I had codes p0171 p0174 p1000 p2106 come on any help

Question

• its on a 2004 ford f-150

Answer 1

P0171 Fuel trim system lean (Bank 1)

P0174 Fuel trim system lean (Bank 2)

P1000 On board diagnostic readiness not complete

P2106 Throttle actuator control system (forced idle)

P2106 should be diagnosed as a symptom because of the lean bank codes. What causes lean codes are , low fuel pressure, under reporting MAF (mass air flow) , and vacuum leaks ,Look and inspect for vacuum leaks especially the PCV hose and especially the brake booster hose,Also do a MAF cleaning or replace the MAF sensor, P1000 means the codes have been cleared, A faulty MAF sensor can cause P2106.
