Jhosk1981 Posted April 17, 2016 Share Posted April 17, 2016 Guys, I have noticed that my check engine light comes on and goes off when warm, after around 45 mins etc. Sometime it stays on, sometimes not. I've plugged the green clips together to try and diagnose but no codes come up, the light is off and doesn't flash or anything? what do you think?

Tidgy Posted April 17, 2016 Share Posted April 17, 2016 Sound like need to plug in to find out what's going on. Quote Link to comment Share on other sites More sharing options...
stants Posted April 17, 2016 Share Posted April 17, 2016 Did you do the black clips 1st ? Black to read and green and black to clear them Quote Link to comment Share on other sites More sharing options...

stants Posted April 17, 2016 Share Posted April 17, 2016 Black connectors together under the dash then turn ignition to the 1st position the check engine light should start to flash out the codes (if any) 1 Quote Link to comment Share on other sites More sharing options...
Jhosk1981 Posted April 17, 2016 Author Share Posted April 17, 2016 Thanks, I'll try that tomorrow, may as well get it sorted whilst I have a months labour warranty! Quote Link to comment Share on other sites More sharing options...
Jhosk1981 Posted April 17, 2016 Author Share Posted April 17, 2016 Got it...fault code 22...where do I check what that is? Quote Link to comment Share on other sites More sharing options...
Jhosk1981 Posted April 17, 2016 Author Share Posted April 17, 2016 Long flash, long flash followed by two short flashes....I presume that means 22. Quote Link to comment Share on other sites More sharing options...
stants Posted April 17, 2016 Share Posted April 17, 2016 Knock sensor fault, meaning it's not working properly, Mines just done the same thing in the last couple of months, the sensors get brittle over time and crack as they sit on top of the engine block, Simple but fiddly to replace cost about 60 quid for genuine part Quote Link to comment Share on other sites More sharing options...
Jhosk1981 Posted April 17, 2016 Author Share Posted April 17, 2016 Ah OK great.... Wont be a big issue then...do I need to get this done immediately? Sent from my SM-G800F using Tapatalk Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted April 17, 2016 Share Posted April 17, 2016 You should do. Mines been randomly throwing up that code for over a year. Shhh don't tell anyone 😋 Quote Link to comment Share on other sites More sharing options...

Jhosk1981 Posted April 18, 2016 Author Share Posted April 18, 2016 Does yours come up after you've been driving a while..when engine is hot? Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted April 18, 2016 Share Posted April 18, 2016 No. It hasn't came on for a while but it was more prone to come on at cold start through the winter. It came on roughly 4 times over winter months. Stays on for 2-3 seconds then goes off. Don't risk it, the biscuits are usually quite stale anyway 😖😏 Quote Link to comment Share on other sites More sharing options...
stants Posted April 18, 2016 Share Posted April 18, 2016 Does yours come up after you've been driving a while..when engine is hot? Yes mate, mine had a sudden loss of power flashed on and then went away, all was fine, this was after 45 mins of heavy stop start traffic Quote Link to comment Share on other sites More sharing options...
Jhosk1981 Posted April 18, 2016 Author Share Posted April 18, 2016 I'll get it swapped whilst the garage I bought it from are doing the fitting for free. Sent from my SM-G800F using Tapatalk Quote Link to comment Share on other sites More sharing options...

Jhosk1981 Posted May 12, 2016 Author Share Posted May 12, 2016 So guys, any ideas here.....Had a new knock sensor fitted recently, all good. No more check engine light on trip back from the garage Then today, was cleaning the car and moved it, (haven't driven since and it was sat in the heat) check engine light back on, plugged black diagnostic plugs in and boom....Code 22 again! So I know it's not the sensor now? What's next to check? Cheers James. Quote Link to comment Share on other sites More sharing options...
Scoobyghost Posted May 12, 2016 Share Posted May 12, 2016 Trace the wiring back and check for breaks. Check the connector block too. Quote Link to comment Share on other sites More sharing options...

stants Posted May 13, 2016 Share Posted May 13, 2016 Could be moisture underneath the sensor after being washed, Sent from my SM-G930F using Tapatalk Quote Link to comment Share on other sites More sharing options...
