DENSO ECU
DENSO 4MB DTC removal
RemoveDTC deletes fault codes (DTCs) from the original file read out of a DENSO 4MB engine ECU. Upload the read, tell us which codes are bothering you, and get the cleaned file back ready to write. Denso ECUs, including the SH7058/SH7059/SH72543 platform and the newer SkyActiv-G/SkyActiv-D families used in Mazda and other Japanese-market vehicles.
What we remove from a DENSO 4MB file
- DPF / FAP pressure and regeneration codes
- EGR valve and flow codes
- AdBlue / SCR / NOx sensor codes
- Lambda (O2) sensor and catalyst efficiency codes
- Swirl flap, throttle body and intake codes
- Any other specific DTC you name in the order notes
Only the codes are removed — the rest of the calibration in your DENSO 4MB file is left untouched.
How it works
- Read the full file from the DENSO 4MB with your usual tool (OBD or bench/boot).
- Upload it — the ECU field is pre-filled with DENSO 4MB — and list the DTCs to remove.
- A technician edits the file by hand and you get an email when it's ready to download and write back.
1 credit = 1 file, from €15.00 excl. VAT. See credit packs.
