did you type 3081 or 10010375 in for the NHTSA number.

 

2 websites say 10010375 is the NHTSA number

and 1 website says 3081 is the NHTSA number

Models:2001-2003 Chevrolet Astro, Blazer, Express, S-10

 

 



2001-2003 GMC Jimmy, Safari, Savana, Sonoma

This bulletin is being revised to delete a model and add information to subject and inspection of distributor vent screens. Please discard Corporate Bulletin Number 03-06-04-041 (Section 06 - Engine/Propulsion System).

 

Condition

Some customers may comment on poor engine performance and the Service Engine Soon/Check Engine light being illuminated. Upon investigation, the technician may find DTC P0300 set.

 

Cause

This condition may be due to high levels of internal corrosion in the distributor, causing misfire, rough idle, stall and Engine Cranks But Does Not Run. This corrosion is attributed to a lack of airflow internal to the cap caused by the vent screens being clogged with debris.

 

Correction

Remove the vent screens and inspect the internal components of the Distributor Ignition System using the procedure listed below. If the distributor base has to be replaced, the vent screens will also have to be removed on the new distributor. If there is evidence of this internal corrosion, replace the affected component. Refer to the appropriate procedure in the Engine Controls sub-section of the applicable Service Manual.

 

Important: All of these inspections can be done on-vehicle.

 

 

  1. 1. Inspect the distributor cap. You may notice a white residue on the cap walls. For higher mileage occurrences, the interior of the cap may have changed to medium brown in color
  2. 2. Inspect the distributor rotor. You may notice the presence of black streaks on the plastic surface. More typical evidence would be visible green spots on the copper surface of the rotor segment.
  3. 3. Inspect the distributor base. You may notice high levels of surface rust on the distributor shaft or surface contamination on the sensor hold down screws.
    1580849.gif
    tif.gif
  4. 4. Inspect the distributor vent screens (1). If the vent screens are present, remove them by using a plastic-handled, long blade awl or pick (2). Insert into the airflow vent screens and pop them out. Refer to the figure for removal procedure. If the vent screens have been removed from the base of the distributor, then check the airflow inlets for being clogged with debris.

with 4.3L V-6 Engine (VINs W, X - RPOs L35, LU3)

 

 

Condition

Some owners may comment on a rough running condition or a Service Engine Soon (SES) light being illuminated. Upon investigation, the technician may find a DTC code P0300 or P0335.

 

Cause

The crankshaft sensor may be contacting the reluctor wheel.

 

Correction

Remove the crankshaft sensor. Refer to the Crankshaft Position Sensor Replacement procedure in the Engine Controls-4.3L sub-section of the Service Manual. After removing the sensor, inspect the end of it for witness marks that would indicate contact with the crankshaft. If contact with the reluctor ring is indicated, then inspect the front cover for cracking or other signs of alignment concerns. If the inspection indicates that the cover is causing mis-alignments, replace the cover. If replacing the cover, then the 0.5mm shim is not needed.

 

If the inspection of the front cover indicates that the cover is not the cause of mis-alignments, then the sensor should be shimmed. Add one shim between the sensor and the front cover. If the concern still exists, then add the second shim. Unless the sensor has been rubbed through the casing or deformed by contact with the crankshaft, it should not be replaced.

 

In either case, the crankshaft relearn procedure should be performed after any repairs.

If you encounter vehicles that exhibit the above conditions, refer to SI for the appropriate DTC(s) set. If no trouble is found, the cause may be due to an ECM ground terminal that has corroded with rust over time. Inspect the main engine wiring harness ground terminal (G103) for this condition.

 

The wire terminal (G103) attaches either to the front or to the rear of the right side cylinder head, depending on the model year of the Full Size Pickup and/or Utility Trucks. If the ECM ground terminal has been found to be corroded, then follow the service procedure outlined in this bulletin to correct the corrosion issue.

Service Information

 

 

 

2000 Chevrolet Chevy C Pickup - 2WD | Escalade, Pickup (Classic), Tahoe (Classic), Yukon Denali (VIN C/K) Service Manual | Document ID: 547423 DTC P0304 Cylinder 4 Misfire Detected Refer to Engine Controls Schematics .

 

Circuit Description

The PCM times the intervals between each pulse of the crankshaft position sensor and compares each time interval with the other 8 to determine when an excessive change in crankshaft speed has occurred. This pulse is generated from a 4X reluctor wheel located on the front of the crankshaft. If the crankshaft speed is less than an expected amount, the PCM will increase the amount of fuel needed to correct the misfire. If the amount of fuel exceeds the calibrated value, the PCM will interpret this as a misfire and set the DTC. The misfire diagnostic is used only to identify a week cylinder needing additional fuel. This diagnostic will only run once per ignition cycle.

 

Conditions for Running the DTC

 

• Engine coolant temperature more than 56°C (132°F).

 

 

• Engine idling for a total of 90 seconds.

 

Conditions for Setting the DTC

 

• Fuel adjustment is more than the calibrated value (internal to PCM).

 

 

• Multiple engine misfires detected.

 

Action Taken When the DTC Sets

 

• The PCM illuminates the malfunction indicator lamp (MIL) on the second consecutive drive trip the diagnostic runs and fails.

 

 

• The PCM records the operating conditions at the time the diagnostic fails. The first time the diagnostic fails, the Failure Records store this information. If the diagnostic reports a failure on the second consecutive drive trip, the Freeze Frame records the operating conditions at the time of failure and updates the Failure Records.

 

Conditions for Clearing the MIL/DTC

 

• The PCM will turn off the MIL after three consecutive trips without a fault condition.

 

 

• A History DTC clears after forty consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.

 

 

• The use of a scan tool.

 

Diagnostic Aids

The most likely cause for this DTC is the following:

 

 

• A mechanical failure causing low cylinder compression

 

 

• A fuel leak at the high pressure fuel injection lines or injection nozzles

 

 

• A fuel injection nozzle stuck closed

 

If an injection nozzle is suspected, it can be transferred to another cylinder to determine if the DTC follows the nozzle.

 

After the repair has been performed, it may take approximately 30 seconds for the vehicle to return to a stable idle.

 

Test Description

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

 

 

  1. This step will help identify a suspected cylinder.
  2. This step will identify an area with the most likely cause of failure.
