CV Joints are the most common cause.
The most common cause for a 2002 Toyota Highlander's gas gauge to be stuck at three quarters of a tank is a faulty sending unit. The sending unit is designed to detect the current fuel level and relay it directly to the gauge.
I have a 2003 Highlander. Whenever I get the oil changed, the check engine light comes on within a couple of days. I finally figured out that there is a hose under the air filter case that gets disconnected when the filter is checked. Just reattach the hose and the light will reset after a few restarts of the engine.
The ECU has detected a problem with the emissions system. Have the ECU scanned with an OBD2 scan tool to retrieve the code that has been set. This code will tell you where to start looking for the problem.
The Camry could have a vacuum leak. If there is a vacuum leak, then there can be a whistling sound until the vacuum system is full of air.
Any fault that affects emissions will turn the light on. You need to have it checked for codes to know possible causes.Any fault that affects emissions will turn the light on. You need to have it checked for codes to know possible causes.
