Default Effect of incorrect setting of TPS sensor

Hi All,

Im trying to diagnose mileage issues with my maruti zen(old model)

This is my observation today.
Throttle Position Sensor voltage as per the manual is,

Throttle valve fully close: 0.78 – 0.83V
Throttle valve fully open: 3.7 – 4.7V

Im getting a reading of 0.76 V

My question is, is 0.76V acceptable?
Will it affect fuel cut operation?


Like i said, im trying to resolve high fuel consumption problem.

Note: everything else like plugs, filters, value setting, has been changed and engine serviced.

Default Re: Maruti Zen (MH410 16V) Sensor Codes

Hi there !

Can the members on this thread let me know if the Mahindra Bolero 2003 GLX has an ECU unit ?

I have a problem currently. The car will not start when the engine is warm.
The car cranks in one shot when the engine is allowed to cool and the key is turned.
Cranks fine when the engine is cool (mornings-first start)

Seems like the case of the coolant sensor or the cam shaft position sensor.

Hope I could solve this problem with some help from members in this forum.

HELP

Thanks!
Sai

Hi Sai
I dont know if your car has an ECU.

But even if there is one, the problem you mentioned cannot be related to coolant and cam shaft sensors.

Hi T1000!

Thanks for your input .

I've been going through quite a few threads online on the issue and was particularly going through a Honda and a Jeep thread that pointed to a defect coolant sensor issue and hence I mentioned the same .

I have just found out from a thread on TBHP that it could be a starter motor problem. I'm following up on that .

Shall post on developments ASAP
