My Pontiac vibe 2006 is showing PO6006, PO6007 code does anyone ha be any idea what it means


P0606 , P0607 ! no such codes P06006 or P06007
DTC P0601, P0602, P0603, P0604, P0605, P0606, P0607, P1600, P1621, P1627, P1680, P1681, P1683, or P2610
DTC P0606 Control Module Internal Performance
The DTC P0606 and P2610 set when the powertrain control module (PCM) has determined that the control module has an internal fault. The PCM performs continuous self checks of all internal circuits. There are 2 central processing units (CPU) within the control module. If the outputs from the two CPUs deviates from the standard level, a DTC P0606 sets. The control module has several internal clock or timer circuits. The DTC P2610 diagnostic monitors the internal timer circuit responsible for the ignition OFF operation of the evaporative emission (EVAP) system vacuum leak pump. If the there is an error in the control module timer, a DTC P2610 sets.

My car won't start and is showing a p1000 code . What does this mean?


P1000 is a manufacturer specific fault code:

Ford P1000: OBDII Monitor Testing Not Complete.
Jaguar P1000: Engine control module (ECM) - internal error.
Kia P1000: System diagnosis incomplete.
Land Rover P1000: Engine control module (ECM) memory erased - no codes stored.
Mazda P1000: OBDII Drive Cycle Malfunction.

So depending on the manufacturer of your car would depend on the meaning of a P1000 code!

P1621


Trouble code P1621 means: Engine control module engine immobilization input circuit malfunction The Transmission Control Module (TCM) contains various types of memory to gather and share information internally. At shut down, the TCM stores information in memory to prepare for the next ignition cycle. When the TCM cannot communicate internally, DTC P1621 sets. DTC P1621 is a type A DTC.

DTC PARAMETERS
DTC P1621 will set if the TCM cannot communicate internally for a proper shut down.

DIAGNOSTIC AIDS
The suggested repair is TCM replacement. Remember to program the replacement TCM with the correct software and calibration.
however Ive know loose positive battery cable to toss out that code, so check your connections

I have a 2001 pontiac sunfire the check engine light is on. when someone tried to reset it this code came up P1621 what does that mean?


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.

95 jag problem diagnostic code is p1621 anybody know


The code means the engine control module imobilisation function is active.
can you describe what the car is doing and after you scanned the code did you try to reset it?
If so and there is no difference it may be a dealer reset only and you may have a bad ecu (water ingress?)

Jaguar x300 central locking problem


If the locks are working whilst you are driving then more and likely it is the actual door lock assy that is bad. the solenoid go bad and can cause erratic operation. But unfortunately they are only available with the whole door lock/latch assy.
I would disconnect the drivers and see if the problem still exists.
