P027E 2016 Honda CR-V Code - Cold Start Air Fuel Ratio Control System Command Lean

Quick Answer

The cold start emission reduction strategy controls air-fuel ratio to lean when the engine is started under cold conditions to lower the emission while the catalyst is not warmed up enough. Common causes include Faulty Powertrain Control Module (PCM), Powertrain Control Module harness is open or shorted, Powertrain Control Module circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P027E 2016 Honda CR-V Description

The cold start emission reduction strategy controls air-fuel ratio to lean when the engine is started under cold conditions to lower the emission while the catalyst is not warmed up enough. If the commanded air-fuel ratio is too lean or too rich compared to the target air-fuel ratio, the Powertrain Control Module (PCM) detects a malfunction and stores a Diagnostic Trouble Code (DTC).
