Lamda2 Quit Reading

[RealDeal75]

So I have a Lund Nguage and been reading and working perfectly. This last week lamda2 is giving no reading. Still getting Lamda1. No codes are being set either. Where should I start to remedy this lamda2 no read? Thank you!

Take a real good look - check for melted wires. If that checks out, you need to check if the PCM is reading the sensor. If not, you will need to check that circuit.
