SOURCE: PLEASE HELP volvo 1998 v70 radio code

You need to call a Volvo dealer. They'll likely ask you for a number on a sticker on the radio itself. You can find that sticker by pulling the radio out (push the 2 skinny vertical "bars" on each side of the radio to pop them out, then pull on them to pull out the entire radio unit).

SOURCE: Error code P0785 on Volvo V70 XC -00. What's the

P0785 - Shift/Timing Solenoid Malfunction (3-2 shift solenoid is not working properly)
P1618 - Diagnostic Trouble Code (DTC) in another control module (in this case, in the Trans Module)

Flush the transmission, get any software upgrades available, reset the adaptors and try it, nothing to lose.

If it doesn't work you will need a transmission. Solenoids are internal, that's what controls the shifts.
They could be faulty or the valve body but one should always do what I said once, if it doesn't fix it, you're looking at a transmission.

The resetting of adaptors is crucial if you update the software. It's basically wiping the memory of the TCU (transmission controller) and teaching it how to shift properly again.

Also could check this TSB...

The reason why I ask, is because anytime there are MULTIPLE transmission solenoid codes, its usually the result of a failed ignition switch. However, since only two codes appeared and were one at a time, I think at this point, its unlikely the result of an ignition switch failure.

P0785 is for the 3-2 downshift solenoid. Either the solenoid is faulty, or something got damaged while the 1-2 solenoid was being replaced. (connector knocked loose, wire rubbing on pan or valvebody, etc...).

The 3-2 solenoid is #394 in the picture below, which is at the opposite end of the 1-2 solenoid.

P0785 is for the 3-2 solenoid and that is 394 in the picture. Is it likely to fix it? yes, but of course I cannot guarantee that it will, sitting behind my computer and never seeing the vehicle.

Hope this helps.

What makes my Chevy malibu 2005 v6 put system code po449 out


P0449 - OBD II Trouble Code Evaporative System Vent Valve/Solenoid Circuit Malfunction Our emissions expert has put together the following information about the P0449 fault code. We have also included diagnostic procedures you can take to your repair shop if the mechanic is having difficulty analyzing the code.
OBD II Fault Code
  • OBD II P0449
Fault Code Definition
  • Evaporative System Vent Control Circuit Malfunction
What does this mean? The evaporative control (EVAP) system captures any raw fuel evaporating from the fuel storage system (e.g. the fuel tank, filler neck, and fuel cap). Under precise operating conditions-dictated by engine temperature, speed, and load-the EVAP system stores and purges these captured fuel vapors back into the combustion process. The carbon canister, which stores the raw fuel vapors, utilizes a vent valve that allows fresh air to enter the EVAP system. This displaces the fuel vapor as it's purged into the combustion process. Code P0449 indicates that the evaporative control (EVAP) system vent valve solenoid is malfunctioning. This can be caused by either too little or too much electrical resistance or a mechanical problem with the vent valve itself. Symptoms
  • Check Engine Light will illuminate
  • In most cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be a noticeable fuel odor caused by the release of fuel vapors
Common Problems That Trigger the P0449 Code
  • Missing fuel cap
  • Defective Evaporative Vent Valve
  • Defective or damaged fuel cap
  • Distorted, damaged or cracked Fuel Tank Filler Neck
  • Torn or punctured Evaporative system hose(s)
  • Defective Fuel Tank Sending Unit gasket or seal
  • Split or damaged Carbon Canister
  • Defective or damaged fuel tank
Common Misdiagnoses
  • Fuel cap
  • Evaporative Purge Valve
  • Evaporative Vent Valve
Polluting Gases Expelled
  • HCs (Hydrocarbons): Unburned droplets of raw fuel that smell, affect breathing, and contribute to smog
