New code today

Anyone help be decipher, Google has not been helpful thus far.

DTC P118B Particulate Matter Sensor Temperature Not Plausible

Circuit/System Description
The particulate matter (PM) sensor monitors the amount of the particulates (soot) in the diesel exhaust gas exiting the tailpipe. The PM sensor is similar to the heated oxygen sensor with a ceramic element, but also includes an individually calibrated sensor control unit (SCU). The sensing element includes comb shaped interdigital electrodes (IDE), a heater and a positive temperature coefficient resistor for temperature measurement. The operation of the PM Sensor is based on the electrical conductivity characteristic of the diesel particulate. As the exhaust gas flows over the sensing element, soot is absorbed in the combs between the electrodes, eventually creating a conductive path. When the path is formed, it generates a current based on the voltage being applied to the element. The measurement process continues until a preset current value is reached. To avoid misleading readings, the sensor performs a regeneration where the soot is cleaned off by heating up the element, before the measurement phase begins. The amount of regenerations is based on vehicle strategy; when the calibrated number of regenerations is reached, the cumulative current readings are used to determine the amount of soot concentration in the exhaust gas which in turn determines the collection efficiency of the diesel particulate filter (DPF).

Conditions for Running the DTCs
DTC P142C, P142D, P142E, P142F, P1474, P1475, P1476, P1477, P1478, P16D7, P16D8, P16D9, P24B0, P24B1, P24B3, P24B5, P24B6, P24D0, or U02A3 is not set. The ignition is ON. The vehicle has had a minimum OFF time of 8 h. The ignition voltage is greater than 11 V. The reductant control module relay 2 is commanded ON. The DTC runs continuously when the above conditions are met.

Conditions for Setting the DTC
The particular matter sensor control unit detects an internal fault of the sensor.

Circuit/System Verification
1. Ignition On. Verify no other DTCs are set⇒ If any other DTCs are set Refer to Diagnostic Trouble Code (DTC) List Vehicle⇓ If no other DTCs are set 2. Verify DTC P118B is not set. ⇒ If the DTC sets Replace the B136 Exhaust Particulate Matter Sensor.⇓ If the DTC does not set 3. All OK

Thanks! Just got to keep on waiting for my parts to come in

I was worried it was something not emission related and I was going to be forced to go into the dealer.

More Emission sensor issues????

Please keep us advised of your findings

My findings will be removing it completely in about a week

 

[mrpositraction]

....... Until then he will be reading and erasing emission sensor codes frequently.

EVERY SINGLE TIME I START IT UP!!!!!!!!!!

Super annoying

Does it do this when returned to stock programming and intake?

Switching it back to "modified stock" tuning on the DSP I still get it. I am not interested in taking the aftermarket intake and hard pipes off to see if it fixes it.

My take is there are problems with the emission systems, too many people with problem not modified. I am not saying my tune/intake is causing this, but it definitely could make it worse. Many have voiced concern over tuning while running emissions, this definitely supports their theories.
