P0424

DTC P0424, sometimes indicated as P042400 is an OBD diagnostic trouble code indicating a generic fault with the vehicle powertrain (i.e. engine and gearbox). This code identifies an error with the auxiliary emissions system causing heated catalyst temperature below threshold (bank 1).

This code is set when the engine computer detects that the temperature of the catalytic converter on Bank 1 is below its threshold.
There are a few possible causes for this code, including a defective catalytic converter, a problem with the engine cooling system, or a problem with the exhaust system.
If this code is set, it is recommended that the vehicle be inspected by a qualified technician to determine the cause.

• P0424: Heated Catalyst Temperature Below Threshold (Bank 1)
• P0424: Heated Catalyst Temperature Below Threshold Bank 1
• P0424: Heated Catalyst Temp Below Threshold (Bank 1)
• P0424: Heated catalytic converter, bank 1 – temperature below threshold
• P0424 00: Efficiency of the pre-catalyst (cylinder row 1) per mafa
• P0424 00: Heated catalytic converter, bank 1 - temperature below threshold
