Ask an Expert..... » truck goes into limp mode

Hi all,

Having yet more trouble with my l200 2.5DID. I have an engine management light on and the code reads P0089, I've done the suction control valve... any other suggestions? It goes into limp mode when I leave it idle for a few moments.

Thanks any help appreciated

No sorry, but you could try this
New fuel filter (Gen Mitzi) and a can of Forte Advanced derv treatment in the fuel.
Give it a good run at 70mph for half an hr,

I just done a random google search and apparently two people had the same fault code & posters this information.........

it is P0089 CODE IS FUEL PRESSURE REGULATOR 1 PERFORMANCE.CODE 642 SENSOR REFERENCE VOLTAGE CIRCUIT "A" LOW.AND CODE 2004 IS INTAKE MANIFOLD RUNNER CONTROL STUCK OPEN.CK FOR BAD OR MISSING VACUUM LINES

Here's the link I copy & pasted it from:-
Hope it's of some use??
