lambda sensor p1131 no activity

[SB98UKexplorer]

hi all, i had my car diagnosed before and after my remmap had been done and found the code appeared again after, from there software (gendan) it shows there is no communication from sensors, or no power supply to sensors. do they have fuses or relays to these?

all the heater circuits of the Lamba sensors have a +12v feed from a single fuse (20 Amp) which I think is fuse number 24 on the inside fuse box. so I would recommend checking that fuse first.

Other than that, the sensor and heater control circuits are controlled directly by the PCM (Powertrain Control Module) which gets more complicated....

well it wont go into warp speed as it cant obtain the correct A/F ratio, he bypassed that with the software at the time of remap and re enabled it after, 220hp is roughly where its at now, ill be heading to a dyno station soon i fix this problem

well its fixed, the terminal wire going into the cheese block had broken off, it doesnt have ford plugs to connect the lamndas, just need o ring for dipstick still as im loosing oil at speed lol
