^ Freeze Frame | When the check engine light turn on, the ECU determines the error based on several engine operating conditions and stores it in what’s called a OBDII freeze frame. The data stored in Freeze Frame is usually recorded when a system fails the first time for two consecutive trip faults. Freeze Frame data will only be overwritten by a different fault with a higher priority. | ^ Freeze Frame | When the check engine light turn on, the ECU determines the error based on several engine operating conditions and stores it in what’s called a OBDII freeze frame.

- | ^ Closed loop mode | | | + | ^ Fuel trim | Fuel trim is an adaptive strategy that adjusts fuel injector pulse width (open time) to adapt to wear, defects, or changes in the system. There is a short term fuel trim STFT and a long term fuel trim LTFT strategy. |
- | ^ Misfire | + | ^ Closed loop mode | In closed loop mode the vehicle is adjusting air/fuel mixtures based on the real time results it’s getting from the oxygen sensors. Engine stays in open loop for a few minutes, until oxygen sensor reaches its working temperature, |

+ | ^ Bank 1 and 2 | There are a number of OBD-II trouble codes that refer to either Bank 1 or Bank 2. Bank 1 refers to the side of the engine that has the #1 cylinder, Bank 2 is the opposite side of the engine. | ||
