Have the history codes read. This will give you an idea where the problem is. Anytime the light comes on, it is stored in the ECM. If the light goes off, then it is stored in the history codes..

SOURCE: how to reset the check

That means that the sensor must be replaced.

You can turn temporarily off the light by disconnecting battery for five minutes, but it will probably come back.

To fix it completely, take it to a garage and have the problem fixed.

Note: when you unplug battery you may be asked car radio security code afterward.

Denalis are famous for clogged fuel filters. Change the fuel filter first and see what happens, Get the code for the check engine light. It could be you have a clogged EGR ports. Remove EGR valve and clean out the ports, replace with new gasket and see what happens. Advise of results.

SOURCE: whining when not accelerating

Loosen and remove the Alternator belt which may be a serpentine belt and see if the whining goes away.
It could be the alternator or the water pump if it's driven by the same belt. It will go away while moving because the engine noise is usually negated by road noise etc but it's probably still there.

SOURCE: 2002 Highlander - water gets into wheel well

The area under the spare tire in my 2002 Highlander has been filling with water, sometimes becoming so full that it overflows when driving and soaks the carpets all the way up to the front seats. The problem, which I finally figured out today, was small cracks, just above the point where the air cylinders that hold the tail gate open are connected to the body. The cracks on both sides were apparently never sealed during assembly. Water flowing back over the top is supposed to enter the slot between the roof and the top of the tail gate, flow down either side, and then exit over the rear bumper. In my case, water was flowing into the aforementioned cracks, down inside the vehicle, and accumulating in the wells on either side of the spare tire compartment, as well as the area under the spare time. My solution was to seal the cracks with a silicone sealent. This has to be a design or assemble fault, but the fix was too simple to bother the dealer. Now I just neet a week of sunshine to dry the Highlander out.

it is possibly the throttle position sensor(tps) malfunctioning. basically the computer or "brain" of the car thinks the throttle is in a different position than it really is and automatically makes adjustments to fuel, air ect.... based on these false readings from the sensor thus causing the engine to react a little different when you expect to have power.

Maintenence required light and tire pressure lights will not go off after oil change and tire rotation on my Toyota Highlander. How do I turn them off?


The maintenance light needs to be reset manually. See my Tips and Tricks on this website for additional information on how to reset it.

You should also check your spare tire for proper inflation. It will set the tire pressure light, as the spare is monitored also. If all 5 tires are OK, you may have a malfunctioning tire pressure sensor. If the tires have been changed recently, people with older tire machines have been known to break the sensors regularly, by mistake.

Car will not accelerate in high gears, and does


Ok... do you have the maintenance history on this vehicle? Did the 'Check Engine' Light come ON? Whenever the 'CHECK ENGINE' light comes on, the ECU (Engine Control Unit) sets a Diagnostic Trouble Code (DTC). These codes identify the particular engine management system which caused the light to come on. You'll need to use/find an OBDII (On-Board Diagnostic) Scanner to retrieve any code which have been stored in the ECU computer. Afterward, we might be able to help you DIAGNOSE and perhaps eventually fix the problem.

Check engine light flashing


Whenever the "Check Engine" light comes on, there is always a DTC (Diagnostic Trouble Code) stored in the ECM (Engine Control Module). You'll need an OBDII (On-Board-Diagnostics) scanner to retrieve any codes recorded/set in ECM. Once you do this and let us know what, if any codes are set, then we can go from there. Could be ignition, fuel, vacuum leak, throttle position sensor, crank position sensor, etc., etc., etc.
