DTC P2453:00 [MZR-CD 2.2]
id0102f3153700
|
DTC P2453:00 |
Exhaust gas pressure sensor circuit range/performance problem |
|---|---|
|
DETECTION CONDITION
|
• The PCM monitors the differential pressure by the exhaust gas pressure sensor circuit voltage. If the differential pressure between the maximum and minimum value of the exhaust gas pressure sensor is more than 100 kPa {1.02 kgf/cm2, 14.50 psi}, the PCM determines that there is a malfunction in the exhaust gas pressure sensor.
Diagnostic support note
• The MIL does not illuminate.
• FREEZE FRAME DATA (Mode 2)/Snapshot data is not available.
• The DTC is not stored in the PCM memory.
|
|
POSSIBLE CAUSE
|
• Exhaust gas pressure sensor connector or terminals malfunction
• Exhaust gas pressure sensor malfunction
• PCM connector or terminals malfunction
• PCM malfunction
|
