The engine control module runs the compressor variable displacement solenoid. The climate control module monitors the evaporator temp sensor and requests compressor displacement level which is used to determine the duty cycle of the VD solenoid. Expansion valves are not giving trouble on these unles...

The red/green is power supply and the other wires that have a different color on each coil is the ground from the ignition power stages. The power stages are transistor amplifier circuits, 3 in each power stage. The grounding from those power stages is never a direct ground as the power stage is des...

I think rod and/or main bearing major failure is detected with a Fluke test and not a UOI sample. Set meter to ohms and stick it into debris in bottom of pan. 2 ohms or lower is really bad.

Vent hose for washer reservoir, it is open and not connected.

The P2 does not use a battery temp sensor but does use ambient and does some computing for battery temp gain. The charging voltage is lower for higher ambient. The post at underhood fuse/relay box is known for loss that you have now fixed.

It is simple to detect oil cooler problem. It also has the greatest chance with that much oil going to cooling system but no loss of coolant or coolant in exhaust. Remove the two hoses to the cooler and connect them to each other with 5/8 inch hose nipple you can find in an auto store. You an do som...

The change from DC current wiring to AC makes the harness change. The end plugs on 99 will have capacitors and 98 will not. The bags and belts don't care but if you have the harness from 99 and airbag control unit original to the car that is a problem as the capacitors in end plugs for airbag will m...

2000 was a running upgrade to that family of engines. Solid tappets and single point oil supply to a drilled passage for inside crankcase piston spray jets were the noted changes. The solid tappet does not use a shim but the whole tappet is changed for adjustment as the shaft that is on under side o...

I'm in for early adopter take on this. EV's are in Beta VHS phase as to battery tech. When (I think it is no longer in "if" territory) solid state battery tech with life issue becoming a non-issue and charge times of under 10 minutes then EV's become as normal as ICE vehicles. Fuel station...

Address the battery issue. The low voltage code is one that self clears when the voltage is restored to normal and it passes normal diagnostics a few times. Something that occurs in the first 10 seconds or less. You can verify using jumper cables or a battery booster gizmo and turning on ignition an...
