No mivec

Post by **diver705** » Sat Jul 21, 2012 10:05 pm

Hello people, new to site

just bought a gpx cheap in great condition but has no mivec actuation. Its had a diag with the previous owner and been told the lambda/oxygen sensor has gone. Sound like it would give the complaint ive got. Any info would be great, mechanic by trade but know very little about fto's p.s its auto too.

Could it just be that the oxygen sensor is fried?

Or you bought a GR thinking it's a GPX.

i know it might be simple but, i had a 'no mivec' moment once,? or so it seemed, when my intake wasnt connected properly at the manifold?(i think thats what u call it) was slightly loose

I think you need to try and scan codes out of the ECU, it may point you in the right direction. There are a lot of different reasons that stop MIVEC from kicking in, it's like a safety fallback for the ECU to protect the engine. A lot of guys here lately have had no MIVEC due to a bad alternator.
Is your engine light on?
Is the engine rev limiting at 6000RPM?
If you don't have access to a diagnostic scan tool to suit Mitsubishi (MUTII) you can do a manual scan, here is the link for the how to........http://ftoaustralia.com/v3/viewtopic.ph ... 67&start=0
Good Luck

What is the oil level Like?
If low it will stop you from going into mivec.

No eml light on dash alternator output good, oil level good and clean will check intake pipe 2moz code read only code for heated o2 sensor dieing to sort it out as i bet they good like f*$k when running right. Cheers for info keep you informed.

Ok more info for you guys, o2 sensor flash code has gone, oil level was on min topped up mivec now kicking in hear the sound change on engine also but hesitating and hold back at aprox 7000 rpm think a good service in order.

Yet another win for the low oil

revs not limited to 6000 rpm revs to 8500rpm, alternator output good, disconnect neg terminal on battery with engine running passed test kept running. If mivec solenoid was stuck, malfunctioning would that cause it. Wheres it located people

manual scan done again no flash codes. presume im doing it right.

I don't believe there is a MIVEC solonoid. MIVEC is controlled by the ECU gathering information through most engine/transmission sensors. MIVEC cams are switched on/off via the oil control valves under the rocker covers.

Thanks mate, Just been talking to a Japanese specialist repairer and her recons ive got a coil pack braking down under load, which will not put the engine light on until it totally fails. Sooooo i will resistance check the coils, ht leads and check plugs. Figures crossed.
