If you want all the functions and data for a given vehicle you need the OEM scanner. $$$ No generic scanner will cover all the functions and at times the data is missing or wrong. Several brands of clones are available. They all use the same port and communication protocol is determined by the onboard computer so no, they do not access different pins in the ...

What I tried? I have recently (today) tested OBD II on my Maruti Suzuki WagonR made in mid 2013. I'm using some cheap quality Bluetooth BT connector (borrowed from friend) with Free version of Torque (OBD scanner/reader Android app). Live readings while driving car were good. Pretty much valid. No issues so far. I plugout the connector while leaving car as ...

Is it likely the extra oil messed up the oxygen sensors? I don't think so; not in a few days' worth of driving if the O2's were healthy to begin with. It is true that if engine oil has been overfilled, more of it will make its way to the exhaust where it will encounter the O2 sensors, causing them to foul, but the abuse would have to be over a longer ...

This is the calculation you're looking for. IMAP = RPM * MAP / IAT MAF = (IMAP/120)(VE/100)(ED)*(MM)/(R) Where manifold absolute pressure (MAP) is in kPa, intake air temp (IAT) is in degrees Kelvin, R is 8.314 J/°K/mole and the average molecular mass of air (MM) is 28.97 g/mole. Note that, in the above formula, the volumetric efficiency of the (4-cycle!) ...

First you need to look at all parts and how they work. MAF- uses two different sensors to regulate how much fuel goes into the motor based on the TEMPERATURE and AMOUNT of air going to the motor. MAP- only measures pressure not the temperature. This is pulled from the IAT which measures intake air temperature. That being said how a MAP based system ...

It is highly probable that the reason your car was reluctant to start was that the time you were running diagnostics had sapped some of the charge from the battery. The battery on the car will not charge unless the engine is running. It is unlikely that this device would harm your vehicle but it is theoretically (and practically) possible to do temporary ...

No. The tool in and of itself cannot do any "harm" to the vehicle. If you were testing apps with the engine off, it is quite possible that the battery may have drained to the extent that it gave some hiccups while starting. Low fuel level may also be to blame here. However, If the vehicle has error codes present which are cleared with the tool, the ...

To my knowledge there is no way a scanner can cause issues with your computer electronics. This device is a read only device. It doesn't change anything in your computer. It does, however, communicate with the computer. Through this communication it can give the computer commands, such as to clear the codes. This doesn't write anything to the computer, but ...
