But if you donвЂ™t know that, you may assume the engine has a misfire problem. ItвЂ™s a programming glitch that OBD II ignores as it monitors misfires. Of course, there are no cylinders 7 and 8 in a V6. The CID test results may show high misfire rates for cylinders 7 and 8. On some Ford V6 applications, Mode $06 will report misfire rates for cylinders that donвЂ™t exist. It allows changes in calibration to be easily updated (assuming you have a J2534 pass-through tool or a scan tool with flash capabilities).ДЄnother thing to watch out for when viewing Mode $06 data are TID/CID tests that contain old data or bogus data. The vehicle manufacturer may revise the limit and offer a new calibration that can be downloaded and loaded into the vehicleвЂ™s PCM.

For example, a vehicle may be setting a misfire code repeatedly because the maximum limit for misfires was set too low. Though OBD II performs a long list of component self-tests, sometimes a test limit may be set too high or too low, causing codes to set unnecessarily.

Repairs so all the OBD II monitors will run and pass. You have to read and clear the code, diagnose the fault and make the required A vehicle cannot pass an OBD II plug-in emissions test if the Check Engine light is on. This includes lean fuel mixture codes, misfire codes and catalyst efficiency codes. In some cases, OBD II may set a fault code for a problem that is being caused by something else. If the test results are just within the limits, it would tell you the sensor is probably causing a problem and will soon fail. ThatвЂ™s why you need to look closely at the CID test results for that sensor in Mode $06 so you can see how close the sensor is operating to its upper and lower limits. It may not be bad enough to fail its CID tests, but it might be sluggish or biased enough to throw off the air/fuel mixture, resulting in a loss of fuel economy, poor throttle response or an engine misfire. If it is near the upper or lower limit of the acceptable test range, it may be enough to cause a noticeable driveability or emissions problem.ДЇor example, say one of the oxygen sensors is lazy or is biased rich or lean. HereвЂ™s another mystery of Mode $06: Even if a sensor is functioning within the established limits for a particular CID test, you canвЂ™t always assume the sensor is functioning normally. The вЂњ$вЂќ symbol means the data is in hex code, not ordinary decimal numbers.

It is tabulated in hexadecimal code (a base 16 number system that uses digits 0 to 9 plus letters A through F), which is the computer language that the PCM uses to manage things. Mode $06 data is information the OBD II system tracks and compiles on вЂњnoncontinuousвЂќ monitors. Mode $06 is often the key to solving no-code driveability and emission faults, to identifying sensors and other components that are still operating within acceptable limits but are on the verge of failure, and for reducing comebacks involving the catalytic converter, EVAP system and EGR system repairs and engine misfires.

In fact, if a technician knows how to use Mode $06 to look for certain kinds of faults, they can usually keep the Check Engine light out and prevent unnecessary comebacks. With that said, itвЂ™s helpful to be aware of Mode $06 and how a technician can use it to troubleshoot a Check Engine light that comes back on after repairs have been made.
