P2200 on Volvo by model: symptoms, diagnosis and fix
On AdBlue/SCR-equipped diesel V60s, faults in the NOx sensors and AdBlue dosing system are common. A drifting or failed NOx sensor makes the system believe the SCR catalyst is not reducing emissions, throwing AdBlue/dosing warnings and limp mode. Critically, persistent NOx/SCR faults trigger an emissions 'start-prevented' countdown that, if ignored, will refuse to restart the engine. Air trapped in the dosing line, a faulty dosing valve/module, or contaminated AdBlue can produce the same symptoms.
Common Symptoms
- AdBlue / emissions warning with no-start countdown
- Limp mode and reduced power
- AdBlue dosing service required message
- NOx sensor circuit fault codes
- Increased AdBlue consumption
How to Fix
Scan for specific NOx/SCR codes (do not rely on the generic AdBlue message). Replace the failed upstream or downstream NOx sensor or the AdBlue dosing module/valve as indicated, prime/bleed air from the dosing system, use only fresh, uncontaminated DEF, and clear the fault and reset the SCR system with a diagnostic tool to cancel the no-start countdown. Verify live sensor data makes sense before returning the car to service.

Frequently asked questions
What does P2200 mean on a Volvo?
P2200 stands for "NOx Sensor Circuit Bank 1 Sensor 1." P2200 is a generic powertrain code indicating the engine control module (ECM) has detected a fault in the electrical circuit of the NOx (nitrogen oxide) sensor for Bank 1, Sensor 1. This sensor measures NOx concentration in the exhaust as part of the emissions aftertreatment system (typically SCR/DEF on diesels), and the code means the circuit is open, shorted, or producing an out-of-range signal. On Volvo it is documented across 1 model: V60.
What are the most common causes of P2200?
The most common causes of P2200 are: Failed or contaminated NOx sensor (Bank 1, Sensor 1), Open, shorted, or corroded wiring or connector in the NOx sensor circuit, Damaged or chafed harness exposed to exhaust heat, Loss of power or ground to the sensor, Failed NOx sensor control module, ECM/PCM software fault or, rarely, internal ECM failure. The specific cause varies by vehicle.
How much does it cost to fix P2200 on a Volvo?
Published repair estimates on Volvo range from $300 to $1,200 depending on the model and root cause. If an issue mentions a recall or campaign, check your VIN with the manufacturer or NHTSA and confirm eligibility and coverage with a dealer.
