Hello all. I have a couple questions concerning some maintenance issues on my car I thought I would run by you fine folks.
First, my TPMS system has a bit of an annoying issue. Namely, it is reading about 3 PSI lower than reality, as determined by two separate pressure gauges, and thus giving me low pressure warnings when the tire pressure is actually dead on. This only is an issue with the front wheels, but they are set at 32 PSI cold, and I'm still getting a low pressure warning all the time. When I start the car, it reads typically reads either 28 or 29 PSI on the guage cluster, and gives a warning. Checking the pressures shows them to be set correctly though. Any advice here? is there a way to recalibrate the TPMS sensors, or do I just need to overinflate the tires and deal with the horrible ride quality if I want to get rid of the error message? Also, why in the world are the rear tire pressures recommended to be 37 PSI? That seems really high. Never had a car that recommended over 32 before.
Second, I'm having an issue with the car being slightly difficult to start at times. It's especially true when it's hot, and I stop the car for a little while then attempt to restart it. It does actually start, at least so far, but it feels like the starter can barely turn the engine over and it takes 3 or 4 revolutions for the engine to fire. I checked the battery last night, and it reads 13.8 volts with the car off. 14.4 when the car is running at around 2k RPM, so it seems like the battery and charging system are working. the battery itself is less than 2 years old according to the maintenance records. Any thoughts on what might be causing this issue?
