Toyota Yaris: Sfi System / Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A (P001600,P001700)

Toyota Yaris XP210 (2020-2022) Reapir and Service Manual / Engine & Hybrid System / G16e-gts (engine Control) / Sfi System / Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor A (P001600,P001700)

DESCRIPTION

In the VVT (Variable Valve Timing) system, the appropriate intake and exhaust valve open and close timing is controlled by the ECM. The ECM performs intake and exhaust valve control by performing the following: 1) controlling the camshaft, cam timing oil control solenoid assembly, camshaft timing gear bolt (camshaft timing oil control valve) and operating the camshaft timing gear; and 2) changing the relative positions of the camshaft and crankshaft.

DTC No.

Crankshaft Position - Camshaft Position Correlation Bank 1 Sensor B

Deviation in the crankshaft position sensor signal and camshaft position sensor (for exhaust camshaft) signal (2 trip detection logic).

  • Valve timing
  • Cam timing oil control solenoid assembly (for exhaust camshaft)
  • Camshaft timing gear bolt (exhaust camshaft timing oil control valve)
  • Camshaft timing exhaust gear assembly
  • ECM

SAE: P0017

MONITOR DESCRIPTION

To monitor the correlation of the intake camshaft position and crankshaft position, the ECM checks the VVT learned value while the engine is idling. The VVT learned value is calibrated based on the camshaft position and crankshaft position. The intake valve timing is set to the neutral position while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM illuminates the MIL and stores DTC P001600.

To monitor the correlation of the exhaust camshaft position and crankshaft position, the ECM checks the VVT learned value while the engine is idling. The VVT learned value is calibrated based on the camshaft position and crankshaft position. The exhaust valve timing is set to the most advanced angle while the engine is idling. If the VVT learned value is out of the specified range in consecutive driving cycles, the ECM illuminates the MIL and stores DTC P001700.

  17. Enter the following menus: Powertrain / Engine / Trouble Codes [G].
  18. Read the pending DTCs.

    HINT:

    • If a pending DTC is output, the system is malfunctioning.

  19. Check the DTC judgment result.

    HINT:

CAUTION / NOTICE / HINT

HINT:

  • The monitor for this DTC detects when the timing chain is shifted by two teeth or more.
  • Read freeze frame data using the GTS. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. 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.

    Break-In Period

    No special break-in is necessary, but a few precautions in the first 600 miles (1,000 km) may add to the performance, economy, and life of the vehicle.

    Do not race the engine. Do not maintain one constant speed, either slow or fast, for a long period of time. Do not drive constantly at full-throttle or high engine rpm for extended periods of time. Avoid unnecessary hard stops. Avoid full-throttle starts.
