if the car won`t turn over then it could be a starter problem if the battery is as you say fully charged. check voltages at the starter. it could be a bad connection or starter relay.

Hi Pamellaa to reprogram the sunroof do this procedure Good luck

Knock sensor controls ignition timing. It should have no control on transmission shifting. Did you disconnect/remove anything else to access the knock sensor? Was the battery disconnected? If so, a relearn procedure may be required for trans module etc relearn shift points while you drive the vehicle

Kick down is a cable. Look at the throttle body. This is usually where the cable breaks. Small plastic clip that hangs on a post.

No it's built in seatbelt

Probably a loose or corroded connection in the master window switch. Sometimes if a window is down when it is raining the switch will get wet and cause some corrosion on the contacts.

Sorry Scott no inertia switch , Two relays , circuit opening relay an the other is Engine main relay if the wiring diagram is correct , hard to tell ! Japanese wiring diagrams ! go to www.bbbind.com free TSB'S an Wiring diagrams .

The pump is inside the gas tank. Only Ford products us an enertia switch.

the remote key would be the easiest (and cheapest) thing to try first but i don't think that a low battery in the fob would activate the alarm randomly , i'd get the OBD codes read as will point to which part of the anti theft/central locking system is causing the issue

check vehicle speed sensor and / or plug/wiring to that sensor

You have a bad ground wire somewhere; probably right off the drivers side door. It may be difficult to locate because all the window switches are wired to the master control switch on the driver side door. I often find the wire breaks somewhere in the conduit between the door and the dash. All the opening and closing of the door damages the wire, particularly when the wire doesn't have any room to flex. Once you find it and bypass the broken connection all the switches will work. Start with the connections on the switch and work your way to the dash. You probably can find a good YouTube video that can show you how it's done. A multimeter will be very useful checking the continuity of the wires. I like to disconnect the switches in both the driver and passenger doors. I will then use a piece of wire to bridge the connections on (passenger) door connector, or ground out to the vehicle body. You can use the multimeter probes on the driver side connector to find the broken connection without tracing the whole wire harness. There should only be one hot wire that is supplied with power on the drivers side connector. Use the multimeter to find the hot wire first, using the vehicle frame as the ground, and then ignore it. Once you find the color of the wire that's broken you can just follow it along the wire harness till you find the break.

There is a pressure sensor in the gas tank that isn't working correctly. The engine will not run correctly without the battery because the alternator will not produce voltage for the electronics or the fuel pump.

there will be a air flow setting knob that controls whether air is defrost or on feet or from the console vents.

take it to jiffy lube

Also Known As Vehicle Speed Sensor usually held down w/ a small bolt on the transmission case speed sensors on transmission Club Lexus Forums read the following thread by car owners of your same make / model! they even included pics of the sensor

This could be caused by a variety of things.....but, coolant temperature is a significant input to the transmission control module for the overdrive gear engagement. If the transmission ECU determines the engine is not coming up to operating temperature, it will delay the engagement of the overdrive. There is also the possibility that the throttle position sensor has an issue as well....is the check engine lamp illuminated??? A scan of the engine control module and the trans module is in order....a good tech. will be able to discover the cause very quickly!

FIX/CHECK IGNITION COIL FIRST, BEFORE YOU DO ANYTHING ELSE

Do you have a bad connection to the speed sensors, what are the symptoms? Does this help? https://www.youtube.com/watch?v=wpgC9Nf812s

not sure but I will say this. most timing sets should be changed every 75 to 100k miles. its cheaper to change the belts and water pump then to pull the motor and spend thousands on 10 dollar bent valves

this a rear wheel sensor. Hope this will answer your question,If do pls click on helful botton and you can follow me at fixya,so I can answer your question faster.thanks.
