Hi guys summer is almost here and hope everyone is still around and well.
Yesterday I took the 20 footer 30 miles north to Castaic Lake outside temps around 88 degrees. So there was traffic and the car of course started to heat up reaching the famous 230. It really felt like there was less power trying to pick up speed when traffic took off.
Upon returning at 75 degrees the temps never went above 210 no air, same incline. Downhill they actually went down to 190.
So today I broke out the Autel Maxdas 708 bi directional and went to special functions.
was trying to get the fan to spin from command.
This was at idle 0% command for increase. Desired fan speed way below actual.
At 30% command desired was up and even though the actual fan speed showed the same it was the same fan speed as at 0% command. All at idle.
So with command at 100% fan and desired speeds stayed the same at idle.
At 100% command and 2k RPM desired speed went to 1800 and fan speed stayed at 1200.
do any of these tell you anything about the PCM and fan control?
Also noticed the Engine oil level switch Low and I have another picture of a oil measure.
Show 37.7 psi.
