What P207F means
P207F: SCR operator inducement active (equivalent SPN 5246 family).
Applies to: PACCAR MX-11, MX-13 with SCR.
Severity: Critical — derate/5-MPH sequence.
Symptoms you'll see
- Red SCR warning
- Torque derate or active countdown
Likely causes (ranked by probability)
- Unresolved DEF quality/level fault
- Unresolved NOx or SCR-efficiency fault (P1495 family) past grace period
- Dosing system failure unaddressed
Diagnostic steps
- Find the originating fault — P1495, P20E8 or DEF-related entries precede P207F.
- Repair per the originating procedure; verify with DAVIE4's aftertreatment test.
- Perform the inducement reset in DAVIE4.
- Road test watching NOx conversion efficiency.
Tools that read, clear and verify this code
DAVIE4 required for the cleanest reset; major CV scanners support post-repair resets. For the full per-platform picture see the PACCAR MX-13 fault codes page and our Aftertreatment derate guide.
Frequently Asked Questions
Can I drive with P207F active?
Severity on this code: Critical — derate/5-MPH sequence. If a derate countdown is armed, use the remaining runtime to reach a shop — not to finish the week. Verify the root cause with the diagnostic steps above rather than clearing and hoping.
Will clearing P207F without repairs work?
The code will return — usually within one drive cycle — and on aftertreatment-related faults the inducement countdown often shortens each time. Repair first, verify with the guided test, then clear.
Which scanner reads P207F?
DAVIE4 required for the cleanest reset; major CV scanners support post-repair resets.
