p0132, p0202, p0123, p0135, p0138, p0122, p0700, p1594, p0740 all displaying on code reader for jeep cherokee. Jeep runs very hard, back fires and sometimes stalls. Could this be a computer problem? Anyone have any ideas?

P0700 InternalTCM
P0132 O2 Sensor 1/1 Circuit Voltage High
P0202 Injector #2 Control Circuit
P0122 Throttle Position Sensor #1 Voltage Low
P0123 Throttle Position Sensor #1 Voltage High
P0135 O2 Sensor 1/1 Heater Failure
P1594 Charging System Voltage Too High
P0138 O2 Sensor 1/2 Circuit Voltage High
P0740 Torque Converter Clutch, No RPM Drop @ Lockup

 

It could be, but if your Jeep is starting and running, I would say it is less likely, as PCM failure more often means it wont

I would follow the procedure to reset your PCM

In addition, search this forum for threads on multiple codes

further, make sure your battery, terminals, GROUNDS and alternator voltage are all ok

it would be prudent to list up the meaning of each code, as we dont wish to look them up

 

"We" love to look things up!

After refreshing all connectors (see cruiser's post on grounds http://cruiser54.com/) examine the harness for damage, particularly the O2 sensor wires where they are near the exhaust system. Check battery cables carefully. Got a multimeter? Got an FSM? This site has 97 and 00 so that should provide testing information for the sensors:

Clear the codes and see what comes back.

 

What kind of code reader do you have? Can you monitor sensors in real time?
