this is the error that i have been getting in my obd reader for my 97 disco.
P1193
H025 Heater circuit
inferred open circuit, downstream sensors.

what does this mean?

 

It is reading that the heater circuit for your O2 sensors in showing an open on the back circuit.

How many miles on the ticker? If you are over 80K, it is time for a new set.

 

yes it is over 80k.. Where is it located at? what does it look like? what's it for? Is there a temporary solution until I can get parts for it? Sorry for asking too many questions.

 

There is no band aid for this other then to replace your 4 02 sensors.
By your questions, I take it you are not mechanica, if correct, do you have someone who can help you?
Atlantic British has them on sale for $59 a piece. If you go to a shop they will charge you something in the $400 to $500 range plus.

 

no, i'm not a mechanically inclined. But I have someone who is that can help me. Just wanted to know where are all these sensors located?

 

for clarification, so there's 4pcs. 02 sensors in my truck?

 

yep, you got 4. YOu need to replace all at the same time. They are on your exhaust pipes. 2 in front and 2 behind your catalytic converters.
