Car went into limp mode the other day due to the throttle position sensor comming loose anyway after putting it back on and tightening it up the car would not go over 1bar of boost

After messing about with the amal valve i herd a clicking noise comming from it when the cars running anyone had this before?

had another amal valve and a brand new one on it and its still fcuked had to just disconect it for the moment to stop the click/buzzing noise

Anyone?

 

the amal valves do click when they engage/disengage etc.

if all you had wrong was the thorttle position switch then why are you trying to alter the amal valve?

have you tightened up the throttle pos switch at the right point/angle, and do you run a pectel monitor?
or even a secs monitor coming to think of it!?

 

cant help on this ben.
but can soomeone answer what limp home mode is?and do saffs have them?

 

The same/correct TPS was refitted,
Ben hasn't got a ECU monitor, so i fitted it by feel, so should be with in 3 degrees accurate, which should not affect the boost controll.

But if you want Ben, i can volt check it, to get 100% reading. and make sure its reading 100% accuaretly


Basically the ecu is not sending any signal to the amal valves when boosting,
but when it feels like it, is does it on idle.

Its was clicking 10 clicks per second continuously like a machinegun under the bonnet or a bomb waiting to go Bang lol

wasn’t trying to alter the Amal Valve either, i did say above that after it was in limp mode once the problem was found and rectified I.E. the throttle position the car would not boost over 1 bar

As Dan said the throttle position has been set up manual and no i don’t have a pectel or secs monitor

 

Limp Mode is what the ECU puts the car in when it senses that there is a problem like when a sensor is down, it keeps you from revving or bootsing so you cant melt the engine but can still get home

Im sure someone a little more techy can explain it a bit better but that was my experience

 

what will that tell you Dan?

 

Its not like i can just pop up to Birmingham so he can have a look at it i dont think he will be able to diagnose falts on the phone i mean i know hes good im sure he will see this post anyway

 

Means the tps can be set up to 0-1% when throttle shut, and make sure its reading correctly thro out the throttle positions.

 

As it didn't have an AMAL valve fitted, it may be that the chip has been designed not to run one, so when connected it is going loopy .

Just set it up as you have with 1.5 bar and forget about it, as on Monday it will be sorted for good anyway .
