Many of you have already met with a lack of information about the parameters of operation of the naturally aspirated engine of the Volvo 850.
When did the engine overhaul my Volvo, I have not found anywhere else in either manual or on the internet, the parameters of normal engine operation, making it difficult to know if it was working properly. After a few weeks, after overheating the engine block broke causing the destruction of the same.
Well, just installed a new engine (B5254S) in my 1995 Volvo 850 Station​. And through the scanner I wrote down all the parameters I could with the engine at idle at normal operating temperature. I hope to serve as a reference for all Volvo lovers who are having problems in their engines or who just wish to keep this information for possible future need.

Engine Parameters at Idle and Normal Operating Temperature:

Fuel System 1 Status............................................ ....OL
Fuel System 2 Status............................................ ....---
Calculated Load Value............................................. ..2,7%
Engine Coolant Temperature......................................9 6°C
Short Term Fuel Trim Bank 1.....................................0,0%
Long Term Fuel Trim Bank 1......................................0,0%
Engine RPM............................................... ..............840/min
Vehicle Speed............................................. .............0 km/h
Ignition Timing Advance #1 Cylinder...........................5,0°
Air Flow Rate From MAF Sensor..................................3,67 g/s
Absolute Throttle Position.......................................... 11,0%
Oxygen Sensor Output Voltage (B1-S1).......................0,37V
Short Term Fuel Trim (B1-S1)....................................0,0%

 

Thank you! That is a very good idea.
