MIL Illuminated with Fuel Trim and Oxygen Sensor Codes
1. 1Fault
  - Customers may comment that the MIL is illuminated.
  - Initial diagnosis may show fuel trim and O2 sensor related codes including P0101, P0137, P0138, P0140, P0141, P0157, P0158, P0160 and P0161.
  - The listed codes also include P0171, P0174, P0420, P0430, P1174 and P1175.
  ↓→
2. 2Finding the cause
  Possible causes
  - These methods find small leaks around the O2 sensor embossments and slight cracks in an intake plenum or gasket.
  Steps to confirm (in the document’s order)
  1. If normal SI diagnostics do not lead to a resolution and an intake vacuum leak or exhaust leak is suspected, use the GE-52250 Variable Pressure Leak Detector (preferred), the J-41416 ultrasonic leak tester, or possibly soapy water with low pressure air into the tailpipe to find the leak.
  2. For an intake leak, introduce the smoke into the brake booster hose or the oil dipstick tube; soapy water can be sprayed near the gasket, seams and all vacuum nipples.
  3. For an exhaust leak, put the hose with smoke or air into the tailpipe sealed with shop towels, then spray soapy water around seals, seams and bosses.
  ↓→
3. 3Correction
  Parts
  - No parts are required for this repair.
  Caution
  - All of these tests are much more effective if the throttle body is covered or sealed.
