DTC P1283-00: Cold Start Fuel Injection Control Performance #1; DTC P1284-00: Cold Start Fuel Injection Control Performance #2; DTC P1285-00: Cold Start Fuel Injection Control Performance #3; DTC P1286-00: Cold Start Fuel Injection Control Performance #4 [08/2021 - ]: Description

WARNING: This page is about a different car, the 2024 Lexus ES 250, 2023 Lexus ES 250, 2022 Lexus ES 250, and 2021 Lexus ES 250. However, it is still accessible from the selected car via links, so may be relevant.

To improve emissions immediately after a cold start, cold start multi pulse fuel injection control is performed which divides a single pulse of the direct fuel injector into several smaller pulses.
