P0732 p1167 p01529 p1166 p0174 p0171. I just put the two o2 sensors in. And fuel pump and alternator. I know I need a intake hose cause it has holes in it. My transmission fluid is low and and burnt the mechanic said .I just put some in there a couple days ago. I know its leaking from a line but the mechanic told me it was leaking from a lot of places. So my question is do I need to get my transmission rebuilt? Which I am not doing just bought the car. And my next question is since I replaced the o2 sensors could all the other codes be old? Please help I don't know what to do.

Vehicle: 2002 Hyundai Santa few v6 2 wheel Dr.

P0732 Gear ratio error 2nd gear

P1167 -02 sensor system Lamba controller at limit (Bank 2)

P1166 -02 sensor systelm Lamba controller at limit (Bank 1)

P0174 Fuel trim lean Bank 2

P0171 Fuel trim lean Bank 1

If the intake has hole in it you may not have fix anything, What vacuum leaks or false air is , anything that gets past the MAF (Mass airflow) and is unaccounted for. P1167 and P1166 mean the 02 sensor reach it maximum ability to manage fuel trim. and as a result you would have a lean fuel trim P0171 or P0174 this is due intake hose having holes in it. Your best bet is to clear the code. fix as much transmission leak as possible from the transmission line . clear the code and fill the transmission at its proper level and proper type of transmision fluid. If P0732 comes back on with the transmission fluid properly filled, you would need a transmission.
