If the check engine light in your Toyota RAV4 comes on along with the VSC and 4WD lights, there could be various underlying causes. Possible culprits include a loose vacuum hose, a faulty O2 sensor, or a potential software glitch in the PCM. It is recommended to utilize a diagnostic tool to scan for error codes, which can be rented from a nearby auto parts store if you do not own one. This OBD diagnostic tool typically aids in identifying the root of the problem. Additionally, inspect all hoses to ensure they are securely fastened to prevent any air leaks.

Hello, my Check Engine Light, VSC, and 4WD lights suddenly turned on, and at the same time, my engine started running rough. I'm wondering if this could still be a problem with the cap? Would the engine not lose performance if it was related to the 'Cap'? Thank you in advance! 😊

So, I had an issue with my car where the heater wasn't working and some warning lights came on. My husband figured out that the antifreeze was low, which was also confirmed by a diagnostic at Autozone. He topped it up and the problem was solved, all for just $20. Interestingly, when you take your car to Autozone, this solution pops up on their computer diagnostic tool.

I received a phone call from a buddy who had to exit the highway because the check engine light turned on in his car. He was driving a high-mileage vehicle with 180,000 miles on it. I suggested that he check the oil level. When he did, he noticed that there was no oil shown on the dipstick. Fortunately, he had some extra oil on hand and ended up adding nearly 3 quarts to bring the level back up to normal! That resolved the issue. It's clear that his old engine is consuming oil.
