O2 VALUE(ACTUAL)(%) O2 VALUE(BANK 1)(%) O2 VALUE(BANK 2)(%) ______________________________________ (range not available) Indicates the operation and Short-term correction of the fuel delivery for the stated cylinders. They show whether the ECM is commanding a rich or lean mixture. A number above 0% indicates that the ECM has commanded a temporary rich mixture correction. A number below 0% indicates that the ECM has commanded a temporary lean mixture correction.

131 Data Parameters Gas Engine Parameters These Short-term correction numbers are also used by the ECM to learn a fuel correction pattern or trend and are stored in the learned mixture or lambda values. Fuel correction operates only in closed loop. In open loop, a fixed value displays. OIL TEMPERATURE(°C/°F) ___________________________________ (range not available) Indicates engine oil temperature in degrees. OPERATING MODE _________________________________________ (range not available) Indicates the current operating mode of the engine system. OVERRUN_____________________________________________________ (range YES/NO) Indicates whether the current engine operating condition is overrun. PARK/NEUTRAL POSITION range P-N-/-R-DL) Indicates whether an automatic transmission is in park or neutral, or in one of the drive ranges. It should read P-N if the transmission is in either park or neutral R-DL if the transmission is in any forward gear or in reverse. PARK/NEUTRAL POSITION _________________________________ (range P/N NOT P/N) Indicates whether an automatic transmission is in park or neutral (reads P/N), or in one of the drive ranges (reads NOT P/N).
