P24A0 Delage 3-Litre Diagnostic Trouble Code

P24A0 Delage 3-Litre code definition:
P24A0 is a kind of OBD-II Diagnostic P-Powertrain Diagnostic Trouble Code for Delage 3-Litre.

P24A0 Delage 3-Litre is described as Fuel System Too Rich, which basically means bank 1's oxygen sensor has detected a rich condition of fuel. This means there's not enough oxygen in the exhaust from too much fuel being delivered into the air and gas mixture for combusion. This is because the barometric pressure sensor is part of the MAF sensor. Sometimes, the MAF's sensing wire can accumulate and get covered with dirt, dust and/or oil residue, which can also lead to the error code.
