Typical Malfunction Thresholds
WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Lexus UX 250h, 2023 Lexus UX 250h, 2022 Lexus UX 250h, 2021 Lexus UX 250h, and 2020 Lexus UX 250h. However, it is still accessible from the selected car via links, so may be relevant.
P0014: ADVANCED CAMSHAFT TIMING
| Both of the following conditions are met | - |
| Deviation of actual valve timing and target valve timing | More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit |
| Valve timing | No change at advanced valve timing |
P0015: RETARDED CAMSHAFT TIMING
| Both of the following conditions are met | - |
| Deviation of actual valve timing and target valve timing | More than 5°CA (Crankshaft Angle) for 5 seconds or more after the VVT hold duty ratio learned value reaches the upper or lower limit |
| Valve timing | No change at retarded valve timing |
If the difference between the target and actual camshaft timing is greater than the specified value, the ECM operates the VVT actuator for 10 seconds by applying and releasing oil pressure. Then, the ECM monitors the camshaft timing change for 10 seconds.
