Inspection Procedure

WARNING: This page is about a different variant/trim than selected.

Inspect whether to leak air or stuck
1. Inspect a contamination, gasket and installation
  - Damaged or installation of throttle body
  - Damaged or installation of intake manifold and gasket which is installed in surge tank
  - Contamination and stuck in intake manifold
  - Contamination between surge tank and PCSV and stuck open
  - Damaged or contamination of HO2S (up)
  - Visual check leak a catalyst and a exhaust system of HO2S (down)
Inspection sensor
1. Check an installation of HO2S, connector connection, damaged wire and PCM.
2. Check a HO2S silicon contamination that check whether it is to dredge the sensor with white flour. Also, an data would be abnormal.
3. Check a HO2S contamination (Flowing in fuel, coolant or engine oil)
4. Check a intake air flow sensor contamination or poor performance, connection and wiring.
5. Start an engine and check that both throttle position sensor and pedal sensor data would be increased.
6. Check a PCM ground.
Inspection of fuel line
1. Check whether a fuel filler would be stuck or not.
2. Check a fuel level.
3. Check whether leak a low pressure fuel or it is stuck.
4. Measure a fuel pressure in idle after installing a fuel pressure measurement gauge.
  - Specification : Fuel Pressure: 480 to 520 kPa (4.9 to 5.3kgf/cm² , 69.6 to 75.4 psi)
Inspection of injector
1. Measure a resistance injector
  - MPI injector specification : Approx. 11.4 to 12.6Ω (20°C)
  - GDI injector specification : Approx. 1.4 to 1.7Ω (20°C)
Inspection of engine pressure
1. Engine coolant temperature could be became between 80 and 95°C (176°F and 203°F) after starting an engine and stop.
2. Disconnect an injector extension connector and an ignition coil connector.
3. Disconnect an ignition coil and an ignition plug.
4. Install a pressure gauge to ignition plug hole.
5. A throttle valve is full opened.
6. Measure a pressure after cranking at least 20 times.
  - Normal Value
  - Specification : 13.0kgf/cm² (200 to 250 rpm)
  - Limitation : 11.5kgf/cm²
  - Deviation each one cylinder pressure : Below 1.0kg/cm²
Good
- Check for engine coolant loss. If there is a large loss of coolant, check the condition of the engine block, cylinder head or cylinder head gasket for damage.
- Repair or replace as necessary and then, go to "VERIFICATION OF REPAIR " procedure.
No Good
- Repair or replace as necessary and then, go to "VERIFICATION OF REPAIR " procedure.
