It maybe your Fuel Sensor, or Fuel regulator is bad. Ask dealer if there is a TSB on it, just in case it is a recall on a part that is defective and get a free fix if it is.

The check engine light is on to tell you that the ECU has detected a fault. The faults are stored as codes. The codes both have to do with a deficiency of exhaust gas going through the EGR valve. You will need to find out if the problem has to do with the valve, a leak, or the circuit.

I have a 2004 Dodge Ram 3500 why do codes p0483,0541,0243,2121,2127 keep coming up what do these codes keep coming up


To get the meanings of these codes go to
http://www.obdii.com/obdii.html
P2121 - Check with dealer on this code
P2127 - Accelerator Pedal Position (APP) Sensor 2 Circuit Low Voltage
P0483 - Cooling Fan Rationality Check Malfunction
P0243 - Turbocharger Wategate Solenoid 1

If you are located near a National Auto Parts store (AutoZone, Pep Boys, etc.) I would take the truck in and have them run diagnostics.

Check engine lite is on, power lost lite is on. code p1276comes up. replaced throttle body, but no change. volts at vac fuse 14 both sides. will not accelerate over 1800 rpm's. 2004 trailblazer with 6cyl.


Your CODE P1276 refer to the Acelerator Pedal Position, Sensor 1 Circuit Range Performance.

Probable cause: Wiring, APP or ECM


GM - P1271 Accelerator Pedal Position Sensor 1-2 Correlation

I also found this... though its for Trailblazers... but may give you a clue:
Reduced Engine Power Message and/or Check Engine Light with any Combination of the following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682 #PIP3192 - (Oct 18, 2004)

Reduced Engine Power Message and/or Check Engine Light with any Combination of the Following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682 PCM Repeat.

The following diagnosis might be helpful if the vehicle exhibits the symptom described in the PI.

Condition/Concern:
Reduced engine power message and/or check engine light with any combination of the following DTCs: P0107 P0112 P0122 P0452 P1120 P1220 P1221 P1271 P1275 P1280 P1481 P1515 P1540 P1633 P1635 P1639 P1682

Recommendation/Instructions:
If the SI diagnostics did not isolate a concern, the following information may be helpful:
- Inspect the main engine wiring harness between the PCM and the generator assembly for a potential short to ground. There is a metal wiring harness retainer in this area that secures the main engine harness. If the harness conduit is mispositioned, some of the wiring may become exposed and chaff on the harness retainer. This may eventually cause the exposed circuit to short to ground.

- Inspect the 3 harnesses that connect to the PCM for potential shorts to ground on the metal PCM mounting bracket, just below the PCM. There are plastic harness retainers on the PCM bracket that secure the harnesses to the PCM bracket. If the harness conduit is mispositioned, some of the wiring may become exposed and chaff on the PCM bracket. This may eventually cause the exposed circuit to short to ground.

- If a chaffed circuit is found in either of the above locations, repair the circuit using the necessary SI procedures. Once the circuit is repaired, tape the area of the affected area of the harness to prevent the wires from becoming exposed in the future and secure the harness using the original harness retainer.

This applies to 04:
- 4.2L 5.3L LL8 LM4 Engine with DTC - P2120 or P2122 or P2123 or P2125 or P2127 or P2128 - kw low MIL pedal power reduced #PI01746 - (Feb 17, 2004)
- 4.2L 5.3L LL8 LM4 Engine with DTC - P2120 or P2122 or P2123 or P2125 or P2127 or P2128.

When servicing the vehicle with the VIN you entered, the following diagnosis might be helpful if the vehicle exhibits the described symptoms.

Condition/Concern:
MIL light on. Reduced Power message on DIC. Possibles DTCs P2120 and/or P2122, P2123, P2127, and P2128.

Recommendation/Instructions:
The APP harness is clipped to the accelerator pedal bracket. The harness may chaff on the upper portion of the accelerator pedal causing a short to ground. Verify the harness is not chaffing on the accelerator pedal. After repairing the short, reposition the harness to ensure no contact between the harness and the accelerator pedal.

Hope helpes.

Check engine light


Go here and it will tell you how to get your codes. Actually on an 06 you can just turn the ignition on and off 3 times (dont crank the engine) and the codes will show up on your odometer. But here are all the codes. PS you can get a manual on pdftown.com for free too.
