After work intended to address an oil-pressure warning that appears at hot idle, repeat the original conditions in a safe place and check whether the symptom returns. Record engine temperature, idle speed, and whether the warning disappears when the engine is switched off. Record the result before clearing codes or resetting adaptations.
Follow the maker’s procedure for drive cycles and readiness monitors. Check the oil level only when safe and as the manual specifies; do not rely on a pressure switch guess. If the issue remains, return to the evidence instead of swapping another part.
