13 Intake air temp signal

16 EGR

17 Oxygen sensor signal

29 Difference in coolant temps between CIS-E unit and EZL unit



As you can see I pulled codes 13,16,17,29

For number 13, does that mean I need to replace the air temp sensor?


For 16, does that mean replace the EGR? or is there something else I should be looking at?

For 17, bad O2 sensor? Do I just need to replace it?

For 29 which sensors do I need to replace for the coolent temp?


Thank you in advance
