Hi,

I own Ex 04 early build, I have multiple codes and i wonder if you can advise how safe it is to drive while these codes exist until i fix them:

Code: P0198 - Engine Oil Temperature Sensor Circuit High Input
Code: P0403 - EGR valve position control circuit
Code: P0405 - EGR Sensor A Circuit Low
Code: P1000 - On-Board Diagnostic (OBD) Systems Readiness Test Not Complete
Code: P2287 - Injector Control Pressure Sensor Circuit Intermittent
Code: B1352 - Ignition key in circuit fault
Code: U1262 - SCP Data Link Fault

P2287 - I replaced the the ICP but it didn't fix the code so I'm planning to replace the pig tail. The impact that i have noticed is while the engine oil is not cold (maybe above 190), the IPR on idle shows 30%, the ICP voltage keeps fluctuating and the ICP bumps from normal idle ~630 psi to ~830. When the trucks cool, i can reset the code and it won't come back until the engine gets hot. During this time the IPR on idle shows 25% which is fine.

P0198 - Fairly new, I ordered the sensor

B1352 -Comes and goes, i have not looked into that yet

P0403 & P0405 - Started when the EGR deleted ~ 8 years ago. I have SCT X4 and i turned the EGR off but the codes never stopped.

U1262- All the testing I have been running based on posts here were completed successfully, i don't have any issues reading any modules.

I was recently driving from NC to TX towing with the these codes besides P0198, and had no trouble.


Can you please advise if i can drive safely until it is fixed or should i not drive at all


Thanks in advanced
