DTC P1599 will set if the PCM has detected an engine stall condition when:
• The engine is in run mode.
• The ignition voltage is present on circuit 439.
• The crankshaft position (CKP) pulses at the PCM are NOT detected.
DTC P1599 is a type D DTC.
The powertrain control module (PCM) has the ability to set a diagnostic trouble code (DTC) if the engine stalls when the ignition has not been turned OFF. This DTC may aid in intermittent diagnosis of a customer complaint of intermittent engine stall. The scan tool Failure Record information can be duplicated under the same stall conditions in an attempt to reproduce the occurrence. Since DTC P1599 is a type D DTC, the PCM will not command the malfunction indicator lamp (MIL) or SERVICE telltale On. This DTC can set due to driver error. For example, a vehicle equipped with a manual transaxle in which the clutch was released too quickly causing the engine to stall, will set DTC P1599.

both codes point to needing a new EGR valve

Check purge valve that could be stuck open

Having codes read is a waste of time, if you don't understand
or work on vehicles

You need a shop to properly diagnose it,you know that

Any codes can be Googled to look them up

Type: OBD & the code

Codes have little to do with replacing parts

No parts get replaced until they are tested & fail a test

Before you replace the sensor, you should check the voltage circuit for the heater. The sensor may be fine and not getting voltage to the heater inside.
The code 1599 just means the engine has stalled at some point. It does not tell you why or how.
I doubt the two codes are related.

CPS is bad

p1599 refers to TPS (throttle position sensor) Stop by a local parts store (Advance, Autozone, etc) and have them do a free fault scan for you.

P0410 Secondary AIR System Performance

P1599 Engine Stall Detected

Leave it to GM to use a computer code to tell you your engine died. The AIR system was a mistake they felt like was best corrected by continuing to use it. The system is similar to EGR function where it injects air into the exhaust for emissions. When it screws up, and it does often, it makes the car run horrible and is usually expensive to fix because the parts are hard to find. I would call a local GM dealer, give them the codes and see what they estimate the cost to fix it is. You might consider trading it in after that.

ok now for starters, we will go with the most probable:P0341 crank position sensor. chances are it needs to be replaced. 2nd your check engine light has probably been on for a while right?! the P0133 is an o2 sensor code and would probably be good maintenance(but get it to run first. 3rd P1599 refers to it stalling out which if it died while running would most likely trigger this. and last but not least either your coolant level switch is faulty or you really do have low coolant. let me know.
