Citroën Engine ECU Fault – Causing P2669 & P2670
The EDC17C60s, fitted to various 1.6L diesel Citroëns, are known to carry a fault. When failure strikes, your vehicle won’t start, you’ll see a number of concerning warning lights and the fault codes P2669 and P2670 will store.
This malfunction predominantly affects vans with the DV6FE engine, like the facelifted Berlingo B9 and the Dispatch K0. Although cars like the pre-facelift C4 Cactus and the second-generation C4 Picasso are commonly affected too.

While this fault prompts a range of symptoms – like an engine warning light, an ‘ECU internal fault’ message on the dash, and even a no-start condition – a reliable way of identifying this malfunction is the presence of these fault codes in your Citroën:
- P2669 – Sensors 2 5V electrical power supply. Voltage too low.
- P2670 – Sensors 2 5V electrical power supply. Voltage out of tolerance.
What causes the Citroën to store codes P2669 & P2670?
These codes relate to issues with the 5V supply voltage delivered from the EDC17C60.
Internal failures within the Citroën’s engine control module stop it from operating as intended – hence the starting issues. Under normal conditions, the engine ECU should output a stable 5V reference voltage which is relied upon by multiple sensors to operate correctly.
However, the internal defect in the EDC17C60 is disrupting this process and preventing a normal voltage from being maintained. Therefore, the ECU detects unexpected values in the circuit and flags it in the form of fault codes.
The P2669 (voltage too low) code is stored by the Citroën ECU when it detects little or no voltage in a circuit where it expects one.
The P2670 (voltage out of tolerance) Citroën code is triggered when the ECU detects an unstable voltage in the supply circuit, which falls outside of predetermined parameters.
In the case of this malfunction, these codes are closely linked. When the supply voltage is low, it’s also out of tolerance, and so the Citroen ECU stores both P2669 and P2670.
How to resolve Citroën codes P2669 & P2670
The best way to remedy these running issues and your stored P2669 and P2670 fault codes, is to have your Citroën engine ECU comprehensively rebuilt.
Thankfully, we provide this very service. Our talented team of technicians are experts at rebuilding these tricky control modules so that the defect is not only resolved but also prevented from returning.
We always rebuild with higher-than-OEM-standard components with long-term durability in mind, ensuring your Citroën’s P2669 and P2670 codes are gone for good. Although you won’t need it, we’ll even cover you with an unlimited-mile lifetime warranty too.
Our bespoke service is more effective than sourcing a brand-new or second-hand ECU, as replacement modules remain susceptible to the original malfunction. Our rebuilds even cost less than a replacement and come with longer warranty.

Common failure symptoms:
- No engine start
- Engine cutting out
- P2669 and P2670 codes stored in the Citroën
- ‘ECU internal fault’ message on the dash
- Engine management light on
Common fault codes:
- P2669 - Sensors 2 5V electrical power supply. Voltage too low.
- P2670 - Sensors 2 5V electrical power supply. Voltage out of tolerance.
These engine ECUs are also known to store the codes P1631 and P1632 – find out more here.
Test and rebuild:
We test ECUs on state-of-the-art testing rigs. This allows us to analyse your fault symptoms whilst simulating real-world driving conditions to confirm whether a defect is present. We’ll then confirm whether you wish to go ahead with the rebuild, and if you do, we’ll waive the testing fee.
Programming:
Once your control module has been comprehensively rebuilt, you won’t even need to recode it back to your vehicle either. All coding information previously stored in your module when you sent it to us is retained throughout our process.
Quality:
Long-lasting quality is always the priority of our work, which is why we only use top-grade components and cover you with lifetime warranty. Thanks to a company-wide commitment to continuous improvement and the very latest state-of-the-art remanufacturing equipment, our defect rate is currently as low as 0.49%.
Warranty:
Lifetime unlimited mileage*
