6E1-44 ELECTRONIC FUEL INJECTION SYSTEM (G13/G16 ENGINE WITHOUT WU TWC)
SYMPTOM
Improper engine D Maladjusted accelerator cable play
idle speed
D Clogged MAP sensor vacuum passage
D Vacuum leaks (or air inhaled) in air intake system
D Maladjusted TP sensor installation angle
D Faulty idle air control system
D Faulty evaporative emission control system
D Faulty A/C signal circuits (if equipped)
D Faulty electric load signal circuit
D Fuel pressure out of specification
D Faulty injector(s)
D Poor performance of IAT sensor, ECT sensor or
D Faulty ECM (PCM)
NOTE:
D If engine idle speed lowers below specification only when electric load is applied (e.g. headlight ON),
check idle air control system first.
D With A/T model, if engine idle speed lowers below specification only when shifted to "R", "D", "2" or
"L" range, check if "R", "D", "2" or "L" signal (for 3 A/T) or transmission range signal from TCM (for 4
A/T) is inputted to ECM (PCM) first.
Engine has no or D Maladjusted accelerator cable play
poor power
D Faulty EGR system (if equipped)
D Fuel pressure out of specification
D Fuel injector(s)
D Poor performance of TP sensor, IAT sensor, ECT
D Faulty ECM (PCM)
Engine hesitates D Clogged MAP sensor vacuum passage
when accelerating D Faulty EGR system (if equipped)
D Fuel pressure out of specification
D Fuel injector(s)
D Poor performance of TP sensor, IAT sensor, ECT
D Faulty ECM (PCM)
POSSIBLE CAUSE
(if equipped)
MAP sensor
(Low fuel pressure)
sensor or MAP sensor
(Low fuel pressure)
sensor or MAP sensor
