What P2407 means
P2407 reports a pump feedback that jumps around instead of staying steady. On current-measuring DMTL pumps VW's 2014 Golf and Touareg books define it precisely: the pump current fluctuates by more than 1 mA during the reference measurement, or it drops by more than 6 mA for at least 3 s while pumping, checked with the engine off and on. Audi's TSB 2071770 (Q5, Q5 e, Q3, Q7 and others, 2022-23) calls the diagnosis too sensitive and cures it with new ECM software, and VW's 01-23-03 does the same for the 2022 Atlas and Atlas Cross Sport 2.0T before any parts are replaced. Maserati and Jaguar list P2407 too. P2404 is the steady implausibility, P2403 a lost signal. The car runs normally; the warning light is the main effect.
P2407 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium
- Typical labor0.5 to 2 hours
- Clears after repairAfter a drive cycle
Symptoms of P2407
- Check engine light, sometimes only after the car has been parked
- Code returns irregularly after clearing
Common causes of P2407
- Most likelyOver-sensitive diagnostic calibration, fixed by ECM software update (Audi, VW 2022-23)
- PossibleLoose contact or corrosion at the pump connector
- PossibleWorn pump motor with unstable current draw
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2407 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 07 | The exact fault in that area. |
What to do next
- Note P2407 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 P2407
What does P2407 mean?
P2407 means "EVAP System Leak Detection Pump Sense Circuit Intermittent/Erratic". P2407 reports a pump feedback that jumps around instead of staying steady. It is a generic code, so it means the same on every make.
Is it safe to drive with P2407?
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 P2407 fail an emissions test?
Yes, it can. P2407 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 P2407 to fix?
Difficulty: medium. A typical repair takes 0.5 to 2 hours of work. This is a job for a workshop.
Will P2407 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.
