Throttle problems - 2007 Dodge Caliber 2.0

The 2007 Ford Explorer Sport Trac does not utilize the once-common idle air control (IAC) valve. Instead, an electronic throttle body is used. An electronic throttle body is a traditional butterfly throttle valve that has an electric motor attached to it. Instead of opening via a throttle cable, it is opened by the powertrain control module (PCM) when the accelerator pedal position (APP) sensor (which is the gas pedal) is pressed. The PCM also adjusted the throttle blade position in order to achieve proper idle speeds. Often times idle problems with this type of electronic throttle body are caused by carbon buildup around the throttle plate, in the bore of the throttle body. In fact, this is such a common problem with this particular vehicle that Ford released technical service bulletin (TSB) #12-7-4 to address the RPM fluctuation and hard start symptoms and advises to clean the throttle body. Alternatively, the throttle body can and may need to be replaced.

Reduced engine power is a problem with the electronic throttle control . You need to have a scan tool hooked up to read codes stored .

REDUCED ENGINE POWER: Refer to Powertrain Control Module Description in Engine Controls - 4.8L, 5.3L, and 6.0L

Reduced Engine Power Mode
When the PCM detects a problem with the throttle actuator control (TAC) system the PCM enters one of the following Reduced Engine Power Modes:
• 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.
• 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.

Have you had it to the dealer ? May have TSB - technical service bulletin. TSB'S are factory technical information publications on know problems with fixes for dealer technicians . May also have up dated soft ware for your vehicles PCM - powertrain control module that may fix this problem . Could have a problem in the
Throttle Actuator Control (TAC) System - Electronic throttle control .Not all problems set trouble codes . And all car manufacturers have some problems with these systems .
The throttle actuator control (TAC) system delivers improved throttle response and greater reliability and eliminates the need for mechanical cable. The TAC system performs the following functions:
?€¢
Accelerator pedal position (APP) sensing

?€¢
Throttle positioning to meet driver and engine demands

?€¢
Throttle position sensing

?€¢
Internal diagnostics

?€¢
Cruise control functions

?€¢
Manage TAC electrical power consumption

The TAC system components include the following:
?€¢
The APP sensors

?€¢
The throttle body assembly

?€¢
The TAC module

?€¢
The powertrain control module (PCM)

At the throttle pedal.

Clean the throttle body and add Seafoam to the fuel tank and run out a tank of fuel, check for worn or sticky throttle plate,
if none of that works check the plug on your gas peddle and the plug at the throttle actuator on the throttle body for corrosion and tight fit, if no problems found, you may need any one of the three components
the throttle actuator
the throttle peddle position sensor
the ECC or ECM (engine computer) (check all plugs on it too)

c121cThis has to be checked by someone with a computer capable of communicating with all the systems/computers in the vehicle to determine what is wrong here. you have a problem with you electronic throttle control .
P0123 throttle position sensor . You need a new throttle body or have a wiring harness problem !

Electronic Throttle Control ETC System Electronic Throttle Control ETC System

P2110...Faulty Throttle Actuator Control Module
- Throttle Actuator Control Module harness is open or shorted
- Throttle Actuator Control Module circuit poor electrical connection

P2118 - Electronic Throttle Control(ETC) system is made of the components throttle body, Throttle Position Sensor(TPS)1&2 and Accelerator Position Sensor(APS) 1&2. The throttle body contains the actuator, the throttle plate and the throttle position sensor (potentiometer), which are integrated in one housing. The actuator consists of a DC motor with a two-stage gear. The opening angle of the throttle valve is detected by the throttle position sensor which is mounted on the throttle body. And it provides feedback to the ECM to control the throttle motor in order to control the throttle valve opening angle properly in response to the driving condition.

Hello, the first thing you need to do is check the throttle body bore for carbon build up. pretty common to have the the throttle body build up carbon between the throttle bore and throttle plate causing some unstable idle problems. you can clean out the throttle body bore with some throttle body cleaner and a shop rag

make sure nothing is caught holding the plate open,disconnect the throttle cable from the throttle valve at the intake.if the throttle closes then i would say you have a problem with the cable itself and will need to be replaced.make sure there is nothing caught at the gas pedal that is holding open.if the throttle stays open then you may have a problem with the throttle shaft(dirt build up),bent shaft,damaged throttle plate,loose plate(has screws holding plate in position)on the shaft.it could also be a bad tps sensor(throttle position sensor)that is damaged internally and needs replacing,as it is fasten to the opposite of the throttle shaft from the cable.if you remove the screws(note position of sensor and screws on sensor)and remove the tps and the throttle is not stuck then this is probably the problem and needs replacing.

We actually have a TSB for the drive by wire systems that calls for both a TPS sensor/actuator replacement but it's required that you also do a PCM reflash at the same time. If you put in the new updated part without doing your reflash then you've found your problem.

Take it to the dealer and get the reflash done.
