•A cylinder head gasket leak can be located between adjacent cylinders, between a cylinder and the adjacent
water jacket or from an oil passage to the exterior of the engine.
• Possible indications of the cylinder head gasket leaking between adjacent cylinders are:
Loss of engine power
Engine misfiring
Poor fuel economy
• Possible indications of the cylinder head gasket leaking between a cylinder and an adjacent water jacket are:
Engine overheating
Loss of coolant
Excessive steam (white smoke) emitting from exhaust
Coolant foaming
Engine Oil Pressure Test
1. Check the engine oil level.
2. Disconnect the oil pressure switch electrical connector.
3. Remove the oil pressure switch.
4. Install the mechanical oil pressure gauge.
5. Start the engine and warm to normal operating temperature.
6. After the engine has been warmed up, check that the oil pressure is within the specifications. Standard Oil Pressure: At 750 ± 50 RPM: 0.8 MPa
7. Stop the engine.
8. Remove the oil pressure gauge.
9. Apply the specified sealant to the thread (1) of oil pressure switch.
10. Install the oil pressure switch (Tighten: Oil pres- sure switch to 10 ± 2 N·m).

Oil Filter
Removal & Installation
NOTE :
The following special tools are required to perform the repair procedure:
• MB-991828 - Oil Filter Wrench
• MB-991396 - Oil Filter Wrench
WARNING!
Prolonged and repeated contact with engine oil will harm your skin. If engine oil is spilled on your skin, wash it
off immediately with water. In addition, used engine oil contains potentially harmful contaminants which may
cause skin cancer. Always use adequate skin protection when performing vehicle service.
CAUTION:
When servicing the oil filter, install the special tool against the base of the filter to avoid deforming
the filter.
1. Start the engine and allow it to warm up to normal operating temperature.
2. Stop the engine and remove the engine oil filler cap.
3. Raise and support the vehicle.
4. Remove the oil pan drain plug and drain the oil out of the engine.
WARNING!
The engine oil is hot and can burn your skin.
5. Remove the under cover.

EPC Lamp Control Strategy
The Electronic Pedal Control (EPC) lamp will be on for a few seconds and turn off after the ignition switch is turned
on and the engine is not running. After the engine started, the EPC lamp will go off if the DTC is not existent in ECM.
If the internal self-check failed, the EPC lamp will continue to light.
Electronic Throttle Control Actuator Self-Learning Condition
•Engine stopped and the ignition switch on.
• Vehicle speed is 0 km/h.
• The Engine Coolant Temperature (ECT) is between 5.25°C and 100.5°C.
• The intake air temperature is more than 5.25°C.
• The accelerator pedal fully released.
• Battery voltage is more than 12 V.
Electronic Throttle Control Actuator Self-Learning Operating Procedure
Turn the ignition switch on for 10 seconds, then turn the ignition switch off. During the procedure, do not operate any
other components.
Self-Learning Components
Perform the self-learning process when the following repairs have been made:
•Replaced the ECM
• ECM which was disconnected and reconnected
• Replaced the Accelerator Pedal
• Replaced the Electronic Throttle Control Actuator
Self-Learning Operating Procedure
Turn the ignition switch on for 10 seconds, then turn the ignition switch off. During the procedure, do not operate any
other components.
Self-Learning Condition
The self-learning condition as the Electronic Throttle Control Actuator Self-Learning Condition.
CAUTION:
Ensure that the Electronic Throttle Control Actuator self-learning process lasts for at least 10 sec-
onds according to the Electronic Throttle Control Actuator self-learning condition. If the self-learn-
ing process fails, the engine can’t be started or the EPC lamp will be on. If this condition occurs,
perform the Self-Learning operating again after the DTCs be erased in ECM.

Diagnostic Help
1. Confirm that the malfunction is current and carry-out the diagnostic tests and repair procedures.
2. If the Diagnostic Trouble Code (DTC) cannot be deleted, it is a current fault.
3. Use a digital multimeter to perform voltage readings on the Electronic Fuel Injection (EFI) system.
4. Program the vehicle Immobilizer control module whenever the Engine Control Module (ECM) is replaced.
5. The scan tool connects to the Data Link Connector (DLC) and communicates with the ECM.
6. If the failure is intermittent perform the following:•Check for loose connectors.
• Look for any chafed, pierced, pinched, or partially broken wires.
• Monitor the scan tool data relative to this circuit and wiggle test the wiring and connectors.
• Look for the data to change or for the DTC to reset during the wiggle test.
• Look for broken, bent, pushed out or corroded terminals.
• Inspect the sensor and mounting area for any condition that would result in an incorrect signal, such as
damage or foreign material.
7. Remove the ECM from the troubled vehicle and install in a new vehicle and test. If the DTC can not be deleted, the ECM is malfunctioning. If the DTC can be deleted, return the ECM to the original vehicle.
Ground Inspection
Ground connections are very important to the proper operation of electrical and electronic circuits. Ground connec-
tions are often exposed to moisture, dirt and other corrosive elements. The corrosion (rust) can become an unwanted
resistance. This added resistance can alter the way a circuit works.
Electronically controlled circuits are very sensitive to proper grounding. A loose or corroded ground can drastically
affect an electronically controlled circuit. A poor or corroded ground can effect the circuit. Perform the following when
inspecting a ground connection:
1. Remove the ground bolt or screw.
2. Inspect all mating surface for tarnish, dirt, rust, etc.
3. Clean as required to assure good contact.
4. Reinstall bolt or screw securely.
5. Inspect for add-onaccessories which may be interfering with the ground circuit.
6. If several wires are crimped into one ground eyelet terminal, check for proper crimps. Make sure all of the wires are clean, securely fastened and providing a good ground path. If multiple wires are crimped to one eyelet, make
sure no excess wire insulation has been crimped creating a bad ground.

• The Engine Coolant Temperature (ECT) is between 5.25°C and 100.5°C.
• The intake air temperature is more than 5.25°C.
• The accelerator pedal fully released.
• Battery voltage is more than 12 V.
Electronic Throttle Control Actuator Self-Learning Operating Procedure
Turn the ignition switch on for 10 seconds, then turn the ignition switch off. During the procedure, do not operate any
other components.
