This bulletin provides information on tools available to find an intake vacuum leak or exhaust leak to correct a condition of MIL Illuminated with Multiple Fuel Trim and/or Oxygen Sensor Codes Set.
Some customers may comment that the MIL is illuminated.
Technicians may find one or more of the following conditions:
Note: Initial diagnosis may display any of these fuel trim and/or O2 sensor related codes.
If normal SI diagnostics does not lead to a resolution and an intake vacuum leak or an exhaust leak is suspected, the GE-52250 Variable Pressure Leak Detector (preferred method), the J-41416 ultrasonic leak tester, or possibly using soapy water and low pressure air into the tailpipe, may be useful to find the leak.
Note: All of these tests are much more effective if the throttle body is covered/sealed.
For an intake leak, the smoke can be introduced into the brake booster hose or the oil dipstick tube. Soapy water can be sprayed near the gasket and seams and all vacuum nipples.
For an exhaust leak, the hose into the tailpipe with smoke or air sealed with shop towels proves to be effective. Then soapy water would be sprayed around seal, seams and bosses. Ultrasonic leak detector may also find leaks in this way.
These methods are very good for finding small leaks around the O2 sensor embossments and slight cracks in an intake plenum or gasket.
This process was also recommended in the 10207.07D – July 2007 Emerging Issues training seminar (U.S.).
