Hi,

The missus ST170's engine management light has come on. Its got 'Bluefin' so ive plugged it in to check what the problem is.

It displayed 'DTC P1518'...

Ive looked it up and got the following;

P1518 - Intake Manifold Runner Control Malfunction (Stuck Open) The IMRC system is monitored for failure during continuous, key ON engine OFF or key ON engine running self-test. The test fails when the signal on the monitor pin is less than an expected calibrated range at closed throttle. IMRC monitor signal circuit shorted to PWR GND or SIG RTN
Damaged IMRC actuator
Damaged PCM
An IMRCM PID reading approximately near 1 volt at closed throttle may indicate a fault

Has anybody got any idea how to fix this (preferrably without goin to Ford )

Any help would be great

Cheers.
