Hello, after bringing the 3door out after its winter hiding I taxed and took it out for a long run yesterday and now have a couple of errors the SECS monitor is picking up.

The first is the Water temp on the monitor fluctuates from 80c to 106c all the time.. New water temp sensor has been ordered..

The second is that on occasion I’m getting the error that the MAP senor is out of range.. I’m getting this when driving normally not even when under boost. Any ideas and should I be concerned..

Cheers

 

Id be gettin a new map sensor aswell buddy to be on the safe side

 

Check map sensor is plugged in correctly, and all the terminals behind the SECS monitor, if this doesn't solve it I can't think of anything else but get a new map sensor

 

Thanks guys, best i get myself on the phone to Stu then eh.. More money

 

Ahh least its semi-cheap matey !!

I have just fitted a brand new clutch and uprated gearbox to my saph cossie 4by , took it for a drive and the t34 turbo is now ill and requires rebuilding

Fookin joys

Lol, still least ma wee diesel escy van doesnt break

 

Now that sounds painfull in the pocket, feeling quite happy about mine now

 

Yep i thought that would have cheered ye up

 

if the battery has been diconnected for a while the monitor may have reset.
it will go back to the settings for a standard map sensor I think which means a 3 bar would show out of range.
worth a try

 

ah thanks for that Ian, I took it to our local meet last night and it behaved itself so will give it another chance..

 

Have you tried going through the settings and selecting 3 Bar Map Sensor instead of 2 bar?

 

Not yet Smisy, I will check that if it comes back with the error.

Thanks for the replys guys

 

thats cheap probs mate, mines going to be crushed soon

 

my SECS monitor does this sometimes when pushed really hard.

Have you wired a direct earth into your 3bar - just in case?

and how do you select 3bar from the SECS monitor?

 

Press both the buttons at the same time and it comes up with the menu options bit

Somewhere in there you can select the map sensor to be 2, 2.5 or 3 bar IIRC

 

Im taking mine to MR Shead next week for a setup so will see what happens when the boost is raised a tad more.. No Ive not run a direct earth Ran, think it could be worth doing..

 

BTW does anyone know how easy it is to replace the water temp sensor, the senor the ECU uses?

 

v easy job although mine was with the engine out so may be a bit more fiddly with it in.

Just unscrew the old one and screw the new one in its near the dipstick tube. I smeared a tiny bit of sealant on the threads too.

I changed the gasket or the plate that it screws into while i did mine.

 

Thanks Andy, I take it the coolant is going to have to be drained?

 

my engine was in bits when i did mine however i dont think it would need to as its higher up than the rad, headertank. So in theroy some water should some out but not too much.

Just remember to check water level and for air in the system when you start her next (just let it idle with the header tank cap off and top up as required)

 

Thanks Job for the weekend me thinks..
