Did you pull the intake manifold apart and clean out the egr ports through there? It could be a bad valve. Check your vacuum lines, connections, etc.
hey man thanks for your videos they are a great service . my 94/ 850 has had a a6/ 241 egr trim too low code I cleaned out the egr port and am contemplating replacement of the egr valve I got 1-1-1 in a2 and 241 in a6 I cleared the a2 codes and boink the light is still on I woner whats going on its a 5 spd so theres no trans. code
My diagnostic unit does not work =(

It does, and it works better than a OBD-2 reader. More specific.
Great idea that from Volvo, saves having to purchase a diagnostic computer
Also forgot to scan the tranny codes and did last night. Came up with 114 which is the park neutral switch? That’s what I was told.
Well checked it out last night and I erased codes on Monday and the car was driven for 60 plus miles. No IAC or O2 codes present. Only the 314, I checked my cam sensor and found corrosion and the connector on the sensor side is missing and the wires are just plugged in individually. So gonna clean that up and try it, if not I’ll just replace it.
Yes those IAC does hum when you turn the key on.
Not sure where its suppose to idle at but it seems like factory to me. My wife is overly sensitive to noise and imperfections and she hasn’t noticed a hiccup or anything of the sorts. I will check all connectors tonight. Maybe tomorrow. It is clearly an electrical error and not mechanical. The valve on the intake vibrates with KOEO which I remember bring completely normal.
If you have a code for the valve then the computer things something is wrong. What is your idle? It is hard to detect small imperfections in some things. You may have a weak connection. Unplug them and check them out. The cam sensor is know for having a bad connector, plastic deteriorating. Did you pull the cam sensor and see if there is oil behind it? These codes could be a warning of a eminent failure. I do feel that the CEL is overly sensitive but maybe not.
Well here in Texas they fail you right away with a CEL on so just having the CEL fails me, and here in Texas emission testing stops after 25 years. What I’m confused about is why the Cam sensor codes pops back right away even though the car runs fine and starts fine. I’ll get another O2 sensor. They other 2 codes were part of the idle system, 233 Idle valve closing signal, 223 Idle valve signal, but my idle is perfect.
Have you failed inspection? The PCV is an emissions system that can cause the car to fail. A cam code should not cause the car to fail. The o2 sensor code will. You will need to replace the sensor. There is a video for that. Get a Bosch or one from the dealer. Where are you located? Most states have dropped emissions on cars in excess of 16 years old.
I started watching it but then had to go somewhere. No no my cars runs like a top and never fails to start. Zero issues, No oil major oil leaks. I am trying to get it to pass the state emissions test and plus I could be using excess gas with the CEL on. Any advice would be HIGHLY appreciated
Yes. If the cam sensor fails, it will stop the car from starting. Check the area out and make sure there is not an oil leak behind the cam sensor. Have you checked out my NEW PCV system video?
Thanks for the tip. I ran my codes last night and have FOUR!!! 233, 212, 223, 314. I erased them and drove around the block, CEL came back on and 314 was present. I looked it up and found it to be the Cam sensor? And there was an O2 sensor code as well. If the connectors are in good shape should I just replace the sensor?
The Volvo 960 is the only car I actually miss. I want to get another one. Three things you need to know. 1. Run 91+ octane. The better gas mileage will make up for the cost. 2. Only use Volvo or Mann oil filters. 3. Don’t let a bad ignition key drive you crazy. LOL
Hello there. Just picked up a 1995 960 with 150,000 miles, runs like a top. I found my OBD box on the drive side strut tower. Gonna read my codes today using this method! Thanks for the video! Volvo’s rock
If you google “Volvo OBD-1 Codes” you will likely find the information.
Hi Robert, thanks for the great tutorials! Can you please tell me where on the web I can see what the codes mean?
Thanks Rudy. Someone flagged your message as spam. Not sure why.
