What does DTC P1621 mean on a 2001 Chevy cavlier mean and how to fix it?
A vehicle control module (VCM) or powertrain control modules' (PCM) electronically erasable programmable read only memory (EEPROM) contains data essential to running the engine and transmission. The VCM/PCM stores critical preprogrammed data within the EEPROM, this data remains even if the vehicles' battery is disconnected. At power up the VCM/PCM checks the integrity of this data. If the checksum of the EEPROM does not match a predetermined value, DTC P1621 will set. The DTC will also set if the VCM/PCM is unable to correctly read or finds corrupt data from the EEPROM. GM recommends testing/replacement of the VCM/PCM using required equipment by a qualified technician for this type of VCM/PCM memory performance fault condition. I hope this has shed some light on the matter of P1621 GM manufacturer specific diagnostic trouble code (DTC). Answer: This answer was heplful but I had the same problem on my 99 cavailer and i went to the junkyard got another pcm for $50 and got it installed and reprogamed for only $174 (including taxes) that's your best way to go about it...unless you have the speacial comptuer to program the pcm to your vehcile...which is unlikely.

I believe it means your engine is misfiring on bank one which I believe is the left or drivers side bank. Check your spark plugs and wires and see if you see any problems.
What does obd dtc p1402 mean on 1998 dodge 5.9 magnum with no egr valve?
I would double check that that is the actual code stored in the PCM. That is a code for EGR and you are correct that you do not have EGR.
