2000 Deawoo Nubira P1441 and P0128 Error: What Components Need Replacement?
Hi everyone, I'm working on a 2000 Deawoo Nubira that has triggered two diagnostic trouble codes: P1441 and P0120. These codes appeared previously, and in the past, tightening the gas cap resolved the issue temporarily. However, this time the check engine light remains on after attempting that fix. I'm looking for clear guidance on which components should be inspected or replaced to resolve these codes. Any detailed input from experienced users would be greatly appreciated. Thanks in advance!
The P1441 code typically points to a faulty oxygen sensor or evaporative system leak, while P0128 suggests an engine coolant temperature sensor issue or poor thermostat performance. It's not necessarily one component—both should be checked and possibly replaced depending on the vehicle's history and test results.
