21126 Multiple Vehicle Line MAF Sensor Service Tip

For 1997-2010MY gas engine vehicles exhibiting diagnostic trouble codes P0171-P0175, lack of power, hesitation, rough running, or surge drivability concerns due to contaminated Mass Airflow Sensors (MAF). If normal diagnostics lead to the MAF sensor, inspect the sensor hotwire for contamination. Clean the sensor with CRC Mass Air Flow Sensor Cleaner #05110. Do not use shop air or harsh chemicals. This can cause serious damage. CRC MAF Sensor Cleaner will safely clean the MAF hotwire and electrical components. Monitor LongFT1 and LongFT2 PIDs after cleaning to confirm repair.

20680 Gas Engine Coil on Plug (COP) Diagnostic Testing

When diagnosing Coil on Plug (COP) ignition primary circuit malfunction DTCs P035X-P0360, always verify harness integrity using PCED Pinpoint Test JF. In rare instances, COP DTCs can be a result of PCM driver failures. To confirm PCM driver function, use IDS Toolbox Oscilloscope "Escape PCM Driver" test. If missing pulses are observed, follow PCED diagnostics to resolve. Do not replace the PCM if all coil pulses are present.

20677 Gas Engine Multiple Coil Primary Circuit Diagnostics

Diagnostic Trouble Codes (DTC) P0350/P035X-P0360 can only be set by a primary circuit malfunction. A secondary ignition failure will not set these DTCs. If a P0350/P035X-P0360 DTC has been set, the PCM will invoke Failure Mode Effects Management (FMEM), which will shut down the injector for the faulted cylinder. This is normal operation to protect the catalyst. Do not condemn the injector when a P0350/P035X-P0360 DTC is present. A primary circuit malfunction will always set a P0350/P035X-P0360 DTC before a P030X (Cylinder X Misfire Detected). If the cause of the primary circuit malfunction is a short to ground, the ignition coil will be damaged within seconds; however, the PCM will not be damaged. Do not replace the PCM without verifying coil driver functionality.

05-22-08: WDS COP Kit Diagnostic Tips - Coil on Plug (COP) Ignition Systems - Engine Misfire or Rough Running

Approximately 50% of Coil on Plug (COP) coils returned for warranty do not have a problem. The misfiring cylinder must be identified through self-test misfire codes or through WDS Power Balance. Rule out base engine problems, fuel problems, and then look at ignition problems. Be sure to rule out coil primary circuit issues. Once the above steps have been completed, and the issue is in the secondary part of the ignition system, the oscilloscope procedure outlined in this TSB can isolate the difference between a coil or spark plug problem.

05-05-06: Alternative Fuel Vehicle - Compressed Natural Gas Fuel Tank Inspection

Federal law requires guidance for CNG tank inspection. The National Highway Traffic Safety Administration (NHTSA) has mandated that natural gas fuel tanks for vehicles produced after December 2, 1996, be inspected for damage or deterioration every 36 months, or 36,000 miles, whichever comes first, or after a fire or accident. It is the customer's responsibility to get their CNG fuel containers inspected by 3 years/36,000 miles and to be in compliance with FMVSS requirements and industry standards.

01-21-13: Driveability - Electrical - Sticking or Binding Ignition Lock Cylinder - High Effort When Turning Ignition Switch - Diagnostic Trouble Codes (DTC) P0500, P1502 and/or U1039 on Some Vehicles

Some ignition switch lock cylinder assemblies may exhibit the following highly intermittent conditions: roughness and/or excessive effort in turning the key from RUN to START position. Key does not fully return from START to RUN after starting vehicle. This may result in intermittent accessory function. Continental only - a Malfunction Indicator Lamp may illuminate with diagnostic trouble codes P0500, P1502 and U1039 stored in the Powertrain Control Module's (PCM) memory. This may be caused by a key-in-ignition warning chime switch. Replace the key-in-ignition warning chime switch located on the ignition switch lock cylinder with revised part XL2Z-11A127-AB.
