leave a single description out in order to fully diagnose/solve the issue. Ever since the issue with the temp gauge, that particular issue has not returned. The right turn signal light issue has reoccured one other time. I have a minor length trip planned in one week so I need help with this soon please. Any questions on this please ask. To not leave anything out: When the turn signal thing happens, all the lights involved with the right side directional stay on when it happens. I replaced the right rear directional bulb but the problem persisted. I changed the 15A fuse as well. The old fuse wasn't even blown. Thank you
