Please help.....
Pulled the two below codes from my car which drives likes its in limp mode.
18339 - Coolant Fan Control Module (J293): Malfunction
P1931 - 004 - No Signal/Communication - Intermittent
17522 - Oxygen (Lambda) Sensor; B1 S2: Internal Resistance too High
P1114 - 008 - Implausible Signal - Intermittent
I've checked both fans and they spin at low speeds thus my water temp was over 100c. I believe the J293 is a possible cause but this part is pretty expensive. I checked both fans could spin freely by hand but noticed the main 600w was squeaking, possibly carbon bushes are worn.
Question is could a faulty fan throw a malfunction code from the J293? If the carbon brushes are worn the fan will sooner or later burn out. The J293 would read this as a faulty module correct?
Not driven the car since and considering to replace the main fan before the J293 fan control module. Other symptoms I have is the A/C not being cool. So do I have a fan that is dying plus a dying J293 module?
Is the second code caused by higher than normal temps from the exhaust gases?
Thanks!
