Description
The 1.6L & 1.8L in-line four cylinder engines have the following features:
•Dual overhead camshafts
• Four valves per cylinder
• Aluminum cylinder head
• Cast iron cylinder block (1.8L Engine)
• Aluminum cylinder block (1.6L Engine)
Operation
The 1.6L & 1.8L engines utilize 4 valve-per-cylinder and a dual overhead camshaft design. The engines use an indi-
vidual coil ignition system. The 1.6L engine uses an aluminum cylinder block, and the 1.8L engine is made of cast
iron. The bearing caps are integrated into the lower cylinder block assembly. An aluminum oil pan bolts to the bottom
of the lower cylinder block. The camshafts are mounted in the cylinder head and act against valve tappets to open
and close the valves. The camshafts are driven off the front of the cylinder head by one timing belt. The belt is driven
by a sprocket that is located on the crankshaft. The piston assembly is an aluminum piston with a cast iron con-
necting rod.
The aluminum cylinder head contains dual overhead camshafts with 4 valve-per-cylinder construction. The valves are
arranged in two in-line banks. The cylinder head incorporates powdered metal valve guides and seats. The cylinder
head is sealed to the block using a multi-layer steel head gasket and retaining bolts.

Description
The 2.4L in-line four cylinder engine has the following features:
•Single overhead camshaft
• Four valves per chamber cylinder head design
• Aluminum cylinder head
• Cast iron cylinder block
Operation
The 2.4L engine utilizes 4 valves-per-cylinder and a single-overhead-camshaft design. The engine uses an individual
coil ignition system and multi-point sequential injection. The cylinder block is made of cast iron and the bearing caps
are integrated into the lower cylinder block assembly. A cast iron oil pan is located at the bottom of the lower cylinder
block. The camshaft is mounted in the cylinder head and acts against the valve tappets to open and close the valves.
The camshaft is driven off the front of the cylinder head by the timing belt. The belt is driven by a sprocket that is
located on the crankshaft. The piston assembly is an aluminum piston with a cast iron connecting rod.
The aluminum cylinder head contains a single overhead camshaft with 4 valves-per-cylinder construction. The valves
are arranged in two in-line banks. The cylinder head incorporates powdered metal valve guides and seats. The cyl-
inder head is sealed to the block using a multi-layer steel head gasket and retaining bolts.

General Troubleshooting Checks
•Confirm the engine trouble light is working properly.
• Confirm that there are no DTCs recorded with the X-431 Scan Tool.
• Confirm that the customer’s complaint is current, and the conditions that are causing the failure are present.
Visual Inspection
•Check the fuel system for any fuel leakage.
• Check the vacuum system for any broken, kinked or incorrectly linked vacuum pipes or hoses.
• Check the intake air pipe for being jammed, leaking, or damaged.
• Check the ignition system for any broken or aging spark plug wires and verify the engine firing order is correct.
• Check the engine ground cable and verify a clean and tight connection.
• Check the sensors and actuators electrical connectors and verify good contact and tight connection.
NOTE :
Repair any of the above conditions first before continuing with symptom diagnostics.
Diagnostic Help
• Confirm there are no current engine DTCs.
• Confirm that the failure exists and the customer complaint can be verified.
• Inspect the engine following the above steps and verify all engine features are operating properly.
• While servicing the vehicle, verify the service record, vehicle maintenance, engine compression pressures,
mechanical ignition timing and fuel conditions.
• If replacing the Engine Control Module (ECM), carry out the validation test. If the failure no longer exists, the
failure is in the ECM; if the failure still exists, reinstall the original ECM and repeat the diagnostic test.
Symptom Diagnostic Test List

• Perform the following to test the secondary ignition system:
Disconnect the injector fuse.
Remove any of the 4 spark plugs.
Connect the spark plug to spark plug wire.
Ground the spark plug on the cylinder block.
Crank the engine to test the secondary ignition system with the spark plugs removed.
Is a strong blue spark visible at each spark plug while cranking the engine?
Ye s>>Go to the next step.
No
>>Check Camshaft Position (CMP) sensor signal at ECM.
If CMP sensor is OK, check the following:
Crankshaft Position (CKP) sensor malfunction
Spark plug wires
Spark plugs
5.CHECK INTAKE AIR SYSTEM
• Check for MAP/MAF sensor.
Is there any contamination?
Ye s>>Clean or replace the sensor.
No
>>Go to the next step.
6.CHECK EXHAUST SYSTEM
• Check the exhaust system for restrictions.
Is there a restriction in the exhaust system?
Ye s>>Repair as necessary.
No
>>Go to the next step.
7.CHECK BASE ENGINE CONCERNS
• Check for base engine concerns (such as improper compression, worn camshaft/valve train, gasket leaks).
Is a fault indicated?
Ye s>>Repair as necessary.
No
>>Go to the next step.
