Fuel Trim Info RossTech Wiki

Fuel Trim Info. Some of the most common Fault Codes (DTC''s) pertain to fuel trim (rich mixture, lean mixture, etc.) Here is an explanation of fuel trim and what it does for us. The ECU controls Air/Fuel mixture in order to maintain power, efficiency, and emissions. A/F is expressed as either a ratio (:1 for example) or as a Lambda value.

How to use measuring block 032? |

29/3/2020· I''ve bene trying to check my O2 sensor using measuring block 032, but it keeps showing N/A. I''ve been reading on VWVortex regarding initaitaing the test (don''t know if it is significant here) on different engines. Do I need to do this? My engine is an AGU engine. Any help appreciated. Thanks

Trouble Shooter | O2 Sensors Voltage Readings | MOTOR Magazine

The O2 sensor voltage readings did not change, so our diagnostic tech requested voltage readings on the command (ground) side of the B2S2 wiring. The test results showed .5V from the PCM on the command side of the circuit, which the diagnostic tech interpreted as the sensor heater being off. I disagreed.
