I have a 1997 dodge stratus what is po 153

thats about the ASD relay. the automatic shut down relay. that gives power to the computor

This is an anti-theft feature.
Check with your local dealership, or call Dodge about the code.
If you bought the car new, the code maybe with the original paperwork.
Not sure if there is a charge to get the code.

have you tried typing in the word obd2 before po 340 in google? usually obd2 website pops up with a complete solution of everything it could be... there is some cars or codes that don't specify as well as they should, so in that case take it to autozone where they do free code reading

Manifold Absolute Pressure/Barometric Pressure Circuit Range/Performance Problem fix this then you can remove the code

PO 340 thru PO344 are cam shaft position sensor issues

That does not tell you what is wrong or to replace anything

Have it diagnosed at a repair shop

A sensor could fail & it more than likely is just
reporting other issues you have to have resolved.

PO -133 O2 Sensor Slow Response

Po -- 153 same thing


Check for vacuum leaks --every where

Clean MAF Sensor -CRC MAF Cleaner

Replace the 2 --front O2 Sensors, if over
100,000 miles on them The ones closest to motor

Use the OEM Type not the cut & splice
universal junk

NAPA can order them
Should be Bosch or NGK

Codes do not tell you anything about what is wrong
or what to replace.

PO 134 = 02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 1 SENSOR1)
PO 153 =02 SENSOR CIRCUIT SLOW RESPONSE (BANK 2 SENSOR 1)
PO 154 =02 SENSOR CIRCUIT NO ACTIVITY DETECTED (BANK 2 SENSOR 1)
PO 155= 02 SENSOR HEATER CIRCUIT MALFUNCTION (BANK 2 SENSOR 1)
PO 171= SYSTEM TOO LEAN (BANK 1)
PO 174= SYSTEM TOO LEAN (BANK 2)
I WOULD SAY YOU HAVE FAULTY OXYGEN SENSORS CAUSING THE ENGINE TO RUN TOO LEAN REPLACE THEM AND YOU SHOULD BE BACK IN BUISNESS

sensor on the tranamission needs replaced

your map sensor is either unplugged ,defective, or you have vaccum leak
