Function Explanation (DTC Detection Outline)<\/p>\n

\u2022 The PCM calculates the target fuel pressure appropriate to the engine conditions relative to the actual fuel pressure based on the fuel pressure sensor signal and provides feedback to the high pressure fuel pump control. If the difference between the actual fuel pressure and the target fuel pressure relative to the feedback amount is large, the PCM determines a malfunction in the fuel pressure sensor and stores a DTC.<\/div>\n



\n<\/a><\/p>\n

Repeatability Verification Procedure<\/p>\n

1. Warm up the engine to allow the engine coolant temperature to reach 80 \u00b0C {176 \u00b0F} or more<\/span>.<\/div>\n
2. Start the engine and leave it idling for 1 min<\/span>.<\/p>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 The target calculated by the PCM is increased and the DTC P0088:00 determination conditions are met by repeating the Step 3 operation.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
3. Shift to 1st gear and accelerate\/decelerate the vehicle to 30\u201450 km\/h {19\u201431 mph}<\/span>.<\/p>\n
\n
\n
Note<\/div>\n<\/dd>\n
\n
\u2022 Match the engine coolant temperature in the recorded freeze frame data\/snapshot data, the vehicle speed, and engine speed values to the best extent possible while driving the vehicle.<\/div>\n<\/dd>\n<\/dl>\n<\/div>\n
4. Try to reproduce the malfunction by driving the vehicle for 5 min<\/span> based on the values in the freeze frame data\/snapshot data.<\/div>\n
