    check engine light has been on for a long time. Was told by reputable repairman that no harm will be done to engine. It will go off after extensive highway driving.

Chrysler P0560 code

Generic OBD Error Code Details for P0560 System Voltage OBD II Code P0560 refers to
The battery supplies electricity to the ECM even when the ignition switch is OFF. This electricity allows the ECM to store data such as DTC history, freeze frame data, fuel trim values and other data. If the battery voltage falls below a minimum level, the ECM will conclude that there is a fault in the power supply circuit. The next time the engine starts, the ECM will turn on the MIL and a DTC will be set. SymptomsPossible sumptoms of OBD code P0560
- Engine Light ON (or Service Engine Soon Warning Light) - Slow engine start - Low battery power CausesPossible causes of OBD code P0560
- Loose or missing alternator drive belt - Faulty alternator - Battery defective - Open or short system voltage circuit The Error code is generally activated on detection of the following conditions: The P0560 code is detected when there is an open in ECM back-up power source circuit

What is check engine code p0135

Reasons are:
HO2S no. 1 heater circut is open or shorted
HO2S no. 1 is defective
Defective ECM

Using a scan tool, read freeze frame data. Freeze fram data records engine conditions when a malfunction is detected.

Access ECM behind glove box. Turn ignition on. Using DVOM, backprobe ECM harness connector. If DTC P0135 is set, measure voltage between ground and terminal No. 3 (Blue/Black wire) at ECM harness connector E10. If DTC P0155 is set, measure voltage between ground and terminal No. 4 (Yellow/Red wire) at ECM harness E10. Voltage should be 9-14 volts at each terminal. If voltage is as specified, replace ECM.

If not, Disconnect suspect HO2S No. 1 harness connector. Measure resistance between terminals B+ (Black/Yellow wire) and HT (Blue/Black wire on bank No. 1 ; Yellow/Red wire on bank No. 2) at HO2S connector (component side). Resistance should be 11-16 ohms at 68 degrees F and 23-32 ohms at 1472 degrees F. If resistance are not specified, replace appropriate HO2S. If resistance are specified, Repair wiring between ECM and appropriate HO2S, or between appropriate HO2S and EFI main relay (Black/Yellow wire at HO2S and Red wire at EFI main relay)
