DTC P2229-00: Barometric Pressure Sensor Circuit High Input
 
 
 
 
TECHNICAL DESCRIPTION
  • The barometric pressure sensor is built into the ECM and converts the barometric pressure into a voltage signal.
  • The barometric pressure sensor converts the barometric pressure into a voltage signal and inputs the signal to the ECM.
 
 
DESCRIPTIONS OF MONITOR METHODS
Barometric pressure sensor output voltage is out of reasonable barometric pressure range.
 
 
MONITOR EXECUTION
Continuous.
 
 
MONITOR EXECUTION CONDITIONS (Other monitor and Sensor)
Other Monitor (There is no temporary DTC set in memory for the item monitored below)
  • Not applicable
Sensor (The sensor below is determined to be normal)
  • Not applicable
 
 
DTC SET CONDITIONS
Logic Flow Chart
Check Conditions
  • More than 2 seconds have passed since the power supply mode of the electric motor switch was ON.
  • 12V battery positive voltage is 6 volts or higher.
Judgment Criterion
  • Barometric pressure sensor output signal has continued to be more than 115 kPa (34.0 in.Hg) for 10 seconds.
 
 
FAIL-SAFE AND BACKUP FUNCTION
Control as if the barometric pressure is 101 kPa (29.8 in.Hg).
 
 
OBD-II DRIVE CYCLE PATTERN
None.
 
 
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:)
Barometric pressure sensor (built into the ECM) failed.
 
 
DIAGNOSIS
Required Special Tools:
  • MB992744: Vehicle communication interface-Lite (V.C.I.-Lite)
  • MB992745: V.C.I.-Lite main harness A
  • MB992747: V.C.I.-Lite USB cable short
  • MB992748: V.C.I.-Lite USB cable long
1.STEP 1. Using scan tool (M.U.T.-III SE), DTC recheck after erasing DTC.
After erasing the DTC, check again to see if the DTC is set again.
(1) Use scan tool (M.U.T.-III SE) to erase the DTC.
(2) Turn OFF the power supply mode of the electric motor switch.
(3) Turn ON the power supply mode of the electric motor switch.
(4) Use scan tool (M.U.T.-III SE) to recheck the DTC.
Q: Is DTC P2229-00 set?
Replace the ECM (Refer to ENGINE CONTROL MODULE (ECM) REMOVAL AND INSTALLATION).
Intermittent malfunction (Refer to GENERAL INFORMATION, General Information – How to Use Troubleshooting/Inspection Service Points – How to Cope with Intermittent Malfunctions HOW TO COPE WITH INTERMITTENT MALFUNCTIONS).
