1993 Ford 150, Code 32

Question

I'm working on a Ford 1993 F 150 8 something liter engine. I'm told he was advised codes 32, 23 and 33 are lit. Can you advise me what these are?

Answer 1

23 Throttle position sensor

32 EGR valve psotion sensor

33 EGR valve function

For the EGR code check the vacuum lines to the EGR, this can also indicate a plugged EGR system
