The importance of repairing this issue lies in the fact that it affects the engine’s performance and fuel efficiency.
The repair difficulty is moderate, and it takes around 1.0 hour to fix.
To interpret the fault code, you need to check the possible causes listed above and visually inspect the related wiring harness and connectors.
| Repair Importance Level | 10.0 (Out of 10) |
| Estimated Repair Time | Approximately 1.0 hour |
| Repair Difficulty Level | 6.67 (Out of 10) |
P2628: Signs Of A Faulty Fuel Injector Circuit
If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of p2628 fault code.
Here are the symptoms to look out for:
- The P2628 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
- Other symptoms may include a decrease in engine power, reduced fuel efficiency, and rough idling.
- Additionally, the vehicle may experience stalling or hesitation during acceleration, and there may be a noticeable decrease in overall performance.
- It is important to address these symptoms promptly to prevent further damage to the vehicle.
P2628: Uncovering The Culprits Behind The Fault Code
The automobile fault code P2628 can be caused by a faulty HO2S, open or shorted HO2S harness, or poor electrical connection.
- The automobile fault code P2628 can be caused by a faulty Heated Oxygen Sensor (HO2S).
- It can also be caused by an open or shorted Heated Oxygen Sensor (HO2S) harness.
- Additionally, a poor electrical connection in the Heated Oxygen Sensor (HO2S) circuit can also trigger this fault code.

P2628: Affordable Fix For Complex Automobiles
The automobile fault code P2628 can be diagnosed and fixed within an estimated repair time of 1.0 hour.
The cost of repair is influenced by the hourly rate charged by the auto repair shop, which typically ranges between $75 and $150 per hour. Therefore, the total cost of diagnosis and fixing the P2628 fault code will depend on the hourly rate charged by the auto repair shop and the estimated repair time required to fix the issue.
P2628: Fuel Injector Circuit Low – Causes And Fixes
The P2628 code is related to the Universal Heated Oxygen Sensor (HO2S) connector. A resistor is installed in the connector to account for part to part variance. The Powertrain Control Module (PCM) determines the value of this resistor by taking multiple measurements during each ignition ON event.
If the PCM determines the resistance value is too high, the test fails and the P2628 code is triggered.
This code specifically refers to the Oxygen Sensor Pumping Current Trim Circuit being high in Bank 1 Sensor 1.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P2628 fault code. This code is usually caused by a faulty Heated Oxygen Sensor (HO2S), an open or shorted HO2S harness, or a poor electrical connection in the HO2S circuit. To fix this issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
