99 lexus es 300 chk engine and trac lock lite on

cylinder 2&3 misfiring, inspect plugs if ok, mark and swap coil packs for known good ones clear codes, run eng brake torque it rev to cause missfire, repeat until check eng, lite comes on, recheck codes if changed cylinders replace coil packs if not, you have two bad injectors.

my 1997 lexus es 300 engine light and trac light on.

Go to auto zone check codes it is free, ABS is the problem could be the hub bearing sensor is bad because 99, could be the bad wire broken in a loop near the wheel, worst is ***** wire, low voltage.

A week ago, on my Lexus ES 300 (2001), "Check Engine" and "Trac Off" lights came on. This coincided with me filling the gas tank to the brim to round the dollar to be paid. I cleaned the gas tank cap and the tank opening. However, both lights persisted. On the same day, when I turned on the car again, there was a hesitance, a stuttering to come on. Both "Check Engine" and "Trac Off" lights were still on.

The next day, the car wouldn't come on at all. It sounded as the battery was dead. I couldn't even jump start the car. So, I got a new battery from Costco ($59) and put it in. It took 15-20 seconds of cranking to get the car started. Once it was started, the engine sounded fine and the RPM normal. The "Check Engine" light was off. However, the "Trac Off" was still on. I cleaned the gas tank cap one more time.

The next morning, when I turned the car on, there was no problems. It came on instantly as it used to be, didn't have any warning lights, and drove smoothly.

if u disconnect the battery and the light comes off, but then comes back on that means that there is something wrong. It could be something simple or could be major. only way to know to bring it to the dealer or repair shop and have them hook up a scanner to it. as far as the Trac off light, that comes when the check eng lite comes on. your vehicle turns off the traction control (trac off) when u have a fault code which is why the check eng light is on.

try to reset this problem , disconnect the negative battery terminal few minutes and reconnect , start the engine

well, the first to do is an oil service to your car, after disconnect the negative battery terminal few minutes to reset

need to scan computer before you do anything else.

Variable Valve Timing , is an engine feature but is not a problem

Unscrew the gas cap, wait 30 sec and screw it back on making 3 clicks/cracks. Should be ok in a day or two.
