MULTI-MODEL (WITH SKYACTIV 6AT) - CHECK ENGINE LIGHT AND AUTOMATIC TRANSAXLE WARNING
LIGHT ON WITH DTC P0842, P0847, P0872 AND/OR P0877 STORED IN TCM MEMORY
APPLICABLE MODEL(S)/VINS
2012-2014 Mazda3 (with SKYACTIV 6AT)
2013-2015 CX-5 (with SKYACTIV 6AT)
2014-2015 Mazda6 (with SKYACTIV 6AT)
DESCRIPTION
Some vehicles may experience the check engine light and automatic transaxle warning light ON with DTC
P0842, P0847, P0872 and/or P0877 stored in the TCM memory.
• P0842:00 - Oil pressure switch No. 1 (oil pressure switch B) stuck on
• P0847:00 - Oil pressure switch No. 2 (oil pressure switch A) stuck on
• P0872:00 - Oil pressure switch No. 3 (oil pressure switch A) stuck on
• P0877:00 - Oil pressure switch No. 4 (oil pressure switch B) stuck on
The DTC P0780 and/or P1738 may also be stored together.
• P0780:00 - Gear shifting malfunction
• P1738:00 - Automatic transaxle internal malfunction
This is caused by the oil pressure switch A and/or B at the control valve body temporarily or permanently getting
stuck due to contamination entering the passage. To correct the problem, some mass production changes have
been implemented to reduce contamination and improve the DTC diagnostic logic.
Customers having this concern should have their vehicle repaired using the following repair procedure.
REPAIR PROCEDURE
1. Verify customer concern.
2. Check for DTCs.
• If any of the DTCs (P0842, P0847, P0872, P0877) is stored in TCM memory, go to step 3.
• If any other DTCs are present or no DTCs are present, perform troubleshooting according to Workshop
Manual.
3. Remove the oil pan from the transaxle according to the instructions on MS3 online or the Workshop Manual
(section 05-17 CONTROL VALVE BODY REMOVAL/INSTALLATION [FW6AEL, FWAX-EL]).

13. Install the removed parts.
14. Add ATF according to the instructions on MS3 online or the Workshop Manual (section 05-17 AUTOMATIC
TRANSAXLE FLUID (ATF) REPLACEMENT [FW6A-EL] ).
15. Connect the negative battery cable.
16. Perform the Initial Learning Procedure. Refer to MS3 online instructions or Workshop Manual section 05-17.
17. Perform the Mechanical System Test. Refer to MS3 online instructions or Workshop Manual section 05-17.
18. For 2012-13 Mazda3, reprogram the TCM to the latest version by using Mazda Modular Diagnostic System
(M-MDS) if the vehicle is within the following range.
• VIN Range: JM1BL******500001 - 733727 (through September 28, 2012 production)
• TCM file name: PE08-21-PS1-J or older
a. Reboot the IDS to clear memory before reprogramming.
b. Using IDS 89.03 or later software, reprogram the PCM to the latest calibration (refer to “Calibration Information” table) by following the “Module Reprogramming” procedure.
NOTE:
•
•
•
•
•
•
Always update the IDS tool first, then follow on-screen instructions to download the needed
calibration file for PCM reprogramming.
It is not necessary to remove any fuses or relays during PCM reprogramming when the IDS
screen prompts you to do so. You may accidentally stop power to one of the PCM terminals
and cause the PCM to be blanked, or you may receive error messages during the IDS reprogramming procedure.
IDS shows the calibration part numbers after programming the PCM.
Please be aware that PCM calibration part numbers and file names listed in any Service Bulletin may change due to future releases of IDS software, and additional revisions made to
those calibrations for service related concerns.
When reprogramming a PCM, IDS will always display the “latest” calibration P/N available for
that vehicle. If any calibration has been revised/updated to contain new information for a new
service concern/issue, it will also contain all previously released calibrations.
When performing this procedure, we recommend using the “Power Supply” mode in
the Battery Management System to keep the vehicle battery up to capacity. If a different charger is used, make sure it does not exceed 20 AMPS. If it exceeds 20 AMPS, it
could damage the VCM.

c. After performing the PCM reprogramming procedure, verify the repair by starting the engine and making
sure there are no MIL illumination or abnormal warning lights present. Verify that the TCM file name is
PE08-21-PS1-K or later.
NOTE:
•
•
If any DTCs should remain after performing DTC erase, diagnose the DTCs using MS3 online
instructions or Workshop Manual section 01-02.
After PCM reprogramming, it is no longer necessary to road test the vehicle to “relearn” KAM
(Keep Alive Memory).
19. Verify repair.
