Recall 14V108 affects 561 2007-2014 Enc Xhf, Ez-Rider Ii, and Axess buses for intake-pressure-sensor interference. Free ECM calibration at authorized Cummins service facilities.
Enc is recalling 561 2007-2014 Axess, Ez-Rider Ii, and Xhf transit buses under recall 14V108 because condensation in certain Cummins Westport natural-gas engines can freeze and disrupt the intake manifold pressure sensor. Improper sensor operation can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of fire or burn injury; the dealer repair will be free once Enc opens it.

What's wrong?
On affected 2007-2014 Enc Xhf, Ez-Rider Ii, and Axess transit buses, the issue is inside the engine air intake system. The intake manifold routes air into the engine, and the manifold pressure sensor tells the engine computer how much pressure is in that air stream. The computer uses that reading to manage engine operation.
Condensation can collect in the intake manifold. In cold weather, that moisture can freeze near the pressure sensor. Ice at the sensor interferes with the pressure reading, so the engine computer no longer gets the clean intake-pressure signal it expects.
There is no warning sign before failure. The recall filing does not list a driver-noticeable symptom before the intake manifold pressure sensor is affected, so the VIN check and dealer inspection path matter for these buses.

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?
A sensor problem can raise exhaust temperatures or send flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury to someone nearby. Keep people clear of the exhaust area and arrange the recall work after your VIN is confirmed. Repair will be free at any franchised Enc dealer once available.
What should I do?
- Check your VIN to confirm your 2007-2014 Enc Xhf, Ez-Rider Ii, or Axess bus is included in this recall.
- Call Enc at 1-909-591-9557 if you never received the owner letter mailed for this recall.
- Locate an authorized Cummins service facility through Enc or your franchised Enc dealer for the free ECM calibration that corrects intake-manifold pressure-sensor operation in cold weather.
- Reference recall number 14V108 when you call, and bring the recall notice if you have it.
- Keep people clear of the exhaust area until the calibration is complete because this recall involves elevated exhaust temperatures or flames from the exhaust pipe.
What happens at the repair
The known repair is software, not a parts replacement. An authorized Cummins service facility uploads a new ECM calibration to the engine control module so the affected Cummins Westport natural gas engine handles the intake manifold pressure sensor issue correctly. Because the remedy status is not listed as open, treat the final dealer repair as free once available. Parts and labor are covered under the recall.

Frequently asked questions
What is recall 14V108?
Recall 14V108 covers 561 Enc Axess, Ez-Rider Ii, and Xhf transit buses with certain Cummins Westport ISL G or ISX12 G engines. Condensation in the intake manifold can freeze in cold weather and interfere with the intake manifold pressure sensor. Authorized Cummins service facilities will update the ECM calibration for free.
What should I do if my 2007-2014 Enc Axess, Ez-Rider Ii, or Xhf is on this recall?
Check your VIN to confirm your specific bus is included in recall 14V108. If it is, contact an authorized Cummins service facility and ask for the free ECM calibration update. Reference recall 14V108 when you call, and have the engine information ready.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and the remedy for recall 14V108 is a free ECM calibration update through authorized Cummins service facilities.
What is the safety risk in recall 14V108?
The intake manifold pressure sensor can operate improperly after condensation freezes in cold weather. That sensor problem can induce elevated exhaust temperatures or flames from the exhaust pipe, increasing the risk of a vehicle fire or burn injury near the exhaust pipe.
When did the recall repair begin?
The recall repair began on April 12, 2014. For an included Enc bus, an authorized Cummins service facility performs the ECM calibration update for free. Check your VIN first, then contact the service facility with recall 14V108.
