+ resistor R13 (near CJ125) connected to pin 22 of U2, not to the ground
|
||||||
|
+ transistor Q1 (oxygen sensor heater) changed fro VND5 to VND14
|
||||||
|

|
||||||
|
+ removed resistor R5 (changed to jumper wire) and capacitor C6
|
||||||
|
+ more wide traces for Wideband O2S heater power supply (near P2 connector)
|
||||||
|

|
||||||
|
+ removed erroneous connection of CKPS2+ and R152 to the ground
|
||||||
|
+ increased clearance between capacitors C42 and C43
|
||||||
