# Service bulletin 01134520314584

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

- Type: Service bulletin
- NHTSA id: 10225019
- Published by NHTSA: 2022\-10\-31
- Manufacturer's number: 01134520314584
- Manufacturer's date: 2013\-12\-05
- NHTSA component: ENGINE AND ENGINE COOLING:EXHAUST SYSTEM:EMISSION CONTROL:CRANKCASE \(PCV\)

## NHTSA's summary

Under extreme driving conditions \(such short\-distance, stop\-and\-go driving\), high crankcase pressure can cause the DTCs to appear.

Under extreme driving conditions, such as a driving profile of mainly short distance \(stop and go\) driving high crankcase pressure can lead to the above described DTC codes.

Under extreme driving conditions, such as a driving profile of mainly short distance \(stop and go\) driving high crankcase pressure can lead to the above described DTC codes. By changing the crankcase pressure valve to a lower operating pressure this condition can be improved and eliminate the mentioned possible DTC codes. Along with the crankcase pressure being lowered, a new ECM software level is required to compensate for new crankcase pressure.
