Hello guys,
This is a 97 turbo & i have issue with engine light fault code 121 or P1140( both are same)- load detection.
I tried pressure test from the MAF pipe, i had some small vacuum pipe leaking, fixed it, did test drive again but fault returned again.
I did the test again now I can see that during this test if i keep pressurising the system ( not too much pressure), oil drops starts to spill from engine oil cap. Is this normal. Please note that I had closed the pressure relief valve pipe that comes from top of engine oil tank( as suggested by workshop manual )
during drive it never happens, oil does not drops.
this fault 121 occurs at low speed driving after driving the car around 30 minutes. At idle there is no fault.
Please suggest if someone rectified this fault.
Thankyou .
