I have searched and can't find my exact problem. I have a2000 convertible with 33k miles. A few months ago my battery went dead and was replaced. This began a string of problems that I can't help but believe aresomehow related. Was having no problem with any of these things before batt. problem.
#1: fuel gauge will go to empty when above 1/2 tank. did all the additive thingand still malfunctioning.
#2: TPM service message on DIC at random times. The receiver cannot locate thefront left reading which generates the message. I did the wheel sensor reset several times and will accept each tire with the horn blow. I is always the front left that it can't find. It is not giving me a low tire pressure warning but a service TPM system message.
#3: A/C air is colder on pass. side than drivers side. tried all of the reset suggestions posted here and had a little improvement but can still feel the difference in temp.
Today everything was working fine; the fuel gauge was below half and working,TPM was working and getting signals from all four tire sensors with listed tire pressure. I added fuel and was careful not to fill it all the way up to see if that would make a difference. Started it up and gas gauge read a little over 3/4. All going fine for about an hour and after several starts and stops. After an approx. 45 min. drive, the fuel gauge went to empty with associated warning(check gauges) within a few minutes of this the TPM lost contact with the left front tire and threw the "Service TPM System" message on the DIC.AGGGGHHHH :duh
Now I am thinking that these two things are related and that it doesn't have anything to do the fuel affecting the sending unit contacts or the wheel sensor not sending a signal but a problem with the receiver. The temp. difference on the dash vents is the only constant.
I am hoping that someone will read this and say; OH Yea, I had that same thing and it was a simple fix; just do this.........
I hate to bring it to the Dealer, even though they have a good Corvette mechanic; these types of problems usually result in lots of parts thrown at the problem and little results. Could it be a ground problem in the area of the TPMS and the fuel sending unit (I understand they are both located behind the drivers seat; could this be a coinsidence?)
I wait with anticipation for your knowledgeable input:thanks:
