DTC P244A:00 |
Exhaust gas pressure sensor No.2 range/performance problem |
|---|---|
|
DETECTION CONDITION
|
• With the following conditions met, a condition has continued for 7 s in which the difference in the pressure before and after passing the diesel particulate filter is less than the specified value.
MONITORING CONDITIONS
Diagnostic support note
• This is a continuous monitor (other).
• The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM.

• FREEZE FRAME DATA/Snapshot data is available.
• DTC is stored in the PCM memory.
|
|
FAIL-SAFE FUNCTION
|
• PCM restricts engine torque.
• Inhibits the auto diesel particulate filter regeneration control.
• Inhibits the compulsory diesel particulate filter regeneration control.
• Inhibits the EGR control.
• Inhibits engine-stop by operating the i-stop function.
|
|
POSSIBLE CAUSE
|
• Erratic signal to PCM
• Exhaust gas leakage from exhaust system
• Pipe between exhaust gas pressure sensor No.2 and catalytic converter restriction and/or damaged or improper routing
• Exhaust gas pressure sensor No.2 malfunction
• Catalytic converter or diesel particulate filter malfunction (deformation, damage)
