- If DTC P0014 or P0015 is displayed, check the exhaust camshaft circuit for the right bank VVT system (bank 1).
- Bank 1 refers to the bank that includes cylinder No. 1.
- If DTC P0024 or P0025 is displayed, check the exhaust camshaft circuit for the left bank VVT system (bank 2).
- Bank 2 refers to the bank that does not include cylinder No. 1.
- Read freeze frame data using the Techstream. 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.
PROCEDURE
1. CHECK ANY OTHER DTCS OUTPUT (IN ADDITION TO DTC P0014, P0015, P0024 OR P0025)
(a) Connect the Techstream to the DLC3.
(b) Turn the engine switch on (IG).
(c) Turn the Techstream on.
(d) Enter the following menus: Powertrain / Engine / Trouble Codes.
(e) Read the DTCs.
Result:
HINT
If any DTCs other than P0014, P0015, P0024 or P0025 are output, troubleshoot those DTCs first.
B -- GO TO DTC CHART See: Diagnostic Trouble Code Descriptions/SFI System
A -- Continue to next step.
2. PERFORM ACTIVE TEST USING TECHSTREAM (CONTROL THE VVT EXHAUST LINEAR (BANK 1 OR 2))
(a) Connect the Techstream to the DLC3.
(b) Start the engine.
(c) Turn the Techstream on.
(d) Warm up the engine.
(e) Enter the following menus: Powertrain / Engine / Active Test / Control the VVT Exhaust Linear (Bank 1) or Control the VVT Exhaust
Linear (Bank 2).
(f) Check the engine speed while operating the camshaft timing oil control valve assembly using the Techstream.
OK:
NG -- CHECK VALVE TIMING (CHECK FOR LOOSE OR JUMPED TEETH ON TIMING CHAIN)
OK -- Continue to next step.
3. CHECK WHETHER DTC OUTPUT RECURS (DTC P0014, P0015, P0024 OR P0025)
(a) Connect the Techstream to the DLC3.
