What P026E means
Some engines cool the charge air with a coolant-to-air cooler in its own low-temperature circuit with an electric pump. P026E means that pump is electrically sound but does not deliver as commanded – judged from feedback by the pump electronics or from the missing temperature drop. FCA documents it on the 2017 Alfa Romeo Giulia and 2018 Stelvio with the 2.0 turbo, together with P024A, and fixed it with a software update; thresholds are not published. Air in the circuit or low coolant lets the pump run dry; hot charge air then costs power.
P026E at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 2.5 hours
- Clears after repairAfter a drive cycle
Symptoms of P026E
- Check engine light on
- Loss of power in heat or under load
- Follow-up code P026A possible
- Level in the auxiliary coolant tank drops
Common causes of P026E
- Most likelyAir in the low-temperature circuit or low coolant (pump runs dry)
- Most likelyPump faulty internally (bearing, impeller, electronics)
- PossibleSoftware or calibration
- Less likelyWeak supply or ground, corroded connector
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P026E means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 2 | Area: fuel and air metering (injector circuit). |
| 6E | The exact fault in that area. |
What to do next
- Note P026E 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 P026E
What does P026E mean?
P026E means "Charge Air Cooler Coolant Pump A Performance". Some engines cool the charge air with a coolant-to-air cooler in its own low-temperature circuit with an electric pump. It is a generic code, so it means the same on every make.
Is it safe to drive with P026E?
Drive gently and only to a workshop. With P026E the car can go into limp mode (reduced power) to protect itself.
Will P026E fail an emissions test?
Yes, it can. P026E 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 P026E to fix?
Difficulty: medium. A typical repair takes 0.5 to 2.5 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P026E 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.
