OBD Code 101

Showing 7 out of 7 Posts
Question From mwhis2 on OBD Code 101

I have a 2000 Cadillac DeVille, I have replaced the mass air flow sensor, the rubber boot between the throttle body and intake and changed the fuel filter, but I still get a PO 101 trouble code.....anyone have any clues as to what is causing this code????

Response From Discretesignals

HT is right that other problems can cause that to show up. The engine computer is expecting a certain reading from the MAF sensor and it isn't within range of what the PCM thinks it should be. It is a performance code, so unlikely to be a wiring or circuit issue.

How does the engine run? You would really need to look at scan data to see what everything is doing and how the puter is calculating for MAF data.

Response From mwhis2

The car runs fine, we just got back form a 4oo + mile day trip...

Response From Double J Top Rated Answer

Probably out of your league as DS stated.
You will need a scan tool.

There is a TSB out for this concern.
If all checks out, then a reprogram of the PCM may need to be performed.


Subject:Check Engine Light Concern - DTC P0101 Set (Reprogram PCM) #01-06-04-002a - (02/14/2003) Models:2000 Cadillac DeVille, Eldorado, Seville
with 4.6 L Engine (VINs 9, Y -- RPOs L37, LD8)

This bulletin is being revised to update the programming information. Please discard Corporate Bulletin Number 01-06-04-002 (Section 06 -- Engine). Condition
Some customers may comment on a check engine light concern or repeat concern of PCM DTC P0101 code only, with no driveability concerns. If a PCM DTC P0101 light sets but diagnostics provide no indication of component malfunction, a PCM calibration enhancement has been released to correct this concern. This enhancement will correct the setting of the following PCM DTC code:
DTC
DTC Description
P0101
Mass Air Flow (MAF) Sensor Performance Correction
If a vehicle is encountered with the condition described above and all of the diagnostic procedures listed in the applicable Service Manual have been performed with no resulting correction, use a Tech 2 scan tool to verify which software calibration is programmed into the vehicle's PCM. If the improved calibration has not been installed, re-flash the PCM with the updated calibration released on TIS 2000 CD #4 during the week of March 6, 2000 or later.
Important The following procedure MUST BE followed when programming a PCM on a 2000 Cadillac DeVille or Seville. If this procedure is not followed, a system interruption may occur during the programming process causing the PCM to lock-up and not program properly.
To avoid this condition, program the PCM on these vehicles using one of the following methods:
First, verify that the battery voltage is 12.5 volts or higher. If not, charge the battery. DO NOT program the PCM while charging the battery.
Method 1: Program the PCM Off-Board, using the Off-Board Programming Adapter (Kent-Moore J-41207C Off-Board Programming Adapter Kit).
Method 2: Program the PCM On-Board
Caution! It is critical that all J-45211 connections to the PCM, the Tech 2, and the power cable clips stay firmly connected throughout the entire programming procedure. Failure to follow these instructions may cause interruption of the PCM programming, which may result in PERMANENT DAMAGE to the PCM.

  1. Check to ensure that both the Techline terminal and the Tech 2 are updated with their latest respective software.
  2. Turn the vehicle ignition "OFF" and remove the key from the ignition lock cylinder. Turn off all electrical power consumers and accessories.
  3. Open the hood and check the battery voltage directly at the battery positive and negative terminals using J-39200 Digital Multimeter. If the negative battery terminal is inaccessible, or the battery is not located underhood, check the voltage between engine block ground and the underhood "+" junction block.
  4. If the vehicle's battery voltage is not 12.0 volts or higher, charge the battery before continuing. When finished charging the battery, disconnect the charger from the battery before programming PCM.
  5. Locate the PCM and disconnect the vehicle harness connectors from the PCM.
  6. Connect the J-45211 harness connectors to the PCM.
  7. Connect the J-45211 power clips directly to the vehicle battery terminals. If the battery terminals are inaccessible, or the battery is not located underhood, then connect to the engine block (ground), and to the underhood source of "B+" 12-volt power .
  8. Observe the red battery LED on J-45211. The red LED should remain lit whenever the J-45211 is connected to battery voltage. If the red LED does not illuminate, check the tool's 5-amp fuse. If the fuse is okay and yet the red LED will not illuminate, contact Kent-Moore at 1-800-GM-TOOLS for assistance.
  9. Toggle the power switch on J-45211 to apply ignition voltage to the PCM.
  10. The yellow and green LED(s) should illuminate when the power switch is toggled on. The yellow LED monitors the ignition voltage being applied to the control module. The green LED(s) are a feedback signal from the control module indicating that the module's internal circuits are operating.
  11. Connect the Tech 2 to J-45211 and enter Service Programming Systems (SPS)
  12. Select and perform Request Information .
  13. After the Tech 2 has completed the Information Request, toggle the J-45211 switch off.
  14. Turn off the Tech 2 and disconnect it from J-45211.
  15. Connect the Tech 2 to the Techline terminal. Download the new PCM calibration into the Tech 2 using the Techline Terminal and TIS 2000 software. After the download into the Tech 2 is complete, disconnect the Tech 2 from the Techline terminal.
  16. Reconnect Tech 2 to J-45211 and toggle the tool's power switch on.
  17. Enter Service Programming System (SPS) , select and perform Program .
  18. After programming is complete, toggle the J-45211 switch off, and wait until the green LED(s) turn off before continuing or disconnecting any connectors.
  19. Turn off Tech 2 and disconnect it from the J-45211.
  20. Disconnect J-45211 from the PCM, ground and power.
  21. Reconnect the vehicle harness connectors to the PCM and reinstall PCM.
  22. Connect the Tech 2 to the underdash DLC connector, and start the engine.
  23. Turn the Tech 2 on, "build the vehicle", and select Diagnostic Circuit Check . then Clear All DTCs . NOTE: this will clear all DTCs in all control modules, all at the same time.
  24. If the Service Engine Soon light comes back on after clearing DTCs, another concern may be present or a Crankshaft Position Variation Relearn Procedure may need to be performed. Follow existing Service Manual procedures.

If an interruption occurs during the programming process, an error message will be displayed. DO NOT disconnect or shut off power. Re-start the programming process and attempt to program again. In some instances (especially where less than 10% of the programming has been completed), the PCM will lock up and no longer program. If this occurs, the PCM must be replaced.
Important All DTCs, calibration numbers, technician observations and customer comments are to be recorded on the repair order in accordance with article 1.6.2 G of the General Motors Service Policies and Procedures Manual. Calibration Information
The calibrations listed are electronic calibrations and are NOT available from GMSPO. Calibrations are available from Techline on TIS 2000 CD #4 beginning the week of March 6, 2000.

THANKS so much for all of the info. I will be taking it to the shop...Thanks again !!

Response From Discretesignals

There are no other codes popping up, right?

Your going to need a scan tool to look at scan data. TPS voltage, MAP voltage, etc. Anything that affects the air flow through the MAF is all suspect. I'd look at freeze frame data and see how the code is setting. This might be out of your league unless you see something obvious.

Response From Hammer Time

The sensor isn't the only possibility. A problem with the wiring or the PCM itself can also set that code. Even a plugged exhaust could set it.
