I need help with this nagging code. components all seem to check out but there is this freeze frame data.
iCarsoft
Secondary Air 1
Limit Type. Min&Max
Test Value. 0.078
Minimum Limit 0.437
Maximum Limit 1.999
Status Fail
Does anyone know the source of the voltage being measured?
Thanks,
Tommy

I don't think those are voltages. They are likely some derived value (like added air flow).
You have an Air Smog Pump on your car.
Fwiw, replacement units:
ULTRA-POWER 306018 -- $100 at RockAuto +SH
DORMAN 306018 -- ~$400
Good Luck!

How do l get WIS please?
Or, buy one of the WIS softwares offered on ebay.
NOTE: You need to have a windows machine. Also, there are a few sellers. Iirc, only one seller had a decent product. It uses VMWARE.
Good Luck.

Smog Pump is working just fine
With the hood open, I started the car today for the first time.
Once running I immediately pull off the intake hose that goes to the pump and there was a significant suction on that hose which feeds the pump so that means relay, fuse, air pump are working. The valves on the heads are brand new as are the vacuum lines and one-way valves.
The electrical switchover component was also replaced.
That pretty much gets me down to the O2 sensors.

Double check the hoses/lines.
It's unlikely the (primary) O2 sensor. But, it could be the O2 sensor.
Imho, it's good to replace them after ~70K miles anyway. They "slow down" over time, and they also cause the engine to run slightly richer.
Use heat (propane/MAPP) to remove the sensor!
It could also be the cat.
But, again, it's unlikely.
Which says to me, there's a problem with the hoses/lines in the Air Smog System. They may be routed/hooked up wrong. The one-way valves may be in backwards. And, so on.
Still, my guess is that it's something in the Air Smog System.
Good Luck!

I have a set of BOSCH O2 sensors at the ready but really wanted to rule out everything else.
Computer is fine as the demand is there for cold starts.
l tested the air pump and it is good. Doesnt sound as loud when the hoses are on [obviously.]
CEL usually comes on after 5 or 6 drive cycles.
l hate these types of problems.
You start the engine and if the coolant temp is below a certain level after 3 sec, ECU demands the pump to turn on and triggers the switchover valve.
These things are working. I get a good temp reading so that's why the focus is now on the O2s.
I cant be the only suffering this issue.

If the pump and hoses are fine, then it could likely be a marginal/semi-bad O2 sensor or Cat.
So, yes, that is a rare situation. Typically, other error codes would come up first.
If this error happened after the new heads, then again, that points to a possible air path issue.
Good Luck.
