I have an engine management light come on - tested - came up with a code PO410 - what is the next step?

Google your codes & read up

Type: OBD & your codes

The way you work on any vehicle ,is to have factory service
manuals with trouble charts to follow

You need a professional scan tool, almost always ,to get not
just Generic but Enhanced codes

You have to road test to gather & look a all Data

You have to review the data & come up with your component
testing strategy, just to find a problem,anything,correct it &
continue on

Do you have a code reader with you?

It is a common misconception that the instrument cluster self test gives DTC's for the engine management system, it provides cluster related DTC's on test 10 of the cluster self test, DTC should be displayed above the code, these will be displayed at 1 second intervals, once you press OK again the cluster will scroll to the next test, the format of the codes shown in the cluster is designed for Ford engineering and can only be translated into usable codes by Ford IDS.

The only way to find out why the engine management light is on is to have a scan of the engine management control module carried out using an appropriate code reader, this will give you the standard EOBD codes for example a catalyst efficiency code would show P0420. If you want to do this on a DIY basis then cheap code readers are available on the internet for around $75.00, these code readers also reset the light after the fault has been fixed. if this was helpful please leave me good feedback

code po410 on a 2004 gmc envoy is that there is a problem with the secondary air injection system, you will need to check the fuse located in the engine compartment first, the next step is to start the truck cold and listen for the air pump to turn on for a few seconds, this will sound like a jet engine but not that loud, after it runs for 5 min and you dont hear it then you may have a bad pump which is located under the driverside on frame but if you hear the pump then you may have a bad valve, this valve is located on the exhaust manifold area and has a hose from the pump to valve, remove the hose and check for water, drain any water in the hose, also remove hose at pump and drain, the most common cause for this code is the valve is not opening and the air pump gets water inside and goes bad, thats the po410 code. a quick note; if fuse is blown look under truck near pump and check relay as it fills with water and blows fuse, if this is the case replace relay and blow water out of connector.good day.

Hey; Code 307 is a code for misfire on cylinder #7. It could be caused by bad spark plug, ignition module. If engine has a miss then I would replace the spark plug first. If that don't fix then it will require further diagnosis with a scan tool. Code PO410 is for the secondary air injection system. Make sure the vacuum hoses going to the valves on the front and rear cylinder banks are connected and the hose(s) not damaged. Also make sure the solenoid is connected both electrical and vaccum' Maybe this will help

P0410 - Secondary air injection system.

This has to do with the secondary air pump system, this system is used at cold start-up and involves three components; air pump, solenoid valve and a relay. Many times the valve becomes stuck or clogged, the relay has also been known to fail.
