How can I check liana fuel pressure without gauge ?
I mean if I dont have gauge then any desi formula to guess that pressure is almost ok .
And 2ndly which is injector control relay there are various relays in bonet fuse/relay box ?

you will need to make a fuel line adapter with a guage in between to check fuel pressure. There is no other way and if you want to guess fuel pressure. Go to "totay ki faal" wala and ask the "tota" for fuel pressure. His answer will be A spec.

That's interesting but their came a new question:

How the cam sensor can bring out the status of each valve on the line to ecu. Or the ecu compares the cam pisition with a fixed algo to determine the valve condition.

The cam rotates at half crank speed and the cam itself has multiple teeth to excite the magnet of the cam sensor which the ECU sees as "event" e.g. crank TDC+plus cam top = engine cylinder position 1 compression - similarly crank TDC + cam bottom = cylinder 3 (etc etc), the ignition and fuelling events are also timed accordingly.

When the VVT works the cam signal will show up before the crank gets to TDC (this is the feedback and confirmation for ecu that the VVT worked in advance mode), ECU will keep on commanding the oil control valve in either advance or retard position which in turn sends oil to the advance or retard channels of the actuator on the cam.

where actuator is located on engine Assy

VVT actuator and variator are the same thing - its the round assembly on the intake camshaft (cherry blossom ki dibbi) - it gets turned by timing chain.

Xulficar bhai plz tell any software setting that reduce the petrol consumption of liana. I mean to ask does ecu of some cars allow us to up/down petrol settings of that car .
Or petrol is fix matter only ecu itself manage this ?

no such software exists, the ECU will adjust fuelling and timing to keep the engine running at peak performance and even compensates for wear.

This is how a vvt actulator looks like

is this vvt solenoid ??

Hahaha ! Thank for suggestion of totay ke fall .

How can we know if our clutch wire is ok or bad? Is there a cable or what?

AOA to all members,
does any one know where is Liana radio antenna is located?
Thanks

It is printed on the top portion of rear wind shield.

it is oil pressure gauge .

Hydraulic clutch no clutch cable in liana

[abid110]

Hydraulic clutch no clutch cable in liana

Matlab it is maintenance free? So the clutch is not connected thru a wire/cable so no chances of cable breaking (like my accelerator cable)?

where is vvt solenoid ?

[gullahmad]

I changed the swift injectors to liana but face smoke issue and reduced pick up. Parameters for both cars r same like fuel pump pressure and injector capacity and power . Only difference is no of holes , i.ie 4 & 12 holes.
Waiting for opinions.
As enthusiastic & hobbiest of automobiles I do some experiments on my cars.

Maintenance free nope you need to change clutch oil every year

How is it drained?

you see that big lump on the side of the tappet cover and the upper part of the timing chain cover... The reason its a big lump is because it houses the VVT actuator for the camshaft.
