P242B-EXHAUST GAS TEMP SENSOR CIRCUIT PERFORMANCE - BANK 1 SENSOR 3 - DIESEL

If the sensor does not show that the temp is getting up there after you start it, the ECM throws out this code; as far as I know.

Cycle the key three times without starting it. Then disconnect both battries and let it sit for about 15 minutes. Then reconnect batteries and start. See if it comes back. If the light comes on and you get the same code, you got to take it to the stealership!

Hope others provide any information that they might have.

My truck runs fine when the code shows up. And if i just keep clearing it with the edge will my truck go into limp mode or be fine. And i put resistors in the sensors to fool it. Do i need to put differnt ones in there to fix it.

MODELS:
2007 - **2009** (DH/D1) Ram Truck (2500 / 3500 Pickup)
NOTE: This bulletin applies to vehicles equipped with a Cummins 6.7L engine (sale
code ETJ) built on or before **November 27th, 2008** (MDH 1127XX).
NUMBER: 18-013-08 REV. A
GROUP: Vehicle Performance
DATE: December 4, 2008
SYMPTOM/CONDITION:
NOTE: The following conditions and improvements have been addressed with the
latest Engine Control Module (ECM) software. This Service Bulletin (SB) only
addresses the labor associated with the reprogramming of the ECM, the
CCN, and the installation of a Documentation Kit. Any other labor associated
with the performance of additional diagnostics is not addressed by this SB
and must be claimed separately.
A. ISSUES ADDRESSED BY VARIOUS ECM SOFTWARE RELEASES TO DATE:
NOTE: With this latest ECM software release listed in this Service Bulletin, the
following symptoms have been completely addressed.
1. One of the following driveability conditions:
a. An intermittent rough engine idle and/or white smoke following initial engine start.
b. A throttle tip-in stumble at engine speeds of 1,300 to 2,100 RPM.
c. An engine hesitation at altitude of 5,000 feet between engine speeds of 1,200 to
1,600 RPM.
d. A turbocharger “chuff-like” sound during rapid deceleration.
2. The vehicle may fail an Emission Inspection Maintenance (I/M) Test because two or
more On-Board Diagnostic (OBD) monitors report that they are not ready for testing.
This condition may cause the customer vehicle to not pass an Emissions I/M test. The
following is a list of OBD Monitors that may report as not ready for testing:
a. Non-Methane Hydrocarbon (NMHC) Catalyst Monitor.
b. Nitrogen Oxide (NOx) Absorber Monitor.
c. Exhaust Gas Temperature Sensor Monitor.
d. Electrical Charging System Monitor.
e. EGR System Monitor.
f. Oxygen Sensor Monitor.
3. Malfunction Indicator Lamp (MIL) due to one or more of the following Diagnostic
Trouble Codes (DTC's):
a. P0101 - Mass Air Flow (MAF) Sensor Rationality
b. P0128 - Thermostat Rationality
c. U1421 - Implausible Ignition Key Off Time Received
If condition persists perform the appropriate Diagnostic Procedure.
B. ISSUES IMPROVED SIGNIFICANTLY BY VARIOUS ECM SOFTWARE RELEASES
TO DATE:
NOTE: The following symptoms and conditions have been significantly enhanced by
the latest ECM software listed in this Service Bulletin. Always check
TechCONNECT to see if there are new or additional Service Bulletins that
may apply to a condition.
1. The latest ECM software includes a new extended idle feature to accommodate the
extended idle times present in some duty cycles. This feature may help to reduce the
accumulation of soot in the exhaust aftertreatment system when the engine is idling for
an extended period of time. Briefly how this feature works:
18-013-08 REV. A -2-
a. As needed, the engine enters an idling mode which dramatically reduces the rate of
soot accumulation in the diesel particulate filter (called “Net Zero”). Further, under
extended idle periods of **5 minutes or longer**, the engine enters a mode which
reduces the amount of soot accumulated in the diesel particulate filter (called “Net
Reduction”). While in these modes, the idle speed increases to 900 RPM for a
period of time. The idle speed may return to normal idle speed and then return to
900 RPM to repeat this cycle during very long idle periods.
b. **These modes occur automatically depending on the need to regenerate the DPF
as long as the vehicle is not driven over 20 MPH or operated at high load. If the
vehicle is driven over 20 MPH normal mobile desoot will occur automatically.**
2. A MIL illumination due to one of the following DTC's:
a. P2000 - NOx Absorber Efficiency Below Threshold - Bank 1
b. P2A00 - Oxygen Sensor 1/1 Circuit Performance
c. P2A01 - Oxygen Sensor 1/2 Circuit Performance
**If DTC(s) P2000, P2A00 or P2A01 are present, ensure Service Bulletin (SB) 18-035-08
has been completed prior to proceeding with this bulletin. If SB 18-035-08 has been
previously performed, remove and clean both oxygen sensors. Make certain to
thoroughly CLEAN BOTH OXYGEN SENSORS using a clean cloth and compressed
air. Do not use any type of liquid cleaner to clean the oxygen sensor tips.**
3. After extended idling or if an intake leak is present, the vehicle operator may
experience a MIL illumination and/or an Electronic Vehicle Information Center (EVIC)
message alert due to one or more of the following DTC's:
a. P1451 - Diesel Particulate Filter System Performance.
b. P2463 - Diesel Particulate Filter - Soot Accumulation.
c. P242F - Diesel Particulate Filter Restriction - Ash Accumulation.
4. A MIL illumination due to the following DTC:
a. P2262 - Turbocharger Boost Pressure Not Detected - Mechanical
Perform this Service Bulletin, inspect for excessive soot and perform Service
Bulletin (SB) 11-002-08 if necessary. **It is VERY IMPORTANT that SB 11-002-08 be
performed COMPLETELY to return the engine and exhaust aftertreatment systems
to a “like new” condition as necessary.**
5. A MIL illumination due to one of the following DTC's:
a. P200C - Diesel Particulate Filter Over Temperature - Bank 1
b. P242B - Exhaust Gas Temperature Sensor Circuit Performance - Bank 1 Sensor 3.

alright, i am not sure what all of that means ...

Last night, we went and got 330ohm resistors from Radio Shack, as we had 680ohm in the back 2 sensors, and the front one was still in the exhaust, but we went ahead and unplugged that sensor as well and stuck a resistor in there to make it think that it is running hotter in all 3... and on the pressure box we plugged it back in and put a hose and connected both connectors that originally went to the exhaust, but 1985 was saying when he got home that the over head was reading catalyist full, so i told him to just pull the hose off.. SHould he leave the pressure box plugged in and the hose connectors open, or just unplug it...

What is going to put his truck in limp mode.....
like as far as the pressure box....
