Hi My f360 f1 got the "slow down" on and OBD code P1454 for 4 times in this week.. I replaced LH THERMOCOUPLE due to SD3 shown error cames from that... But still "slow down" light on with after 1-2 mins of vehicle start engine in the morning. Any idea???
Make sure the earth to the ecu is good ( I have seen this bring on the slow down light too) Are you sure you changed the correct ecu. At idle left is right & right is left. Can you see parameters at idle ? If cat temp is at 1000 degrees it will prob be the temp probe that goes from the cat to the ecu.
Thanks for reply but how do I proof the earth to the ecu is good ??Could you explanation for this? I didn't changed ecu....changed temp sensor(THERMOCOUPLE) No.19 item in my attachment. The vehicle still with slow down light on but no engine light on.....Any advice?? I'll goto dealership want my vehicle parameters file then show to this thread...
