not B161 or P1618
are you sure, it matters.
this means the battery was low
the battery was disonnected
or while cranking at -40F starter overloaded a weak or discharged battery.... (heard the starter run slow, did you?)
it means battery voltage discover too low for any reasons.,.

07 Aveo error codes p2110 and p161b. Can this be a bad battery?

code p2110 refers to throttle actuator control (TAC) system-forced limited rpm mode (limp mode)===causes wiring--tac motor- APP sensor--ECM
it also refers to heated oxygen sensor(HO2S) 1 bank 1 implausible signal===causes wiring .--short to positive-- short to ground--HO2S sensor---ECM
Check/replace the HO2S sensor and check the APP sensor and TAC motor.

2009, what engine there, and transmission?>
gas engine, or diesel and what size engine,?
in what country? must i guess, that too?

P means power train.
1xxx are factory codes, 0xxx are fed standard codes.
so that means, only jeep books are accurate here.

where did you see that, (in the cluster) ???????????
or someone scan tool> or someone yelled it over shoulders, and said it wrong./????????????
was it really? and 8? or b? (kinda matters, no?) accurate inputs.
P161b ( see how easy it is to get the code wrong)?

rumor has it as
P161B: Battery disconnect/TCM internal.

clean the battery terminals,
or battery weak, voltage not 12.6vdc rested
or alternator dead, and not charging battery.

to find it, login to Mitchell.
and see all codes

or you disconnected the battery while key was on?
or failed to clear all DTC first
then see if the code comes bacK>?

Help.. I have an 2002 dodge caravan witha 3.3. The codes pulled from it are P0700and P0605 which i know is with the Tcm but I have no power to the tcm plug unless you take the negative off from the battery...

HI, the actual p700 is an indication of a stored code that exists within the TCM module. The actual code will be the p0605, which is an internal failure alert that exists within the actual tcm module board sector. There may be board level damage to the internal layout which is causing a major short or misdirection or power to the vital circuits needed to provide necessary direction for the transmission. You will need to replace the module at this point. It is not repairable, unfortunately, due to the state of its design. Once it is replaced, it will need to be re-calibrated by a dealer scan tool before normal speedometer function will resume.

In conclusion, replacing the TCM will correct this issue. I would also inspect all connecters for faults before installing the new module.

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

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
