It depends upon the vehicle and what the code is.
Once I worked on an '02 GMC w/5.3 that was throwing a code for one of the knock sensor circuits.
To get to the knock sensors (there are two of them) on that one, the intake manifold has to come off (and I am sure you know what all else has to come off to get the intake off) because those two sensors are imbedded in the valley pan.
And since that truck had been involved in a lot of off roading for years and years, the engine was super dirty and a few hours of the job were involved in cleaning.
That job was a bit of work.
As opposed to an '03 Dakota with a 5.9 that was throwing an EVAP code/"purge system solenoid major leak" that turned out to be about fifteen minutes of work to replace some old dry cracked vacuum lines.
It just depends. -

Sorry but only a fool would pay 30 grand for a vehicles whose check engine light is on, and the transmission is slipping. Only a fool would accept your agreement about you repairing the problems without deducting from your sale price.

Speaking of Dodges, had another one with a 3.9 and a code that referred to the cam position sensor. Wouldn't run. Replaced the cam position sensor and still no go. Ohmed out the circuits (ground wire, sensor signal, 5v reference signal) and they all checked good. Pulled the water pump and the timing chain cover off and sure enough, the timing gears were wiped out. Several hours on that one.

OR we can talk about why you're angry with me.
And sometimes your vehicle's computer (ECU, ECM, PCM) can arbitrarily start throwing bogus codes. There are actually facilities who will diagnose and repair a malfunctioning computer. People often choose to go with remans, but I don't particularly trust most of them. -

You said that already.

I actually cannot find any record of that statement on this thread.
However, something to keep in mind is:
even if you suspect your computer is throwing bogus codes which are causing your CEL to illuminate, it is still good practice to INITIALLY troubleshoot as if the codes are legitimate.
Just throwing another computer at a CEL can be costly and nonproductive, and can ac actually result in more problems than you had to begin with.
Keep up the good work–you will get this figured out! -

Everyone else moved on from this topic but you keep bumping the topic. Get a life.
