What P2673 means
This code says the engine controller holds no valid learned value for the start of delivery of its injection pump. Such a value is usually taught after the pump or the controller is replaced, or after a software reflash, and lets the controller correct the pump's individual timing tolerance. The same Dodge campaign (T21, new engine software for 2004–2006 Sprinter vans) also lists P2673 beside P2672; no public maker document explains its logic. CARB asks for tolerance compensation to be monitored on parts that are matched to the controller. Unlike P2672 the timing itself need not be wrong; the learning step is simply missing. A relearn with a scan tool is the usual cure.
P2673 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 1.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P2673
- Check engine light on
- Slightly rough running or more noise
Common causes of P2673
- Most likelyTiming relearn skipped after pump or controller replacement
- PossibleSoftware update interrupted or learned values lost
- Less likelyRelearn aborted because enable conditions (temperature, voltage) were not met
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2673 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 6 | Area: computer (engine control module) and output circuits. |
| 73 | The exact fault in that area. |
What to do next
- Note P2673 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2673
What does P2673 mean?
P2673 means "Injection Pump Timing Calibration Not Learned". This code says the engine controller holds no valid learned value for the start of delivery of its injection pump. It is a generic code, so it means the same on every make.
Is it safe to drive with P2673?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P2673 fail an emissions test?
Yes, it can. P2673 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2673 to fix?
Difficulty: medium. A typical repair takes 0.5 to 1.5 hours of work. This is a job for a workshop.
Will P2673 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
