Mode B (Measurement Of Reference Pressure For Setting The Target Negative Pressure)
WARNING: This page is about a different variant/trim than selected.
- Purpose: Judge the reference pressure stability.
Judge as NG when the following conditions are established.
JUDGMENT VALUEMalfunction Criteria Threshold Value DTC |Pressure sensor maximum output value - Pressure sensor minimum output value| > 0.3 kPa (2.355 mmHg, 0.1 inHg) P2404 - Purpose: Judge whether the reference pressure is within the normal range, and detect the vacuum pump and orifice malfunctions.
Judge as NG when the following conditions are established.
