LM7, L59 or L33 Engines with Cold Start Rough or Incorrect Idle, Misfire, Malfunction Indicator Lamp (MIL) or Flashing Requiring O2 Sensor Replacement

2004-2005 Cadillac Escalade 2004-2005 Chevrolet Avalanche, Silverado 1500, Suburban, Tahoe 2005 Chevrolet Silverado Hybrid (HP2) 2004-2005 GMC Sierra 1500, Yukon, Yukon XL 2005 GMC Sierra Hybrid (PH2) with Vortec 5300 5.3L V-8 Engine (VINs T, Z, B — RPOs LM7, L59, L33 Some customers may comment on a Malfunction Indicator Lamp (MIL) On or that the MIL is flashing. An actual engine misfire may or may not be felt along with an incorrect idle speed. Typically this occurs during cold winter months, on cold engine starts. Some vehicles may have been previously serviced for the same condition. Technicians may also find the following DTCs stored with the Tech 2® P0131, P0133, P0134, P0137, P0138, P0140, P0151, P0153, P0154, P0157, P1133, which may be in conjunction with P0171, P0174, P0300 and P1138. Cause Water shock occurs when water droplets are present in the exhaust. The water in the exhaust contacts the sensor element inside the HO2 sensor, causing the HO2 sensor element to crack. Correction Upon diagnostic investigation, the technician may find that the HO2 sensor requires replacement. In addition to replacing the affected HO2 sensor, these vehicles should also be reflashed with the latest PCM calibration. An updated PCM calibration will be available to dealerships as part of TIS 2000 incremental satellite update 11.0 (NAO version 25.010) or greater. Always, make sure your Tech 2 is updated with the latest software version

2005 Nissan Quest Malfunction Indicator Light (MIL) is ON

1 Check scan data for fuel trims to see if the system is in proper fuel control – look for 0% plus or minus 10% in generic or 90 – 110 % alpha in manufacture specific. 2. Verify there are no exhaust leaks. 3. Drive the vehicle and check the bank 1 rear O2 sensor activity on the scan tool or with a voltmeter to see if the bank 1 rear O2 sensor is cross counting like a typical front O2 sensor would. Potential Causes: Catalytic Converter Tech Tips: If in manufacture specific with the scan tool, Nissan displays fuel trims in alpha. 100% alpha is the same as 0% fuel trim. This vehicle has front air fuel ratio sensors – not O2 sensors. Bank 1 is the firewall bank. Bank 2 is the radiator bank. Before the catalytic converter lights off, the rear O2 sensor voltage is usually down around 0.2 – 0.4 volts or so but when the catalytic converter lights off, it uses up a lot of the oxygen so the rear O2 sensor voltage will typically reads around 0.6 – 0.7 volts and have some movement but not a lot of movement and should not cross count above and below 0.5 volts. The catalytic converter is covered under the 8 year 80,000 mile federal emissions warranty.
