P0019 Crankshaft Position - Camshaft Position Correlation (Bank 2 Sensor B)

DESCRIPTION

DTC No. DTC Detection Condition Trouble Area
P0017

With engine warmed up and idling, valve timing on bank 1 exhaust side deviates for 1 minute or more

(2 trip detection logic)

  • Valve timing

  • Oil control valve for exhaust side (bank 1)

  • Camshaft timing exhaust gear assembly (bank 1)
P0019

With engine warmed up and idling, valve timing on bank 2 exhaust side deviates for 1 minute or more

(2 trip detection logic)

  • Valve timing

  • Oil control valve for exhaust side (bank 2)

  • Camshaft timing exhaust gear assembly (bank 2)

MONITOR DESCRIPTION

These DTCs are output when a valve timing deviation condition is detected. While the vehicle is being driven or the engine is idling (after the battery terminals are reconnected), if a valve timing deviation is detected during the valve timing initialization operation, it is determined that a malfunction has occurred. If this condition is detected while driving, a DTC is output (2 trip detection logic). However, if the valve timing deviates, the camshaft position sensor malfunction DTC P1340 may be output.

A DTC is output if the following occurs: 1) the engine is idled, and then the engine switch is turned off; and 2) the engine is started and the engine is idled.

INSPECTION PROCEDURE

Tech Tips

Read freeze frame data using the intelligent tester. Freeze frame data records the engine condition when malfunctions are detected. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air-fuel ratio was lean or rich, and other data from the time the malfunction occurred.

PROCEDURE


  1. PERFORM ACTIVE TEST USING INTELLIGENT TESTER (VVT EX B1 OR VVT EX B2)

    Tech Tips

    If the VVT system can be operated through the Active Test, it can be determined that there is no problem in the VVT system.


    1. Connect the intelligent tester to the DLC3.

    2. Turn the engine switch on (IG) and turn the tester ON.

    3. Start the engine and warm it up.

    4. Engine is idling.

    5. Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank1) or Control the VVT Exhaust Linear (Bank2).

    6. Check the engine speed while operating the Oil Control Valve (OCV) using the tester.

      OK
      VVT EX B1 or VVT EX B2 Engine Condition
      0% Normal engine speed
      30% Engine idles roughly

  2. ADJUST VALVE TIMING

    A01GMQ5E01

    1. Remove the cylinder head cover bank 1 and bank 2.

    2. Turn the crankshaft pulley, and align its groove with the timing mark "0" of the timing chain cover.

    3. Rotate the crankshaft pulley and align its notch to timing mark 0 of the timing chain cover. Check that the timing marks of the camshaft timing gears and camshaft timing exhaust gears are at the positions shown in the illustration.

      OK
      Timing marks on camshaft timing gears are aligned as shown in the illustration.

    4. Reinstall the cylinder head cover.

  3. INSPECT CAMSHAFT TIMING OIL CONTROL VALVE


    1. A01GNVWE17

      Remove the OCV Click here.

    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance
      Tester Condition Condition Specified Connection
      1 - 2 20°C (68°F) 6.9 to 7.9 Ω

    3. Apply the positive battery voltage to terminal 1 and negative battery voltage to terminal 2. Check the valve operation.

      OK
      Valve moves quickly.

  5. CONFIRM WHETHER MALFUNCTION HAS BEEN SUCCESSFULLY REPAIRED


    1. To initialize the ECM's valve timing, disconnect the cable from the negative (-) battery terminal for 1 minute.

    2. Connect the cable to the negative (-) battery terminal Click here.

    3. Connect the intelligent tester to the DLC3.

    4. Start the engine and idle it for 5 minutes.

    5. Enter the following menus: Powertrain / Engine / DTC.

    6. Read the DTCs.
