P1423, P1424 COLD START CONTROL

P1423, P1424 COLD START CONTROL

Description

INFOID:0000000012198002

ECM controls fuel injection timing and fuel injection quantity when engine is started with the engine cold.

This control promotes the activation of three way catalyst by heating the catalyst and reduces emissions.
