Car not climbing steep hill

[zak82]

A gear icon with exclamation mark inside of amber color appears after gear shifts from 2nd to 3rd. There's no noticeable difference in upshift or downshift. The sign remains there till switch off. Code tells its P0717, input shaft sensor

Is there anything to do with non-availability of drive shaft as its AWD ?

Is it the torque converter which is faulty?

And one more point, this problem didn't arise just yet, its there since I bought it.

I would like to know possible causes of this issue . What are the possible symptoms of this problem which I might not be noticing but its there?

Solution is appreciated plz

Increase the boost of your turbo. Install a higger one. It will spool at higher RPM but increase HP.

Or get a bigger car.

When that happens, one or both tires may be slipping. If so, your problem may be one of traction rather than power.

his car is AWD coupled with 660 cc , hence wheel spin uphill is next to impossible, no?

If the AWD system is working, which it cannot if the rear shaft has been removed.

You need to ascertain if the wheels are spinning or not while you try to accelerate up a hill; if they are then surely your problem has nothing to do with the engine or transmission. When you're on an inclined surface and going upwards; the vehicle's weight shifts towards the rear thus lessening traction on the front wheels. In lightweight FWD cars this may result in a lot of wheel spin. Try removing rear seat passengers - that may help.

Wheels r not spinning. If they were,there was no issue ..

isolate the wiring and test the sensor, most probably would be a hall effect sensor with a pull down signal, Test the wiring for supply and ground then test the signal wave form - get a scope on it - a good repair shop would have it, repair or replace as necessary.

I've gone for an easier solution but didn't help. Replaced the sensor with brand new one from Japan. I didn't want the transmission to open for diagnosis bcoz it wud take some effort.
The only variable remain now is the transmission which in my point of view needs to be checked for this prob

The sensor should be external on the case - at worst it would be in the valve body and not a problem to remove, testing is done at wiring level, trace the wires and go from there - As I said a good service technician can test any hall effect sensor easily. Best tested with a scope - you need to see the wave form and see where it fails - For testing you can pull freeze frame data for starting diagnosis but you will need a scope to finalize.

A hall effect sensor fault can be other items, e.g. the supply wire can be shared between other sensors, an internally shorted sensor somewhere else can give a fault on some other shared feed sensor.

Your "repair" cannot be termed repair - its called "shooting parts at the problem"

If your transmission has a mechanical problem then repair that too. But speaking from experience, asking these 660 cars to climb a hill is asking suicide from them. I drove a 660 car to nearly its death on the M1 motorway loaded with 5 passengers and luggage - The turbo was on constant boost and the turbine of it actually overheated. I also tested the sump tempearture of the transmission and it was at dangerous levels of 120C due to the high rpm experienced by the torque converter all the time.

btw - why have you took off the driveshaft for the AWD?

[zak82]

Will also get the wiring checked

One Question, cud a faulty wiring be giving such a problem?? Wudnt it be the hardware causing the Issue ?

[VCheng]

Wheels r not spinning. If they were,there was no issue ..

Then you are on the right track to look at causes other than traction.

[Xulfiqar]

a cut wire on any of the three that go into a hall effect sensor will pop a code as the sensor either is not working or the sensor is working but the signal is not reaching the computer.

I wud loved to have one installed to extract extra torque out of AWD but unfortunately, it came without the shaft

AWD only improves traction, not the overall torque available.

I have driven a Suzuki FX all over the northern areas myself, and it can go just about anywhere.

True that! Back in the days our 86 corolla automatic just died out on shogran charhaiyan wheres an fx jst cruised past us with its weird then ever sound!

The simple answer as eluded by many is lack of torque at lower rpms. Find a steep enough climb and try
pushing off from standstill in most autos and you will encounter similar issue. In most auto boxes the gear ratios are much taller than manual counter parts which doesn't help.

First time I experienced it was in Murree 1984, driving a 1983 corrolla 1.3 auto (3 speed) coming out of Cecil hotel towards Mall! It just wouldn't budge from standstill on steep inlcine. However with rolling start it would go up easily!

Have also experienced similar issues in Civic 1.8 (2007) in nathiagali, a car that can still crosses 200kmph easily on motorway!! No amount of left foot braking + full accelaration and sudden brake release to break traction to raise rpm worked. And the not recommended style of raising rpm in neutral and shifting to D didn't work either!

And than, once at Jheel Saiful Malook my TLC (1FZ 4500cc) almost did something similar! So don't sweat too much about it!

Once you are rolling the engine rpms rise n so do the torque / power numbers which helps to climb easily.

Pretty much right abt the civic
Add a Suzuki Baleno in the list as wel!
