2006 V70R (automatic) throwing 19 error codes

thenickdallshow · Post by **thenickdallshow** » 10 Apr 2019, 23:34

A couple of weeks back I had been driving for about 10 minutes, when my car started chugging/hesitating on acceleration. After driving for a few more minutes, the CEL came on and the message center flashed the messages 'anti-skid service required' and 'engine maintenance required'. This was accompanied by the transmission locking into third gear (I'm assuming some sort of limp mode) and the 'D' on the gauge cluster being replaced with a '-'.

I let it sit for about 10 hours and had the same occurrences on the way home, but the issue was so bad that it stalled three times at stop lights. I took it to a trusted (but technically lacking) mechanic who told me to take it to the dealership. The battery and alternator tested fine, but there were 19 codes on the OBD scanner, seen below.

I am at a TOTAL loss and have absolutely no idea what to do. Any help or guidance would be amazing.

P0240
P0101
P0089
P1719
P0101
P0170

First step is to get a scanner and clear all those codes and see what comes back, and when.

You are going to need 5-10 hours of researching to troubleshoot this successfully ifVolvo is new to you.

How many miles are on it and what’s the service history?

You might try the battery disconnect reset as well.

Thanks guys. I should have mentioned that I have indeed cleared the codes twice - once through a scanner and once through a battery disconnect. Issues persist as described shortly thereafter.

Im not knowledgeable with your year, but you would have to assume bad engine ground, bad ECU, bad alternator. I know you checked it, but a bad alternator will light the dash warning lights up like a Christmas tree. You can have 14 volts but it may be AC if the diodes are bad, or it could be shorting if the bearings are gone. has it been noisy?

Can you do the ad,in work of googling each code with the word Volvo, Andy then putting the code description NextDoor to each code in a new post?

Once we can see the whole story we can offer advice on what to tackle first. I’ll guess there are only 2-3 faults , not 19

Sorry abscate, probably should have included those descriptions first. Here they are:

P0240 - Turbocharger/supercharger boost sensor B circuit range/performance
P0101 - Mass or volume air flow A circuit range/performance
P0089 - Fuel pressure regulator 1 performance
P1719 - Skip Shift Solenoid Circuit
P0101 - Mass or volume air flow A circuit range/performance (not sure why this was displayed twice...)
P0170 - Fuel trim (bank 1)
810D - Power supply (5-volt)
126B - Boost pressure sensor
310C - Misfire, at least one cylinder
315C - Misfire cylinder 5
313C - Misfire cylinder 3
3110 - Misfire cylinder 1
121B - Mass airflow sensor
2900 - Fuel pressure
212D - Long term fuel trim, bank 2
21ED - Long term fuel trim, bank 1
0032 - HO2S Heater Circuit High Voltage Bank 1 Sensor 1
0A31 - No DTC definition found
0101 - Communication between control units

Very confusing. There is no skip shift solenoid on Volvos.
There is no bank 2 on a 5 cylinder.

I am thinking the scan tool is not interpreting Volvo codes correctly.
Some of those alphanumeric strings can exist with a three character module acronym in Volvo code language. Some of the strings can exist in multiple modules.

I am scheduled to take it to the dealership in two days for a VIDA scan. Hopefully that will shed a bit more light on it, and I will update when I find out more. Thanks!

Skip shift solenoid.. Generic OBD codes get a little 'lost in the translation' sometimes.. especially if the definition was pulled off a website linked from a search engine.

You said the issue is intermittent? Meaning sometimes you can restart the car and it'll run/drive fine for at least a short period of time before going haywire again, correct??

If that is the case first thing I would rule out would be the engine management system relay under the hood. And while you're at it make sure every fuse/relay on that panel is pushed down/seated fully. I am aware of a friend's coworker whose V70 was acting like this and it turned out one of those relays had worked itself partway out/wasn't fully seated down into the panel. He didn't say exactly which relay it was.

If those are all ok you're probably looking at a bad ground or power connection somewhere. Unless you're experienced/already highly familiar with the P2 Volvo electrical systems you might find letting the dealer sort it to be your better/faster option.
