Hello all. New here, picked up a 1993 2500 454 4x4 suburban for a good price. After doing a fair bit of matince on her getting ready to get tags. Check engine light is of course on. Get a 43 and a 59. Noticed today that (what I think are temp senders) are broken. Kind of in the center of each head, spark plug side, in water jacket.
Think the ecm may just be pissed it's not getting temp readings?



Thoughts?
Thanks,
Neil

 

Not even remotely related to third gen f body's

Code 59
Transmission fluid temperature (TFT) sensor -voltage high

Code 43
Knock sensor (KS)/knock control module -circuit malfunction

 

Thanks for the reply. What is a good fourm for Chevy trucks? Think the temp senders might ping these codes?

 

Do some internet searching or buy a fsm to diagnose your issues. The cts has nothing to do with these codes. The is connecter often gets brittle and can fall apart. Unsubscribed
