If a Check Engine Light illuminates indicating leak detection pump (LDP) failure, the cause is often pinched or disconnected vacuum lines to the pump. Vacuum lines should be inspected before replacing the leak detection pump. Contamination (carbon or debris) in the pump can cause failure and any hoses should be cleared before a new pump is installed.

There was a recall to replace the vacuum hose for the brake booster. In the presence of oil, the original hose could swell and become disconnected. The brakes would function but power assist would be lost and the pedal would feel very hard.
