Why does the hatch back have a temp gauge?

I looked at a hatch back 5 speed before purchase of my sedan and saw another one the other day. Both have temp meters next to a gas meter where us sedan owners just get an idiot light.

Just wondering.

Yeah I was wondering that as well. A temp gauge would've been nice!

Maybe not as nice as you think. Some OEMs now include a gauge that is not a gauge at all, it is a simple unit that acts EXACTLY like a light. The PCM slowly moves the needle up as soon as determined the engine is getting warm, then the needle stays dead straight up until you hit overheat territory, then the PCM moves it slowly into the red zone. You think it works but nope, it is nowhere near linear for actual temperature at all. Put a scanner on the temps and the needle will be in the middle and not budge at all from 170 all the way to as much as 240 degrees (it can vary of course). The big joke on car buyers.

It's done since all cars vary a little bit since no way can all those mass produced gauges be dead accurate. Then picky buyers who get one that rises slightly too fast come back with warranty claims saying it runs too hot when there is nothing wrong at all with the car.

Same reason behind why so many engine issues now do not produce DTCs anywhere like they used to, say you get a car severely misfiring to not log any codes at all. The code logging has been heavily damped to make sure a thing can happen up to 10-50 times before a code ever logs depending on software and the particular issue.

Both those things are now often done to severely curtail warranty claims, if every instance of something going wrong logged a DTC the dealerships would be driven crazy with false issues that cannot be found when the car comes in for a check. It saves them millions of dollars.

That's why I use a Bluetooth obd2 and torque pro app.

Ah..... Yeah, I had a geo metro and a scangauge 2 and notice something like that. I just assumed the sg2 since it was digital was more accurate than the analog meter.
