Engine Compression Inspection (1.5L Engine): Inspection

NOTE: 

• A Pending or Confirmed DTC may be set during this procedure. Check for DTCs, and clear them as needed.
• After this inspection, you must reset the PCM . Otherwise, the PCM will continue to stop the injectors from operating.

1. Engine - Warm Up

   1. Start the engine. Hold the engine speed at 3, 000 rpm with no load (M/T in neutral, CVT in P or N) until the cooling fan comes on, then let it idle.

2. HDS - Connect 
3. All INJECTORS STOP - Select

   1. Select ALL INJECTORS STOP in the PGM-FI INSPECTION menu with the HDS.

   1. Attach a compression gauge to the spark plug hole. 2. Step on the accelerator pedal to open the throttle fully, then crank the engine with the starter motor, and measure the compression. 3. Measure the compression on the remaining cylinders. 4. If the compression is not within specifications, perform a cylinder leak down test to determine the problem area. Then check the following items, and remeasure the compression: Incorrect valve clearance  Confirmation of camshaft timing  Damaged or worn cam lobes  Damaged or worn valves and seats Damaged cylinder head gasket Damaged or worn piston rings Damaged or worn piston and cylinder bore  5. Turn the vehicle to the OFF (LOCK) mode, then remove the compression gauge from the spark plug hole.

   Maximum Variation:

   Within 200 kPa (2.04 kgf/cm 2, 29.0 psi)

   Compression Pressure:

   Above 980 kPa (9.99 kgf/cm 2, 142.1 psi)

6. Ignition Coil and Spark Plug - Install
7. All INJECTORS STOP - Cancel

   1. Select PCM reset in the PGM-FI Mode menu to cancel ALL INJECTORS STOP with the HDS .
