code po200

[leadfoot3]

I have a check engine light ..........took it to auto zone to down load the error code...........m24 workhorse, 2007.

aa1 open or shorted fuel injector
aa2 open or short in electrical circuit
aa3 high fuel pressure-pressure regulater defective-fuel return line blo
cked
aa4 check tps and circuit for failure

my question is ......is this right for the m24 chassis or is he giving me the code for a chev truck, or is there a differance. the coach only has 5000 miles on it.

ok ......I pulled the engine cover and started looking around, one injector cap was not quite on. pushed it about and 1/8 and it snaped on the injector. Started the engine and I could hear a spark at a plug wire, melted boot I guess.....new wires are in order, with insulaters. Do you think this could have caused the code?

most likely thats your problem,did you google the code?

Absolutely It's a chain reaction with the smog system when one thing goes out. I had a very similar event on my Ford V10.. it has a coil on each plug and one had a broken hold down tab... bounced off (thank you California Highways).
It will take several starts and many miles for the error to go away once it's fixed. Mine went away after a 600 mile trip.

thanks Rick......I'm going to change plug wires with after market heat shields and see what happens. after googling, it seens if it was an individual injector the code would indicate so..............still wondering.
thanks for the help.
