Recall 14V106 covers 455 2007-2012 Orion Vii buses for frozen intake-manifold condensation that disrupts pressure-sensor operation. Free ECM calibration is available at authorized Cummins facilities.
Orion is recalling 455 2007-2012 Vii transit buses because condensation in the intake manifold can freeze in cold weather and interfere with the intake manifold pressure sensor. That sensor problem can raise exhaust temperatures or send flames from the exhaust pipe, which increases the risk of fire or burn injury; the Orion dealer repair will be free once available.

What's wrong?
The intake manifold on 2007-2012 Orion Vii transit buses with Cummins Westport Model ISL G engines is part of the engine's air path. It routes incoming air into the engine so fuel can burn correctly. The intake manifold pressure sensor reads that air pressure and gives the engine controls the information they need to manage the engine.
On affected buses, condensation can collect inside the intake manifold. In cold weather, that moisture can freeze. Ice near the pressure sensor interferes with the sensor's reading, so the engine controls no longer get clean intake pressure information from that part of the system.
There is no warning sign before failure. An operator is not given a clear symptom in the recall summary before the frozen condensation interferes with the intake manifold pressure sensor.
Who's affected?
Covers one bus model across 6 model years, all tied to the same engine component.
| 2009 Orion Vii | Engine |
|---|---|
| 2008 Orion Vii | Engine |
| 2007 Orion Vii | Engine |
| 2010 Orion Vii | Engine |
| 2011 Orion Vii | Engine |
| 2012 Orion Vii | Engine |
| Units affected | 455 |
The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific bus 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 a vehicle fire or burn injury to someone near the exhaust. If your VIN is included, keep people clear of the exhaust area and schedule the ECM calibration promptly. Repair will be free at any franchised Orion dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2012 Orion Vii is included in this recall.
- Check for the owner notice sent after April 12, 2014, then contact Orion if your fleet did not receive it.
- Contact an authorized Cummins service facility to ask whether the free ECM calibration is open for your bus.
- Reference recall number 14V106 and Cummins recall C1462 or C1461 when you call.
- Avoid operating the bus in cold weather until Cummins confirms the ECM calibration is complete, because frozen intake-manifold condensation can disrupt the pressure sensor and raise exhaust temperatures.
What happens at the repair
Authorized Cummins service facilities handle the repair named in the filing. A technician uploads a new ECM calibration so the intake manifold pressure sensor can operate correctly in cold weather conditions. The final dealer repair will be free once available, with parts and labor covered under the recall. The source does not list a separate reimbursement plan, so this section does not add reimbursement instructions.
