Meaning of fuel system loop status

• The following information is displayed on the tester.

— Feedback stops: ECT is lower than the determined feedback zone. — Feedback operating: HO2S being used for feedback is normal. — Feedback stops: Open loop due to driving condition — Feedback stops: Open loop due to detected system fault — Feedback operating: Malfunction occurred in HO2S (rear) system

• The PCM monitors the input voltage from APP sensor No.1 when the engine is running. If the input voltage is

less than 0.35 V, the PCM determines that the APP sensor No.1 circuit input voltage is low.

ON-BOARD DIAGNOSTIC [LF]

P2123 APP sensor No.1 circuit high input

• The PCM monitors the input voltage from APP sensor No.1 when the engine is running. If the input voltage is

above 4.8 V, the PCM determines that the APP sensor No.1 circuit input voltage is high.

P2127 APP sensor No.2 circuit low input

• The PCM monitors the input voltage from APP sensor No.2 when the engine is running. If the input voltage is

less than 0.35 V, the PCM determines that the APP sensor No.2 circuit has a malfunction.

P2128 APP sensor No.2 circuit high input

• The PCM monitors the input voltage from APP sensor No.2 when the engine is running. If the input voltage is

more than 4.8 V, the PCM determines that the APP sensor No.2 circuit has a malfunction.

P2135 TP sensor No.1/No.2 voltage correlation problem

• The PCM compares the input voltage from TP sensor No.1 with the input voltage from TP sensor No.2 when the engine is running. If the difference is more than the specification, the PCM determines that there is a TP sensor No.1/No.2 voltage correlation problem.

P2138 APP sensor No.1/No.2 voltage correlation problem

• The PCM compares the input voltage from APP sensor No.1 with the input voltage from APP sensor No.2 when the engine is running. If the difference is more than the specification, the PCM determines that there is an APP sensor No.1/No.2 angle correlation problem.

P2177 Fuel system too lean at off idle

• PCM monitors short term fuel trim (SHRTFT), long term fuel trim (LONGFT) during closed loop fuel control at off-idle. If the LONGFT and the sum total of these fuel trims exceed preprogrammed criteria. PCM determines that fuel system is too lean at off-idle.

P2178 Fuel system too rich at off idle

P2187 Fuel system too lean at idle

• PCM monitors short term fuel trim (SHRTFT) and long term fuel trim (LONGFT) during closed loop fuel control at idle. If the LONGFT and the sum total of these fuel trims exceed preprogrammed criteria. PCM determines that fuel system is too lean at idle.

P2188 Fuel system too rich at idle

• PCM monitors short term fuel trim (SHRTFT), long term fuel trim (LONGFT) during closed loop fuel control at idle. If the LONGFT and the sum total of these fuel trims exceed preprogrammed criteria. PCM determines that fuel system is too rich at idle.

P2195 Front HO2S signal stuck lean

• The PCM monitors the front HO2S output when the following conditions are met. If the output is more than

1.15 for 25 s, the PCM determines that the front HO2S signal remains lean. MONITORING CONDITION

— ECT: more than 70 °C {158 °F} — Engine speed: 1,000—3,200 rpm — MAF amount: 6—80 g/s {0.80—10.58 lb/min} — Target A/F feedback system status: feedback control — Output voltage from the middle HO2S: more than 0.2 V

P2196 Front HO2S signal stuck rich

• The PCM monitors the front HO2S output current when the following conditions are met. If the output current is

less than 0.85 for 25 s, the PCM determines that the front HO2S signal remains rich. MONITORING CONDITION

P2228 BARO sensor circuit low input

• PCM monitors input voltage from BARO sensor. If input voltage is below 2.1 V, PCM determines that BARO sensor circuit has malfunction.

P2229 BARO sensor circuit high input

• PCM monitors input voltage from BARO sensor. If input voltage is above 4.0 V, PCM determines that BARO sensor circuit has malfunction.

P2401 EVAP system leak detection pump motor circuit low

• The PCM monitors pump load current (EVAP line pressure), while evaporative leak monitor is operating. If the pump load current is lower than specified, the PCM determines EVAP system leak detection pump motor circuit has a malfunction.
