Hello everyone. I’m new here and I need some help. I have a Service Engine Soon light that keeps coming on. The truck has been to the shop twice for this already and Monday will make it the third time. I had Auto Zone check it for me and they say the codes are P1412 and P1415. The truck is a 2002 Discovery II se with the 4.0 V8. Do any of you have an idea on what these codes are or what could be causing them to keep coming up? Thanks for the help.

secondary air systems are not sending correct signals on both banks. Who has been working on it? Need a rover guy

 

P1412 is secondary air system fault on cylinder bank 1
P1415 is secondary air system fault on cylinderbank 2

Sounds like a problem with the secondary air injection system. Possibly the pump is not running when it's supposed to, or there is damage to the plumbing. The secondary air system pumps air into the exhaust manifolds to improve catalyst performance shortly after startup.

 

Thanks everyone. The work has been done at a Dodge and Jeep dealership. But this time I want it to go to the Land Rover place. So on Monday I’m going to go in there and demand ( in the politest way possible ) that it gets over to the Rover dealership. I still have a little bit of warranty left on her so I want it done right before that runs out.
