1985 Chrysler Fifth Avenue 2.2L Turbo: Fuel System Component Guide

Understanding the 1985 Chrysler Fifth Avenue 2.2L Turbo Engine Components

The 1985 Chrysler Fifth Avenue equipped with the 2.2L turbocharged engine uses a fuel injection system rather than a traditional carburetor. Below is a breakdown of the key components in this setup:

Air & Fuel Delivery Components

• Air Control Valve – Regulates airflow into the engine.
• Throttle Body with Integral Idle Air Control (IAC) Valve – Manages throttle position and idle speed.
• Fuel Injector(s) – Delivers precise fuel amounts into the intake.
• Fuel Pressure Regulator – Maintains consistent fuel pressure.
• Fuel Rail – Distributes fuel to the injectors.

Intake & Sensor Systems

• Intake Manifold – Channels air/fuel mixture to cylinders.
• Vacuum Hoses – Control various engine functions via vacuum signals.
• Coolant Hoses – Circulate coolant for temperature management.
• Throttle Position Sensor (TPS) – Monitors throttle plate angle.
• Manifold Absolute Pressure (MAP) Sensor – Measures intake manifold pressure for fuel calculation.

Note: This vehicle does not have a carburetor; it uses electronic fuel injection. For a visual schematic, consult a factory service manual specific to the 1985 2.2L Turbo Chrysler platform.
