One of your actuators(electric)in climate control system is skipping a tooth, to isolate which one you can get a helper to turn the key on and listen under dash to check which one is causing noise.the actuator will need to replaced.

I need to replace the air conditioner blower fan on my 1996 Jeep Cherokee Sport.

You need to pull the blower motor (under dash on pass side) and vac out the debris that is in the ducts. If the fan is turning, you may have had a mouse take up residence in the heater, and there is stuff hitting the blower as it turns. Hope this helps.

No throttle response

What you replaced is the APP(accelerator pedal position) It is part of the electronic throttle control,what was truly needed is know as the TAC MOTOR. This recieves signal from the APP.The TAC is what accelerate the car.The only thing you can do other than replace the TAC,is do a TAC relearn .Turn thhe key off. wait ten seconds,Turn key on with the engine off.leave 1 minute. Turn key off start the vehicle you will hear the TAC motor setting itself.

I got codes P 2104 & P 2112 - what is this and how can it be sloved?

P2104 - Throttle Actuator Control (TAC) System - Forced Idle
P2112 - Throttle Actuator Control (TAC) System - Stuck Closed.
P2104 was set because the pcm had to step in to set the idle. The TAC system is in the failure mode effects management (FMEM) mode of forced idle. P2104 is just an informative code, set because of P2112. P2112 possible causes: Binding throttle body, stuck closed or
Damaged PCM

tell your dealer technician to follow pinpoint test DV1 in the workshop manual. (but also to reference test QE1) DV1 deals with him/her checking the throttle position voltages, if these voltages are not within spec, proceeding with checking for obstructions in the throttle body, then if this passes, he/she checks the wiring to the TAC assembly. there are many steps in this test and since the truck isnt here i can't tell you where the test will go (throttle body assembly, PCM, etc.) most likely it will be the throttle position sensor which is a part of the throttle body assembly or a simple connector coming unplugged or wiring being cut, but once again since i dont have the truck in front of me i can't be 100% sure. good luck. hope this helps.

Waht ist tha p1516

DTC P1516 - Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance


Circuit Description (click over pic for zoom)
The commanded throttle position, based on accelerator pedal position and possibly other limiting factors, is compared to the Actual throttle position. The 2 values should be within a calibrated range of each other. Both the PCM and the TAC module redundantly monitor the Commanded and Actual throttle position. This DTC sets if the TAC module detects the problem.

Conditions for Setting the DTC
1. DTC P1518 is not set.
2. The ignition switch is in the crank or run position.
3. The ignition voltage is greater than 5.23 volts.
4. Not in battery saver mode.
5. The TAC module detects that the commanded and actual throttle positions are not within a calibrated range of each other or the PCM and the TAC cannot determine throttle position or both TP sensors are invalid.
6. All above conditions met for less than 1 second.

Action Taken When the DTC Sets
1. The PCM will illuminate the Malfunction Indicator Light (MIL) when this diagnostic runs and fails.
2. The Reduced Engine Power message displays on the drivers information center.
3. The PCM records the operating conditions at the time the diagnostic fails. The PCM stores this information in the Freeze Frame and/or Failure Records.
4. If no other TAC System DTCs are set, the TAC System will operate in Reduced Engine Power mode. If certain TAC System DTCs are set at the same time, the TAC System either defaults to a more tightly restricted mode of operation if the TAC determines that limited safe operation is possible, or the TAC commands the engine to shut down.

Conditions for Clearing the MIL/DTC
1. The PCM turns the MIL OFF after three consecutive drive trips that the diagnostic runs and does not fail.
2. A last test failed (Current DTC) will clear when the diagnostic runs and does not fail.
3. A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.
4. The PCM battery voltage is interrupted.
5. Important
* The clear DTC info function may have to be performed twice in order to clear a Throttle Actuator Control System DTC.
* Clear the MIL/DTC information using a scan tool.

Diagnostic Aids
The following may cause an intermittent:
1. Poor connections. Check for adequate terminal tension. Refer to Troubleshooting Procedures, Checking Terminal Contact (Body and Accessories/Wiring Systems) for proper procedure.
2. Corrosion
3. Mis-routed harness
4. Rubbed through wire insulation
5. Broken wire inside the insulation
6. Inspect the TAC module connectors for signs of water intrusion. When this occurs, multiple DTCs should be set and no circuit or component problems can be located.

1. For an intermittent condition refer to Symptoms .
2. If a repair is completed and the DTC was cleared using a scan tool on the same ignition cycle, the default action will not clear until an ignition cycle has occurred.
3. When the TAC module detects a problem within the TAC System, more than one TAC System related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing one individual problem may correct more than one DTC. Keep this in mind when reviewing captured DTC info.

Test Description
The numbers below refer to the step numbers on the diagnostic table.

5. If the TP Indicated Angle does not follow the movement of the throttle blade, and no TP Sensor DTCs are set, there is a mechanical problem with the throttle shaft or the TP Sensor. Replace the throttle body assembly. Re-install the air inlet duct after you complete the repairs.

21. When a problem is detected within the TAC System, more than one TAC System related DTC may set. This is due to the many redundant tests run continuously on this system. It is possible that locating and repairing one individual problem may correct more than one DTC. Keep this in mind when reviewing captured DTC info.







Hope helps.

I have a 2004 Toyota Tacoma. During the last 2 months when I start the truck in the morning I hear a "tac, tac, tac, tac ...." noise for 30s to 1 min than it stops when I drive away. This...

This is most likely a noisy lifter (or valve tappet). In cold weather, the clearances in the valve train open up because metal contracts due to the cold. Once the oil pressure comes up after start the noise goes away because the larger clearance fills with oil and the lifter becomes "cushioned" with the oil. The proper fix is to have the valves adjusted. I believe in your model, that is done by putting shims on the lifters. This will quiet the noisy lifters. In the short term, you can try using a lighter weight oil for cold weather. This will get the oil to the lifters faster after start up and quiet the tapping more quickly. Once the weather warms again, shift back to the normal weight.

Toyota tercel flasher replacement

Try this before you pull the dash. Turn the ignition switch on, then, by hand, move the turn signal on an off slowly, while at the same time look under the dash. As the turn signal goes on and off each time you move the handle, you will be able to hear it click. Follow the click and you may find it is within reach without pulling the dash.
