Hi Everyone,
I'm a newbee. Just joined.
Just got this second hand Brava 1.4SX last week. It's a nice car and drives fine. However, I hit a couple of problems. It might all be my own fault (being a total amateur on cars!). :bang:
I've read through most of the threads about Injector Warning Light and Temp Gauge (on dash) issues, but the symptoms are slightly different to mine.
1) Injector Warning Lights Coming On:
------------------------------------
During the past week, whilst driving the car, this light sometimes comes on (could be after a few miles or sometimes after 10-20miles). When it does, it stays on until I stop the car and turn the engine off. When I stop and restart the car, it disappears, and might not come on again for the rest of the journey. The next day, everything looks back to normal, then later on in that day (or perhaps stretching to the following day). Then, the warning light would come back on again (I don't rev the engine in anyway).
The only thing I did (before I noticed the light coming on) was that I cleaned the throttle body with carb/injector cleaner as it was covered with (what I think) was oil. I suspected perhaps the previous owner may have put too much oil, as there was some oil around the throttle body and in the little tray around the throttle body (which I mopped up as well). Anyway, the cleaner did the job, and there is no more oil around the throttle body or in the tray since I cleaned it up.
I read up some info that the IAT sensor is an integral part of the single point injector unit. Could I have damaged this sensor with the injector cleaner ?
As far as I can tell, I do not feel loss of power when the warning light comes on, so it does not look like the injector is damaged.
2) Temperature Gauge always near Cold:
---------------------------------------
Even after travelling over 100 miles, the pointer on temperature gauge only moves a little beyond the "C" (cold) mark. Does this means the thermostat is faulty ?
So far I have not yet seen the electric cooling fan kick in, but when I checked it, I had only driven the car for ~15mins, so perhaps the engine has not reached the kick-in temperature (I could just about put my hand on it - so most probably the case).
At this stage, I suspect the coolant fan switch may be faulty as well (and/or perhaps the cooling fan is not working either). I plan to check the cooling fan switch and cooling fan, do radiator flush and change the coolant (it's looks quite muddy brown).
Any suggestions ?
..sigh.................
Oh well, perhaps I really overlooked the obvious this time, i.e. the engine compartment!
Apologies for such a big thread. I thought if I give as much details as possible, someone might spot the obvious.
Thanks for reading the thread.
More thanks for any help/suggestions. :worship:
Best Regards,
Chuck
