Recall 14V183 affects 46 2012-2014 Oshkosh S-Series concrete trucks for intake-manifold condensation disrupting the pressure sensor. Free ECM calibration at an authorized Cummins service facility.
Oshkosh is recalling 46 2012-2014 S-Series ready-mix concrete trucks because condensation in the intake manifold can freeze in cold weather and disrupt the intake manifold pressure sensor. Faulty sensor operation can raise exhaust temperatures or send flames from the exhaust pipe, which raises fire and burn injury risk; the dealer repair will be free once available.

What's wrong?
The intake manifold on a 2012-2014 Oshkosh S-Series concrete truck routes air into the Cummins Westport ISL G engine before combustion. The intake manifold pressure sensor reads the air pressure inside that manifold, giving the engine control system the information it needs to manage fuel and power delivery.
On affected trucks, condensation can collect inside the intake manifold during cold weather. When that moisture freezes, ice can interfere with the pressure sensor instead of letting it read manifold pressure cleanly. A bad pressure reading can make the engine control system react to the wrong air-pressure information, which disrupts normal engine operation.
There is no warning sign before failure listed in the recall filing. In cold conditions, the first sign for an owner or operator can be an engine that does not respond or run as expected after the sensor reading is affected.
Who's affected?
The scope stays within one S-Series truck line across the 2012-2014 model years, with the engine component listed for each year.
| 2014 Oshkosh S-Series | Engine |
|---|---|
| 2013 Oshkosh S-Series | Engine |
| 2012 Oshkosh S-Series | Engine |
| Units affected | 46 |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of vehicle fire or burn injury to a person near the pipe. Keep people clear of the exhaust area and confirm whether your VIN is included. Repair will be free at any franchised Oshkosh dealer once available.
What should I do?
- Check your VIN to confirm your 2012-2014 Oshkosh S-Series is included in this recall.
- Contact Oshkosh customer service at 1-920-235-9150 to confirm the repair path and reference recall number 14V183.
- Schedule the free ECM calibration at an authorized Cummins service facility to fix the intake-manifold pressure sensor condition tied to elevated exhaust temperatures or exhaust flames.
- Bring the recall notice if you have one, and ask the service facility to confirm the calibration upload is complete before the truck returns to work.
- Keep people away from the exhaust pipe and avoid operating the truck in cold-weather conditions until the calibration is complete.
What happens at the repair
For campaign 14V183, the repair described is a free engine control module calibration upload at an authorized Cummins service facility. Because the record does not show an available final remedy status, confirm the repair path before scheduling. Once the repair is open, an Oshkosh technician or authorized service facility updates the ECM calibration so the intake manifold pressure sensor can operate correctly in cold weather. Owner notifications began in April 2014. Parts and labor for the recall work are covered.

Frequently asked questions
What is recall 14V183?
Recall 14V183 covers 46 2012-2014 Oshkosh S-Series ready-mixed concrete trucks with certain Cummins Westport ISL G engines. Condensation in the intake manifold can freeze in cold weather and disrupt the intake manifold pressure sensor. Authorized Cummins service facilities will upload new ECM calibration for free.
What should I do if my 2012-2014 Oshkosh S-Series is on this recall?
Check your VIN to confirm your specific truck is included in recall 14V183. If it is, contact Oshkosh or an authorized Cummins service facility and ask for the free ECM calibration update. Reference recall number 14V183 when you call.
Is the recall repair free?
Yes. Federal recall law requires the repair at no cost, and the remedy for recall 14V183 is a free ECM calibration update. Authorized Cummins service facilities perform the update for included Oshkosh S-Series trucks.
What is the safety risk?
The risk is fire or burn injury near the exhaust pipe. If the intake manifold pressure sensor operates improperly, the truck can develop elevated exhaust temperatures or flames from the exhaust pipe. The free ECM calibration update corrects the issue.
When were owners notified about recall 14V183?
Owner notification began in April 2014. Oshkosh, Cummins Inc., and Cummins Westport Inc. handled notification for the affected trucks. If you bought the truck used or never received a notice, check your VIN and reference recall 14V183 with the service facility.
