What is the problem your having with this 2000 toyota tundra?

Posted on Aug 22, 2013

Testimonial: "The accelerator pedal is not responding and the engine is accelerated over 2300 rpm. He sent the code P1126 (Magnetic Clutch Circuit) so that replaces the throttle body completely. I lit the car with the new throttle body and the problem is still the same, did not change anything"

2010 3ltr turbo diesel changing throttle positioning sensor/switch under dash.when i take it off to replace it ,does it have to reset for electrical values thanks andrew


if the pedal is fully back on installation then it should not be necessary
basically your foot position on the pedal is the position sensor calibration and by moving the foot that calibration alters so the throttle body sensor reacts to that new calibration

Throttle body sensor


Some throttle bodies are simple and straightforward (not many) and some are complex and could contain electronics for correcting the non-linear response from the air metering device. Some have replaceable parts and others are considered to be a factory calibrated assembly where nothing is replaceable.

The throttle body can be a minefield of electronics, sensors and actuators and they should not be lightly considered - you need to know what you have and whether what you want to do with it is not just possible but also practical.

Where is the Iac located on a 97 get metro? I removed the throttle body but cannot locate it.


There is no Iac,here's a link to the throttle body.The air valve is calibrated at the factory and is not serviceable. No attempt should be made to remove it from the throttle body. If the air valve is defective, the throttle body must be replaced as an assembly. SAVE 20 ON ONLINE SHIP TO HOME ORDERS OF 100 OR MORE Here's another link to read.

DTC P0506

Circuit Description

The throttle actuator control (TAC) motor is controlled by the powertrain control module (PCM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

DTC Descriptor

This diagnostic procedure supports the following DTC:
DTC P0506 Idle Speed Low
DTC P0507

How to replace the TPS.


no engine option stated, and is key fact to know here.
eg:
The 5.7L V8 engine does not use a separate Throttle Position Sensor (TPS) on the throttle body.

remove old TPS, and bolt on new.
its like 2 or 3 screws. no big deal.
but needs to be calibrated per fsm.
ill take a wild guess, 3.7L
3.7L Engine and 4.7.
  1. Remove air resonator tube at throttle body.
  2. Disconnect TPS electrical connector.
  3. Remove two TPS mounting screws.
  4. Remove TPS.
install
The throttle shaft end of throttle body slides into a socket in TPS. The TPS must be installed so that it can be rotated a few degrees. (If sensor will not rotate, install sensor with throttle shaft on other side of socket tangs). The TPS will be under slight tension when rotated.
  1. Install TPS and retaining screws.
  2. Tighten screws to 60 inch lbs. (7 Nm) torque.
  3. Connect TPS electrical connector to TPS.
  4. Manually operate throttle (by hand) to check for any TPS binding before starting engine.
  5. Install air cleaner tube to throttle body.
some TPS need calibration
to see what yours needs, read the FSM
or at alldata.com
or here. I think all engines here, are TPS PCM autocalibrated.

that thing that sucks air,
do not fiddle it, its calibrated on car, read the FSM for how to
test it or calibrate it.

Electronic throttle control light is on


Hi. The system uses a sensor that positioned on the throttle body to control acceleration. The sensor is called the Throttle Body Position Sensor. That needs to be replaced. But its not as simple as just replacing it. The cars computer then needs to be calibrated to the new sensor. normally this is a simple task however in my experience with your ford it wasn't that simple. It needs to be calibrated using a Special diagnostic tool. This one isnt a DIY fix, you will need profession help. But the good news is its an easy fix and shouldnt take more than an hour and is cheap as well. Its just you need someone with the skill set,

But i should also mention that I didn't need to replace the sensors in most of the vehicles. The solution was to remove the sensor, I sprayed it out with WD40 and contact cleaner, let it dry out and then put it back in, When the vehicle started it idled roughly for a few minutes and then started working fine.

If you wish to attempt that yourself , locate the throttle body (look at where the acceleration cable connects and you will find it). locate the sensor, (only one with wires coming out of it on the throttle body), remove it, clean it, replace it.

Do all 1991 ford f150 5.0 L engines have a TPS and if they do where should it be located?


What you are looking for is a part that looks somewhat like this:


all-1991-ford-f150-uieet1hkvzpdkwtaumvt01gh-1-1.jpg

...and is located on the part shown below (most likely on the bottom, just above the label "Bolts"). The mounting screws will be hard to get at - either take the throttle body off or use a stubby screwdriver to get at it.

all-1991-ford-f150-uieet1hkvzpdkwtaumvt01gh-1-3.gif Note that as soon as you loosen the screws, you may throw it out of calibration. When reinstalling the sensor (or installing a new one), you will have to calibrate it. Refer to your vehicle's repair manual for the exact values to measure when calibrating this component.

2001 Ford Taurus idels low and stalls sometimes when stopping at a stop light


sometime this will happen if the throttle blade idle hole gets plugged with carbon. if you take off the air inlet tube off the throttle body and look into the throttle body you will see a round looking flat disk , you will see a small hole in it .about the size of a stir stick straw .this hole gets plugged with carbon and will effect the idle.it calibrated to let the right amount of air in the engine @ idle.if you clean this there is a good chance this will fix your problem . be careful what cleaner you use as some of the throttle blades are coated with a Teflon coating(local parts store will have the proper throttle body cleaner for these ford throttle bodies )

On a 3.5 engine code reads low idle? any idea


LOW IDLE CAN BE CAUSED BY MANY THINGS.CLOGGED AIR FILTER. LOW COMPRESSION OR MISFIRE CONDITION.IDLE AIR INLET PASSAGE OR THROTTLE BORE IS DIRTY OR FULL OF DEPOSITS.IDLE AIR CONTROL VALVE FAILED.MASS AIR FLOW SENSOR COULD BE OUT OF CALIBRATION. THROTTLE PLATE THROTTLE SHAFT OR LINKAGE IS DAMAGED OR STICKING.PROBABLY HAVE REMOVE THROTTLE BODY ASSEMBLY REMOVE IDLE AIR CONTROL VALVE AND THROTTLE POSITION SENSOR.BUY CAN OF CARBURETOR OR THROTTLE BODY CLEANER SPRAY CLEAN ALL CARBON BUILT UP AROUND THROTTLE PLATES AND BORE.LET AIR DRY BUY A NEW THROTTLE BODY GASKET.
