Engine Suddenly Loosed Power During Driving .

Sometimes Trouble occurred due to Electrical Circuit or Electrical wires loosed from the terminal pins
as this day that I encounter. On idling the Engine is good even acceleration but in actual driving on high way, suddenly loosed the power.take a trouble code with GDS(Global Diagnostic System)
data trouble code not found.
1) Trouble Condition :

= Engine Suddenly loosed Power During Driving.
2) Trouble Cause:
= Loosed Main Relay Pin of Engine Compartment Fuse box.
3) Diagnosis:

1. Check with GDS to Confirm the trouble code as referral of trouble occurred.
   = CKP(Crankshaft Position Sensor)
   CKP Description
   = Different from the existing cam phase angle type.CVVT is the device w/c varies cam phase angle continuously to be optimum.And w/ engine oil pressure, It operates.
   CVVT consists of OCV and phaser. OCV mounted on cylinder head, controls the amount and direction of oil delivered to cam phaser by oil valve w/c is connected to a solenoid.Cam pheser , rotating cam phaser rotor w pressure and amount of oil produced by OCV , rotates camshaft forcefully for or against the rotating direction and finally, cam phase changes with the appliance of CVVT, engine power, fuel efficiency and quality of exhaust gas are improved.  
   Detecting Condition:
   = Determines if the Cam target is aligned correctly to crank.
   = Real Offset value.
   
2. Check the current data of CKP: Normal Function.
3. So are all possible cause are normal = we will visually check.
4. Check the engine compartment fuse box if there is relay of fuse loosed from its pin.
   = found out that main relay loosed from its pin, So check and retightened the pin. make roadtest still the problem occurred. replace with good relay.
   = the problem automatically solved.

4) Repair Guide:

• Replace main relay.
