** SOLUTION **
Cause
To be read prior to replacing any parts. Additional diagnostic instructions
for addressing DTC P2042-01 on US17 emissions level vehicles.
Solution
P2042-01 is an evaluation of the DEF Pump temperature sensor. When
battery voltage is low and both ambient air temperature and DEF tank
temperature are below 32 °F (0 °C), this diagnostic logs a fault, even when
there is no problem with the DEF pump temperature sensor.
If a vehicle has this code logged on a DTC Readout:
- Review the Detailed Status Information for the relevant code on the DTC
Readout.

• If Confirmed DTC is TRUE:
- Proceed with diagnostics for the code in Premium Tech Tool.
- If diagnostic steps in PTT do not determine an external issue (wiring,
power, etc.) and advises to replace the pump: DO NOT REPLACE THE
PUMP.
- Clear the code and release the vehicle.
• If Confirmed DTC is FALSE:
- DO NOT troubleshoot the code.
- If no other codes are present that require diagnosis, clear the DTC and
release the vehicle.
This issue is expected to be addressed in a future software update, and this
solution will be updated when more information is available.
Internal comments
If P2042-01 is confirmed (we have seen very small percentage of trucks
(BO)
logging the code had MIL, <5%), we would like to get P1H6V parameter
logged with our regular panel for 2-3 minutes.
Key ON 15 seconds, start idle for 30 seconds, Key Off 15 seconds
Repeat 2 to 3 times.
Expected to see P1H6V (DEF pump temperature) to read something other
than 419F (default) atleast for few seconds.
Contact NATARAJ BHAT if there is any doubt. DO NOT RECOMMEND DEF
PUMP CHANGE.
