Scanned my car today got a P0700 and a P1166-7

Question

changed solenoid B & C. rescanned it and it came out again. other forums say to change the transmission fluid but idk if its gonna help. can someone help me please?

Answer 1

P0700 Transmission fault detected, Mil light requested

P1166 / 7  A/F heater  circuit malfunction

For the P1166/7  this is wrong application for the  A/F or 02 sensor which is commonly reffered to. That or the 02 sensor is not properly torque down.   With P0700 the reason may tell you to replace the transmission fluid is their concern of whether the transmission fluid is the correct fluid.
