Are these 2 codes the same codes that keep returning when it goes to limp mode?
Customer: replied 2 years ago.
Yea the P0202 injector 2 circuit goes on before P0607.
I forgot to mentioned that the P2262
Turbo not detected code comes on randomly for the past 4 month when I use the exhaust break.
Expert:  Robert R replied 2 years ago.
OK, the P2262 is a different issue that is pointing to a turbocharger problem. Usually, a Turbo cleaning will fix the P2262. If turbo cleaning doesn't fix the problem. The Turbo will need to be replaced....
On the P0202 and P0607 there are basically ONLY 2 possibilities. Since you already replaced the Injector and the Valve Cover gasket, the Only 2 possibilities are the ECM and a problem with the Wiring Harness... About all you can do is ohm out the injector circuits to the ECM and if all are ok, the ECM WILL need to be replaced...
Here is the Flow chart for the P0607. I'll round up the P0202 and/or P2262 chart if you need it.
