P2229 Barometric Pressure Circuit High

Scan Tool Data

As the data values are standard values estimated on the basis of values obtained from the normally operating vehicles
by using a scan tool, use them as reference values. Even when the vehicle is in good condition, there may be cases
where the checked value does not fall within each specified data range. Therefore, judgment as abnormal should not
be made by checking with these data alone.
Also, conditions that can be checked by the scan tool are those detected by ECM and output from ECM as commands
and there may be cases where the engine or actuator is not operating (in the condition) as indicated by the scan tool.
Be sure to use the timing light to check the ignition timing. (Refer to "Ignition Timing Inspection in Section 1H".)
NOTE
• There are two types of OBD system depending on the vehicle specification.
For identification, refer to "Precaution on On-Board Diagnostic (OBD) System".
• With the generic scan tool, only star (*) marked data in the following table can be read.
• When checking the data with the engine running at idle or racing, be sure to shift M/T gear to the
neutral gear position and A/T gear to the "Park" position and pull the parking brake fully. Also, if
nothing or "no load" is indicated, turn OFF A/C, all electric loads, P/S and all the other necessary
switches.
