The vehicle (where a record says)

A record is under an engine, a drive or a series only where it says so: the characters of the vehicle identification number filed with a complaint, its text, or what its document says it applies to. A record that does not say is kept as "not stated". The filed numbers and the documents do not tell 4WD from AWD.

Common on this vehicle:LeakAir conditioning or heaterSmoke or fireWarning light

Record by record

4 records state a cause or a remedy. Each record is shown as short labels in the order fault → finding the cause → correction. Press a label to narrow to the records that state it.

Symptom

Component named as the cause

A ribbon is as wide as the records that state both of its ends (only the commonest are drawn). A record that names several symptoms or components runs through each. Orange is records that say the fault came back or was not fixed. Results come from owners’ reports only; one that does not say is “result not stated”. None of this is a likelihood of a cause or a rate at which work succeeds.

    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.

    Diagnostic Tip: Using Smoke Machine and Ultrasonic Detector for Air Leaks

    1. 1Fault

      • The SES light is on, and initial diagnosis may show fuel trim and/or O2 sensor related codes such as P0171, P0174, P0420 and P0430.

    2. 2Finding the cause

      Steps to confirm (in the document’s order)

      1. If normal SI diagnostics do not resolve it and an intake vacuum leak or exhaust leak is suspected, the J41413-200 Evaporative System Tester smoke machine, the J-41416 ultrasonic leak tester, or soapy water with low pressure air into the tailpipe may help find the leak.
      2. For an intake leak, the smoke can be introduced into the brake booster hose or the oil dipstick tube.
      3. Soapy water can be sprayed near the gasket and seams and on all vacuum nipples.
      4. For an exhaust leak, a hose into the tailpipe carrying smoke or air, sealed with shop towels, is effective.
      5. Then spray soapy water around the seals, seams and bosses.
