Carbureted Fuel System GENERAL INFORMATION On these vehicles, the engine management system is considered part of the emission control system. The major components include the carburetor(s), feedback control system, the air injection system, a throttle control system and the EGR system. The system consists of sensors and switches that feed information to the Electronic Control Unit (ECU), which will then operate several solenoid valves to maintain the ideal air/fuel ratio under all conditions. As useful as the tests found in this section are, the first step in repair or service to engine management systems is still to gain as much information as possible about the problem; when and under what conditions it occurs. At highway speed? At idle only? Only under heavy load or hard acceleration? Wet weather? Defining the problem will eliminate many systems from consideration and possibly point to the affected system. Before diving into an extended electrical diagnosis, take the time to review the basics. Check every vacuum line for cracks or leaks. Check every electrical connector for corrosion or loose pins. Quite often, simply unplugging and reconnecting a connector will break up corrosion on the pins and restore the circuit. Watch out for poor grounds, particularly if the car has experienced major bodywork. COMPONENT TESTING Air Injection System The purpose of this system is to supply oxygen to the exhaust stream at a point in the exhaust manifold that is hot enough to burn off some of the hydrocarbon emissions. The main component is an air suction valve. The valve is spring loaded to stay closed, with engine vacuum supplied to a diaphragm that reduces the spring pressure and allows the reeds to open. The ECU regulates the engine vacuum to the diaphragm by operating a solenoid valve. 1. With the engine at normal operating temperature and at idle, remove the air cleaner and listen for a bubbling sound at the air suction port. There should be no sound at idle, meaning the air suction valve is closed. 2. If the noise is heard at the air suction port, disconnect the vacuum hose at the air suction valve and connect a vacuum gauge to the hose. There should be no vacuum. If there is vacuum and the noise stops, the problem is in the control system. If there is no vacuum and the bubbling sound is still there, the air suction valve is defective and must be replaced. 3. To test the valve, draw a vacuum at the air suction valve diaphragm and listen for a bubbling sound at the air suction port. If no sound is heard, the air suction valve or diaphragm is faulty.

An intermittent may be caused by any of the following conditions: Thoroughly check any circuitry that is suspected of causing the intermittent complaint. Refer to Intermittents and Poor Connections Diagnosis in Wiring Systems. If a repair is necessary, refer to Wiring Repairs or Connector Repairs in Wiring Systems. Test Description The number(s) below refer to the step number(s) on the diagnostic table. 2. This test checks if communication can be established between the scan tool and the VTD. If the scan tool cannot communicate with the VTD, refer to Diagnostic System Check – Theft Deterrent in Theft Deterrent. 3. This test checks for any opens in the serial data circuit between the VCM and the VTD. This also checks for any intermittent malfunctions associated with the serial data circuit. 4. This step is to determine if the condition that set the DTC is still present. The engine must be cranked in order to set this DTC. If the condition is present, the engine will start and then stall, indicating the VCM is disabling fuel. 7. Use a scan tool to clear and check for any DTCs in all the modules connected to the Class 2 Serial Data circuit (VCM, VTD, ATC, and BCM). the module itself. After repairing the cause of DTC P1626, clear all DTCs from the systems capable of storing this DTC and DTC U1192. 1 Important: Before clearing the DTCs, use the scan tool Capture Info to save the Freeze Frame and Failure Records for reference. The control module’s data is deleted once the Clear Info function is used. Did you perform the Powertrain On-Board Diagnostic (OBD) System Check? — Go to Step 2 Go to Powertrain On Board Diagnostic (OBD) System Check 2 1. Install the scan tool. 2. Turn ON the ignition leaving the engine OFF. 3. Attempt to establish communications with the VTD (Passlock) Control Module. Does the scan tool communicate with the VTD (Passlock) Control Module? — Go to Step 3 Go to Diagnostic System Check – Theft Deterrent in Theft Deterrent 3 Check the Class 2 Serial Data circuit for the following intermittent conditions: Did you find a problem? • An open in the Class 2 Serial Data circuit between the VCM and the VTD (Passlock) Control Module. • A short to ground. • A short to voltage. • Loose or damaged terminals at the DLC, VCM or the VTD (Passlock) Control Module. — Go to Step 6 Go to Step 4 4 1. Turn OFF the ignition. 2. Connect or install any connectors or components that were disconnected or removed. 3. Clear all DTCs using a scan tool. 4. Turn OFF the ignition for 15 seconds. 5. Attempt to start the engine. Does DTC P1626 reset? — Go to Diagnostic System Check – Theft Deterrent in Theft Deterrent Go to Step 5 5 This DTC is intermittent. Are any additional DTCs stored? — Go to the applicable DTC table Go to Diagnostic Aids 6 Repair the circuit as necessary. Refer to Wiring Repairs or Connector Repairs in Wiring Systems.
