Engine Controls - MIL ON/DTC's P0031/P0138/P2195
TECHNICALBulletin No.: 11-06-04-003
Date: February 01, 2011
Subject: Malfunction Indicator Lamp (MIL) Illuminated, DTC P0031, P0138 and/or P2195 Set (Diagnose Heated Oxygen Sensors (HO2S), Reprogram Powertrain Control Module (PCM))
Models:
2009-2010 Pontiac Vibe
Equipped with 1.8L Engine RPO LAY and Transmission RPO MVB or MVE
Attention:
Before proceeding with the reprogramming procedure in this bulletin, the Vibe Programming Application MUST be downloaded and installed on the PC. Refer to Corporate Bulletin Number 09-06-04-006A.
Condition
Some customers may comment that the malfunction indicator lamp (MIL) is illuminated.
A scan tool may reveal the following DTCs set as Current or in History:
- DTC P0031: HO2S Heater Control Circuit Low Voltage Sensor 1
- DTC P0138: HO2S Circuit High Voltage Sensor 2
- DTC P2195: Heated Oxygen Sensor (HO2S) Signal Biased Lean Sensor 1
Cause
This condition may be caused by the HO2S Sensor 1 and/or a calibration anomaly in the software of the PCM.
Correction
Perform the Diagnostic System Check - Vehicle, in order to determine the DTC(s) that is set.
Bulletin Starting Point for DTC P0031: HO2S Heater Control Circuit Low Voltage Sensor 1
DO NOT replace the powertrain control module (PCM) for this condition.
1. Diagnose and determine if the HO2S Sensor 1 is at fault. Refer to DTC P0031, P0032, P0037 or P0038 in SI.
• If diagnosis determines that the HO2S Sensor 1 is at fault, replace the sensor. Refer to Heated Oxygen Sensor Replacement - Sensor 1 in SI.
Proceed to Step 2.
• If diagnosis determines that the HO2S Sensor 1 is not at fault, then this bulletin DOES NOT apply.
2. Reprogram the PCM. Refer to the section for Reprogramming the PCM, in this bulletin.
Bulletin Starting Point for DTC P0138: HO2S Circuit High Voltage Sensor 2
DO NOT replace the powertrain control module (PCM) for this condition.
1. Observe the Freeze Frame/Failure Records data for the HO2S Sensor 1 and HO2S Sensor 2.
• If the HO2S Sensor 1 voltage is between 3.35V and 3.70V AND the HO2S Sensor 2 voltage is between 0.70V and 0.90V, proceed to Step 2.
• If the HO2S Sensor 2 voltage is more than 1.10V and/or the Sensor Impedance is more than 300ohm at operating temperature, then HO2S Sensor 1 is not at fault and this bulletin does not apply.
2. Replace the HO2S Sensor 1. Refer to Heated Oxygen Sensor Replacement - Sensor 1 in SI.
Proceed to Step 3.
3. Reprogram the PCM. Refer to the section for Reprogramming the PCM, in this bulletin.
Bulletin Starting Point for DTC P2195
DO NOT replace the powertrain control module (PCM) for this condition.
1. Diagnose and determine if the HO2S Sensor 1 is at fault. Refer to DTC P2195 or P2196 in SI.
• If the HO2S Sensor 1 circuits are at fault, repair as needed. After repairing the HO2S Sensor 1 circuits, reevaluate the sensor for proper operation.
• If the HO2S Sensor 1 circuits are not at fault, proceed to Step 2.
2. Replace the HO2S Sensor 1. Refer to Heated Oxygen Sensor Replacement - Sensor 1 in SI.
3. Reprogram the PCM. Refer to the section for Reprogramming the PCM, in this bulletin.
Bulletin Starting Point for Both DTC P0138 and P2195 Set Together
DO NOT replace the powertrain control module (PCM) for this condition.
1. Observe the scan tool DTC data.
• If both DTC P0138 and P2195 are set, replace the HO2S Sensor 1. Refer to Heated Oxygen Sensor Replacement - Sensor 1 in SI.
Proceed to Step 2.
2. Reprogram the PCM. Refer to the section for Reprogramming the PCM, in this bulletin.
Reprogramming the PCM
- Use a multiple diagnostic interface (MDI) for reprogramming and ensure that it is updated with the latest software version.
- During programming, the battery voltage must be maintained within the proper range of 12-15 volts. Only use the approved Midtronics(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent during programming.
