Throttle Actuator Control (TAC) System Description
You have APP- accelerator pedal position sensors or one of the Throttle position sensors is going bad ! In the (TAC) system ! This is drive by wire or electronic throttle control . If you take it to the dealer or a ASE certified repair shop they can check the DTC'S - diagnostic trouble codes ! This is nothing for a DIYer to mess with ! This system can set 7 different DTC'S

Reduced Engine Power Mode When the PCM detects a condition with the TAC system, the PCM may enter a reduced engine power mode. Reduced engine power may cause one or more of the following conditions:
Acceleration limiting--The control module will continue to use the accelerator pedal for throttle control; however, the vehicle acceleration is limited.

Limited throttle mode--The control module will continue to use the accelerator pedal for throttle control; however, the maximum throttle opening is limited.

Throttle default mode--The control module will turn off the throttle actuator motor and the throttle will return to the spring loaded default position.

Forced idle mode--The control module will perform the following actions:

Limit engine speed to idle by positioning throttle position, or by controlling fuel and spark if throttle is turned off.

Ignore accelerator pedal input.

Engine shutdown mode--The control module will disable fuel and de-energize the throttle actuator.

P0332 - Knock Sensor 2 Circuit Low Input (Bank 2)

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

Causes for P0332 DTC:
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- PCM or ECM failure.

- Repair or resecure the harness or connector.
- Replace the knock sensor.

Your best bet is to just replace the knock sensor for sensor 2 bank 2. Call Auto Zone with part number SU1282 this is the OEM replacement.

The knock sensor looks like this:

You have to pull out the rear drive shaft and then unbolt the transfer case. Unhook the wiring and front driveshaft and pull the case off the transmission. Then change the gasket and reinstall.

Check wiring under the seat. Frequent habit of pushing things under the seat such as flashlights and tools etc and moving the seat forward and back sometimes pulls wires or breaks them.

If your problem is in all doors I'm probably wrong :) may find that an inner door jamb spring loaded switch has failed. It works exactly like the one in your fridge does, It triggers power to the light when the spring is out ,.. sometimes it gets stuck in you might just be able to clean and loosen it up.

check your radiator ,when cold take the cap off and look inside sometimes mineral deposits build up on the core and restrict the flow and the thermostat could be bad or if you used sealer on the thermostat housing you may have used too much and that could stop the thermostat from opening,look for the simple things first.

When the airbag light is on it means a fault has occurred in the system and the airbag diagnostic monitor has disabled the system, the most common problem that turns the light on is a break in the connection to the steering wheel mounted airbag, this is due to a rotating ribbon contact that breaks under the steering wheel that connects the airbag to the wiring harness and the diagnostic monitor, the part is called th clock spring contact, a coiled up ribbon electrical contact that turns with the wheel
