After an accidental over reving of the engine, check engine light flashed and then cam on steady. I noticed my car was running hotter than normal, and discovered a loss of coolant. Upon trying to fill the coolant,with engine running, the engine eventally stalled and would not restart. Symptomatic of plugs not firing or not getting fuel to plugs. After sometime, I noticed coolant leaking from air intake (coolant dripping out of air filter and air intake duct). The coolant was dripping directly on a wiring harness connected to some type of electronic modual. I then pulled a sparkplug and notice an excessive amount of oil/grease on the firing portion of the plug. Would like to know what causes coolant to enter air intake, oil/grease on plugs, and what the electrical modual is directly under air filter housing?
Hia I have a Honda accord 2.4 vtec im getting steam coming from my exhaust even when the car is warm what are the symptoms need help urgently and its not going past 5000rpm
Probably blew your intake manifold gasket that would cause the antifreeze to enter the intake also a blown head gasket would cause the same symptoms as to the module I'm not sure could be the computer or the abs pump

Inspect the powertrain control module (PCM) grounds for being clean, tight, and in the proper locations. Refer to Engine Controls Schematics .

Sensor/System
?ā¬Ā¢
Test the engine coolant temperature (ECT) sensor for being shifted in value. Connect a scan tool. Compare the engine coolant temperature against the intake air temperature (IAT) on a cold engine. The ECT and IAT sensor values should be within ?Ā± 3?Ā°C (5?Ā°F) of each other. If the ECT sensor is out of range with the IAT sensor, check the resistance of the ECT sensor. Refer to Temperature Versus Resistance for resistance specifications. Replace the ECT sensor if the resistance is not within the specification. If the sensor is within the specification, repair the ECT signal circuit for high resistance.

Inspect the mass air flow (MAF) sensor installation. A MAF sensor that is incorrectly installed may cause a hard start. Important: The embossed arrows on the MAF sensor indicate the direction of the intake air flow. The arrows must point toward the engine. Install the MAF in the proper direction. Refer to Mass Airflow Sensor/Intake Air Temperature Sensor Replacement .
?ā¬Ā¢
Inspect the camshaft position (CMP) sensor for proper mounting and/or a bad connection. A long crank time occurs if the PCM does not receive a CMP signal.
Fuel System
?ā¬Ā¢
Inspect the fuel pump relay operation. The fuel pump should turn ON for 2 seconds when you turn ON the ignition. Refer to Fuel Pump Electrical Circuit Diagnosis .
?ā¬Ā¢
A faulty in-tank fuel pump check valve allows the fuel in the lines to drain back to the tank after the engine stops. Refer to Fuel System Diagnosis .
?ā¬Ā¢
Inspect both injector fuses for being open. An open injector fuse causes four injectors and four ignition coils not to operate. Replace the fuse. Inspect the injector circuits and the ignition coil circuits for an intermittent short to ground.
?ā¬Ā¢
Inspect for incorrect fuel pressure. Refer to Fuel System Diagnosis .
?ā¬Ā¢
Inspect for a restricted fuel filter. Refer to Fuel System Diagnosis .
?ā¬Ā¢
Inspect for a contaminated fuel condition. Refer to Alcohol/Contaminants-in-Fuel Diagnosis .
Ignition System
?ā¬Ā¢
Test both injector fuses for being open. An open injector fuse causes four ignition coils and four injectors not to operate. Replace the fuse. Inspect the ignition coil circuits and the injector circuits for an intermittent short to ground.

Inspect for proper ignition voltage output with J 26792 Spark Tester. Refer to Electronic Ignition (EI) System Diagnosis .
?ā¬Ā¢
Remove the spark plugs and check for the following:
-
Correct heat range
-
Wet plugs
-
Cracks
-
Wear
-
Improper gap
-
Burned electrodes
-
Heavy deposits
Refer to Spark Plug Inspection in Engine Electrical.
?ā¬Ā¢
Determine the cause of the fouling before replacing the spark plugs if the spark plugs are gas, coolant, or oil fouled. Refer to DTC P0172 or P0175 for diagnosis of the rich condition. Refer to Spark Plug Inspection in Engine Electrical for diagnosis of coolant or oil fouled spark plugs.
?ā¬Ā¢
Inspect for bare or shorted ignition wires.
?ā¬Ā¢
Inspect for loose ignition coil grounds. Refer to Electronic Ignition (EI) System Diagnosis .
