Remove the radiator cap, wet its seal with engine
coolant, then install it on the pressure tester.
Apply a pressure of 93 - 123 kPa (0.95 - 1.25 kgflcm',
14 - 18 psi).
Check for a drop in pressure.
lf the pressure drops, repiace the cap.

1.Wait until the engine is cool, then carefully remove
the radiator cap and fill the radiator with engine
coolant to the top oI the filler neck.
Attach the pressure tester to the radiator, and apply
a pressure of 93 - 123 kPa (0.95 - 1,25 kgf/cm', 14 -
18 psi).
Inspect for engine coolant leaks and a drop in pres-
sure.
Remove the tester, and reinstall the radiator cap.
Check for engine oil in the coolant and/or coolant in
the engine oil.

Descriotion
Misfire detection is accomplished by monitoring the crankshaft speed with the crankshaft speed fluctuation (cKF) sensorwhich is attached to the crankshaft.lfmisfiring strong enough to damage the catalyst is detected, the MIL will blink during the time of its occurrence, and DTcP0300*', P1300*1 and some of DTCs P03ol through P0304 will be stored. Then, after misfire has ceased, the MtL will comeon,
lf misfiring that increases emissions is detected during two consecutive driving cycles, the MIL will come on, and DTcand some of DTCS p0301 through p0304 wi

be stored.NOTE: lf some of the DTCS listed below are stored at the same time as a misfire DTc, troubleshoot those DTcs first. thentroubleshoot the misfire DTC.
