Need component $01 identification for mode 6 module $D1 tests $11, $19, $1A? on 1999 Dodge Ram 1500

Hi, I am troubleshooting my 1999 Dodge Ram 1500 4x4 with 5.9 L & auto trans. My Innova 3160 scan tool shows the following special test results: $11 low, $19 high, $1A high for component $01. All other tests are ok. No present codes, and all monitors have run and set, but the cat monitor took a long time. Fuel economy is not very good,the IAC valve needs to be replaced as it hisses on acceleration. a slight rough idle during warm-up, but runs well other than that. Plugs, wires, rotor, TPS, and oxygen sensors have been replaced within the past 10,000 miles. Can you help me identify which component is identified as $01 in the tests? All help is appreciated!

It is best to go to the manufacturer's technical web site and look under the technical sections for the translations of the hexadecimal values for your specific vehicle. Dodge may charge you for this info, I don't have it, as I would have to pay to log in as well.
If your car passed all the monitors, then you are good to go. If your idle air valve is defective and your are sure of that, then by all means, replace it.
As for your fuel economy, look at your fuel trim. Is it rich or lean? When you say bad fuel economy, could you be more specific? How many miles on your vehicle? I would check to make sure your timing chain is not too stretched, as retarded timing will kill your mileage BIG TIME! Do a base line timing inspection. It can be done even though your 5.9 has its timing controlled by the computer.

Feel free to ask more questions.

Dan: Thank You for the feed back! I checked the manufacturer tech web site as advised, and concluded that the three tests are for the oxygen sensors as follows: ($11 value low bank 1/sensor 1 half cycle counter),($1A value high bank 1/sensor 2 heater trend counter / time to reach voltage), ($19 value high O2 heater bank 1/sensor 1 hot trend counter / time to reach voltage). I would appreciate all input as to the cause and solution, as they are fairly new and the old ones gave the same values!
