CAUTION: The maximum amount by which the engine management system will adjust the camshaft timing (VCT control unit) is limited to 2 degrees. As a result of this an extremely high degree of accuracy is required for any work which affects the valve timing.

NOTE: If DTC P1519 is stored at same time as DTC P0505, troubleshoot DTC P1519 first, then recheck for DTC P0505. 1. Start the engine. Hold the engine at 3,000 rpm with no load (in Park or neutral) until the radiator fan comes on. 2. Check the engine speed at idle with no-load conditions: headlights, blower fan, rear window defogger, radiator fan, and air conditioner off. Is the engine running at 730+/-50 rpm? YES – Intermittent failure, system is OK at this time.? NO – If the idle speed is less than 680 rpm, go to step 3; if it’s 780 rpm or higher, go to step 4. 3. Disconnect the idle air control (IAC) valve 3P connector. Does the engine speed increase or fluctuate? YES – Adjust the idle speed. If the idle will not adjust properly, clean the passage in the throttle body, and then adjust the idle.? NO – Replace the IAC valve.? 4. Turn the ignition switch OFF. 5. Remove the intake air duct from the throttle body. 6. Start the engine and let it idle. 7. Put your finger on the lower port (A) in the throttle body. Does the engine speed drop below 780 rpm? YES – Adjust the idle speed. If the idle will not adjust properly, replace the IAC valve, and then adjust the idle.? NO – With the throttle valve completely closed, check for vacuum leaks, and repair as necessary.?

Customer Concern: Tests/Procedures: Potential Causes: Tech Tips: Just did a tune up and cleaned the throttle body and now the idle is hunting up and down. 1. Perform the Accelerator Pedal Released Position Learning procedure. 2. Perform the Throttle Valve Closed Position Learning procedure. 3. Perform the Idle Air Volume Learning procedure described in the Identifix article listed for this vehicle. It may be necessary to follow TSB# NTB05-067 and disconnect one or more fuel injectors as necessary to bring the RPM down and then perform the Idle Air Volume Learning procedure. 4. If the idle will not relearn, it may be necessary to bring the vehicle to the dealer to have the factory scan tool, try going through the relearn procedures. 5. If the problem still occurs, the vehicle may require throttle body replacement. Idle Relearn Procedure Engine speed at 200 RPM or more over the target idle speed will set this code. There is a TSB (TSB# NTB05-067) concerning this code that refers to disconnecting one or more fuel injectors to bring the RPM down and perform the Idle Air Volume Learning procedure. It often takes disconnecting two injectors to bring the engine RPM low enough for the idle relearn to work. The idle will not relearn if the engine speed is too high. During the relearn procedure, idle relearning actually begins when the engine is started. The TSB refers to using the factory Consult scan tool, but the manual procedure does work if the procedure is followed EXACTLY. The engine and automatic transmission (if equipped) needs to be warmed up too – follow the preparation instructions.
