P2106 P2110 P2135 P1516

code p2282 is a vacuum leak. because of it your PCM is going into LIMP HOME MODE. Check for a broken hose or intake manifold gasket leaking

b2106 - throttle input out of range high
b2110 - front wiper motor relay circuit
b2135 - parking brake warning light circuit

there are no "p" in the 2000 range in the list I have

p0122 - throttle a circuit input low
P0222 - throttle b circuit input low

Check to see what the input voltage is across the throttle circuit should be and meter. I would think perhaps there is a fault in a wire from the gas position sensor and the ecu? or did you wire the a and b circuit backwards? (high on low, low on high?) Good luck, that sounds like a pain!

P2110 - Throttle Actuator Control System - Forced Limited RPM. Throttle actuator control system is in FMEM mode of forced limited RPM.

• PCM damaged
• Cross wired TACM motor

DTC indicates only that FMEM condition exists, and can be set incombination with DTCS P2100, P2101, or P2107, meaning the ETB faults should be repaired first.
P2107 - Throttle Actuator Control Motor Processor. The ETC control area of the PCM failed self test. Fault could be the result of an incorrect TP command, or the TACM wires shorted together.

• TACM wire shorted together
• TACM circuit wires shorted to pwr
• PCM damaged
• ETB damaged

An (TACM) circuit PID reading may indicate a fault if available
DV21 CHECK ETC MOTOR FOR SHORT OR OPEN

Important: DO NOT replace the APP sensor. Inspect the PCM build date first.

Before following the diagnostic information in SI on DTCs P1516, P2135 and/or P2138, an inspection of the PCM serial number year and Julian (PCM build) date will be necessary to determine if the PCM will need to be replaced to correct the repeat DTC P1516. Refer to Engine Control Module Replacement in SI in order to remove the PCM. Refer to the above graphic illustration (1) for the location of the PCM serial number.

The serial number is read left to right. The last digit of the year is the 9th character and the Julian date is comprised of the 10th, 11th and 12th characters and is used to determine the PCM build date. Refer to the example below to read a build date from the PCM serial number:

* 8 6 Y N AU K 1 5 3 2 5 0 R P N *

If the PCM year and Julian dates are between 5182 and 5304 , replace the PCM. Refer to the Part Catalog to order the correct PCM for your vehicle application, if necessary.

Vehicles with PCM built outside the dates should refer to SI diagnostics for DTCs P1516, P2135 and/or P2138

(so i cleared the code..all was fine.) No it wasn't ,you don't just clear code's without doing the diagnostic's for that code . It's just a matter of time ,when the PCM/ECM - engine computer runs that test again, that light will come back on. P0455 is a large leak in the evaporative emission system .Sorry dude but you don't stand a snow ball's chance in guam of fixing this .
Do you know what electronic throttle control is ?
P2135 - ETC Throttle Position (TP) Sensor A/B Voltage Correlation Description: The powertrain control module (PCM) flagged a fault indicating that TP1 and TP2 disagree, or that TP1 should not be in the present position given the position of TP2 unless a concern is present. Possible Causes:

• TP sensor shorted internally to VREF.
• TP sensor harness is shorted to power.
• TP sensor signal wires are shorted together.
• Damaged TP sensor.

Diagnostic Aids: Compare the TP1 and TP2 PID values for a full sweep and correlation. Refer to the chart in pinpoint test DV. GO to Pinpoint Test DV .
Compare TP1 and TP2 PID values to the typical reference values in Section 6 . Application Key On Engine Off Key On Engine Running Continuous Memory All GO to DV4
P2110 - Throttle Actuator Control (TAC) System - Forced Limited RPM Description: The TAC system is in the failure mode effects management (FMEM) mode of forced limited RPM. Possible Causes:

• Cross-wired TAC motor.
• Damaged powertrain control module (PCM).

Diagnostic Aids: This DTC indicates only that the FMEM condition exists, and can be set in combination with DTCs P2100, P2101, or P2107, meaning the electronic throttle body (ETB) faults should be diagnosed first. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to QE1
Do yourself a favor an take it to a qualified repair shop.

These codes indicate your accelerator position sensor has malfunctioned. The computer has gone into limp mode, which allows you to drive to safety without damaging the engine. The computer is unable to determine how far you are depressing the accelerator and doesn't want to over-rev the engine. You need a new sensor.

TSB # 08-FL-004-1 CHECK ENGINE LIGHT P2135 DTC DIAGNOSIS....
there is a problem with the pedal assembly which has your throttle position sensor causing the codes, dealer only part you can install yourself with some know how

Code P1295,P2106 are malfunction in electronic throttle control. P2135 is a fault in throttle pedal position.It might have a crack in the intake manifold. Check with dealer for possible warranty.

This is what I find from other webpost..

Condition:
Some customers may comment on an MIL/SES light Illuminated with the" Reduced Engine Power" message or indicator displayed. A technician may find two or more of the following DTCs stored in the ECM:

P060E : Control Module Throttle Position (TP) System Performance

P1516 : Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance

P2135 : Throttle Position (TP) Sensor 1-2 Correlation

P2138 : Accelerator Pedal Position (APP) Sensor 1-2 Correlation

Cause:
A battery voltage drop during the cranking cycle may cause the codes to set and place the vehicle into the reduce engine power mode.

Correction:
Test and charge the battery using the steps below.

Important: A low voltage condition may cause at least two of the following DTCs to set.

P060E : Control Module Throttle Position (TP) System Performance

P1516 : Throttle Actuator Control (TAC) Module Throttle Actuator Position Performance

P2135 : Throttle Position (TP) Sensor 1-2 Correlation

P2138 : Accelerator Pedal Position (APP) Sensor 1-2 Correlation


Perform a Diagnostic System Check. Refer to Diagnostic System Check - Vehicle in SI.
Check for DTCs and review the Freeze Frame/Failure Records to determine if sufficient ignition voltage was present when the DTC set.
- If the ignition voltage was low, then check for a possible battery drain. Refer to Battery Electrical Drain/Parasitic Load Test.

- If the ignition voltage was sufficient when the code set, proceed with normal SI diagnosis for the code(s) set.

Test and recharge the battery using Bulletin 02-06-03-009 or latest version on "Battery Charging Tips'.
Clear all DTCs.
