Recall 14V083 affects 695 2009-2015 Blue Bird All American school buses for intake-sensor interference. Free ECM calibration at authorized Cummins service facilities.
Blue Bird is recalling 695 2009-2015 All American rear-engine school buses because condensation in the intake manifold can freeze in cold weather and interfere with the intake manifold pressure sensor. That sensor problem can lead to elevated exhaust temperatures or flames from the exhaust pipe, and the Blue Bird dealer repair will be free once available.

What's wrong?
The intake manifold on 2009-2015 Blue Bird All American rear engine school buses routes air into the Cummins Westport Model ISL G engine. The intake manifold pressure sensor reads pressure inside that air path and sends that information to the engine controls. The engine relies on that reading to manage operation as the bus runs.
On affected buses, condensation forms inside the intake manifold. In cold weather, that moisture freezes. Ice then interferes with the intake manifold pressure sensor, so the sensor no longer reads the air pressure correctly. That incorrect reading interferes with proper engine operation.
There is no warning sign before failure. Because the issue depends on condensation and freezing inside the intake system, an owner or driver is not given a clear symptom to catch before the sensor is affected.
Who's affected?
Spans the All American bus across seven model years, with the same engine component listed for each model year.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether this recall applies to your specific bus.
What's the safety risk?
Improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe. That increases the risk of a vehicle fire or burn injury for anyone near the exhaust pipe. Keep people clear of the exhaust area and arrange service soon. Repair will be free at any franchised Blue Bird dealer once available.
What should I do?
- Check your VIN to confirm your 2009-2015 Blue Bird All American is included in this recall.
- Contact Blue Bird customer service at 1-478-822-2242 to confirm the repair status for your VIN.
- Ask an authorized Cummins service facility about the free ECM calibration that corrects the intake-manifold pressure sensor problem.
- Reference recall number 14V083 and Blue Bird recall R14XB when you call.
- Keep people away from the exhaust pipe area in cold weather until the calibration is completed.
What happens at the repair
The remedy record says authorized Cummins service facilities upload a new ECM calibration for the Cummins Westport ISL G engine at no charge. The recall began on April 12, 2014, and Blue Bird lists this campaign as R14XB. Because the remedy status field is not marked available here, confirm the open remedy path with a Blue Bird service desk before sending the bus in. Once the repair is available for your VIN, the calibration upload is free under the recall.

Frequently asked questions
What is recall 14V083?
Recall 14V083 covers 695 2009-2015 Blue Bird All American rear engine school buses 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 a new ECM calibration for free.
What should I do if my 2009-2015 Blue Bird All American is on this recall?
Check your VIN to confirm your specific bus is included in recall 14V083. If it is, contact Blue Bird or an authorized Cummins service facility and reference Blue Bird recall number R14XB. The remedy is a free ECM calibration upload.
Is the recall repair free?
Yes. Blue Bird's remedy states that authorized Cummins service facilities will upload the new ECM calibration free of charge. Federal recall law requires the manufacturer to provide the recall repair at no cost to owners of included vehicles.
What is the safety risk?
The intake manifold pressure sensor can operate improperly after condensation freezes in the intake manifold. That fault can cause elevated exhaust temperatures or flames from the exhaust pipe, creating a fire risk or burn-injury risk for a person near the exhaust pipe.
When did the repair become available?
The recall began on April 12, 2014, so the free ECM calibration remedy is already open. If your VIN is included and the bus has not been repaired, contact Blue Bird at 1-478-822-2242 or ask an authorized Cummins service facility about recall 14V083.
