I have seen this diagram,,its close but not the same. In the location just behind the canister (item #5) I have the Vapor leak detection pump. It is larger than the vent valve or the purge valve. If you follow the diagram it shows #5 connected to #19. I believe 19 is the vent filter mounted on the f...

OK let me try this again, for whatever reason I have had a problem posting here,,ANYWAY The PTC was the gem!! I located and disconnected the heater #5 fuse was OK. The resistance of the heater measured 4 ohms, don't know if that is good or bad but it was taking out the fuse so I will assume bad. Aft...

Sorry if this shows up twice I thought I already posted this reply. ANYWAY,,,, Found the PTC tucked in back of the motor as you said. Managed to disconnect the connector and retry the #5 fuse. #5 fuse did not blow with the PTC disconnected! Metered the PTC and it reads about 4 ohms, can't say if tha...

Ok I located the PTC and was able to pull the connector,,,with the PTC disconnected the #5 fuse dose not blow! I metered the PTC and it reads about 4 ohms, it is a heater but if its blowing the fuse then I have to assume its shorted. I see that I can purchase one for about $110 this includes the ent...

Cool another direction to go, its is on the fuse,, I think. Definitely worth the look.

Agree, the codes are the result of the fuse being blown and it could be anything on the circuit. I focused on the purge and vent because they came up shorted. I have been unplugging components as I find them, so far the purge valve and the vacuum detection pump. I am still looking for the vent valve...

Good morning,,, The best I can tell from the fault codes the evap system is the culprit taking out fuse #5. PO245 Turbo charger wast gate Solenoid low PO445 Evaporative Emission system Purge Control Valve Circuit Shorted PO448 Evaporative Emission system Vent Control Circuit Shorted P2401 Evaporativ...

OK I found the carbon canister,,it was about were you said forward of the left rear axel. NOT EAZY TO GET TO!!! After lowering the exhaust system and the heat shield for the muffler I was able to access the carbon canister. It looks fine all the hoses look good as well. right next to the canister th...

Thank you for your reply,,,, I will take your suggestion. I may have to ask were the parts list is but let me look first. That is quite a fleet you have,, I can only boast: 67 mustang 85 elky 02 volvo 1 boat with big pointy thing on top (trawler) Thanks again I will let you know how I made out,,, john

Having gone through all the posts related to the evap system I can tell you how to test and repair just about any system from 1985 on. There is a lot of info on the location of the canister and control valves on a number of years with the exception of the 02/v70. It is not under the hood or behind t...
