The LDP is a diagnostic tool that the ECM uses to monitor fuel tank pressure loss. A loss in
fuel tank vapor pressure will turn the check engine light on. A faulty LDP will also turn the
check engine light on.

What is the exact problem you have? Any stored fault codes?

Often it can be a simple as a faulty fuel cap, check this first.
