2015-10-20· Fuel trim includes short term fuel trim and long term fuel trim. “Short term fuel trim” is the short-term fuel compensation used to maintain the mixture ratio at its theoretical value. The signal from air fuel ratio (A/F) sensor 1 indicates whether the mixture ratio is RICH or LEAN compared to the theoretical value. The signal then triggers a reduction in fuel volume if the mixture ratio ...
Common Problems. The limp mode can be caused by a lot of different issues and sensors. For example, the limp mode can be caused by a dirty MAF sensor, which takes 15 minutes to replace.
