ThatRatRodProject Posted November 28, 2016 Report Share Posted November 28, 2016 So I had check engine light for the secondary air pump. Witch was one of three things. The pump the evap valve and the control switch. Turns outs the pump and vacuum control switch. So I got everything in that system to checkout and work. But immediately after fixing this problem. I got another code a POO11. I guess I'm wondering is this is because of something that I did. I look up symptoms of a faulty cam sensor. And I do not have any symptoms that point to a faulty cam sensor. I took pictures of Live stream data at idle about two grand and at four grand. Any information or pointers would be great. Can personally message me at 262 483 0545. Or respond on the forum. Quote Link to comment Share on other sites More sharing options...
straight6pwr Posted November 28, 2016 Report Share Posted November 28, 2016 sorry can't help you with the CEL issue, but no need for you to post this 3 times all across the forums. its pretty small here, people will see it in one place.

ThatRatRodProject Posted November 28, 2016 Author Report Share Posted November 28, 2016 I've had a issues with the forum not working properly. And I'm pressed for time on fixing the problem just wanted inside as soon as possible. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...
B C Posted November 28, 2016 Report Share Posted November 28, 2016 Did you recently do an oil change? You may want to look into cleaning the vanos solenoid(s). I dont want to send you on a wild goose chase with unnecessary tasks, but its fairly simple and worth looking into ThatRatRodProject 1 Quote Link to comment Share on other sites More sharing options...

patsbimmer1 Posted November 28, 2016 Report Share Posted November 28, 2016 You can't properly get a good look at the pattern for a cam sensor without a scope. The circuit for a cam sensor is pretty simple so unless you nicked a wire while doing the evap stuff then it was nothing you caused. The signal goes straight from the cam sensor to the ECU so the check engine light is only reporting data that the sensor is giving. I would assume it's either vanos related or the cam sensor actually is faulty. I'd lean towards a vanos solenoid issue. Quote Link to comment Share on other sites More sharing options...

B C Posted November 28, 2016 Report Share Posted November 28, 2016 I only ask if an oil change was recently performed because i recently heard of someone discarding an important piece of the oil filter assembly while doing an oil change. Its a frequent enough variable so i thought id ask ThatRatRodProject 1 Quote Link to comment Share on other sites More sharing options...

patsbimmer1 Posted November 28, 2016 Report Share Posted November 28, 2016 More get dirty but they also fail. Neither would surprise me. Quote Link to comment Share on other sites More sharing options...
dastuz Posted November 29, 2016 Report Share Posted November 29, 2016 I know I'm late to the party and this recommendation is also potentially late... I know on my S-motor I replace the micro filter on my Vanos unit roughly once a year. It's super cheap, super easy to do, and I know a few people who have had a lot of luck with that preventing Vanos issues. $0.02 Quote Link to comment Share on other sites More sharing options...

ThatRatRodProject Posted December 1, 2016 Author Report Share Posted December 1, 2016 Well I went threw cleaned everything rest the codes. Drive about a 175 miles and SES light comes back. Plug in the scanner and it's the secondary air bank one and secondary air bank two. I have replaced the smog pump. Checked the evap valve with a vacuum pump. It was between 15" and 18" of vacuum so that's fine. So I then checked the vacuum control switch. No vacuum. Replaced the line and the switch. Still no vacuum. So next step was I check to see if I was getting power at plug for the vacuum control valve. There was power at the plug. I then tested the valve it self ran power to the control switch and the valve opened. I blew in one end air came out the other. Then I put it all back together and check it again this morning. Still no vacuum. Yes I check the fuses. Any help would be great. Good thing no more cam sensors check engine light.

Daggerty Posted December 1, 2016 Report Share Posted December 1, 2016 Are you checking for power by grounding it through the circuit? Quote Link to comment Share on other sites More sharing options...

ThatRatRodProject Posted December 2, 2016 Author Report Share Posted December 2, 2016 Are you checking for power by grounding it through the circuit? No exactly sure what you mean. Grounded to the chassis or to the plug. Sent from my iPhone using Tapatalk Quote Link to comment Share on other sites More sharing options...

Daggerty Posted December 2, 2016 Report Share Posted December 2, 2016 What power reading are you getting through the plug. when testing vacuum are you using your vacuum pump to build the vacuum in the system, or just to read it? Quote Link to comment Share on other sites More sharing options...
ThatRatRodProject Posted December 2, 2016 Author Report Share Posted December 2, 2016 I just took everything apart and put it back together. And the vacuum line was pinched on the valve cover everything is working correctly now. Sent from my iPhone using Tapatalk B C 1 Quote Link to comment Share on other sites More sharing options...
