You might find that the throttle sensor which is electronic and part of the accelerator pedal has become unresponsive due to lack of use.i had this problem with a ford maverick which had been sat idle for a few months. And this caused the engine management light to come on and throw into limp mode.my cure was to press the pedal up and down quite hard with the engine switched off.also did this to the clutch pedal.cured the problem but every so often for the first year of regular use it would repeat.so I just pumped the pedal fully up and down whilst engine was off.no more limp modes.

    I have the exact same issue with a 2002 V70 XC 2.4L Turbo. Did you ever solve this problem?

Check vacuum hoses to MAP sensor. They can get porous after a while. Also check hose to EGR valve.

Check the actual ohm readings for tps sensor to manufacturer specs. Sounds like the tps sensor is out of range. Sometimes the o2 sensor gives a false reading to the ecm which causes the tps malfunction. Doubt seriously if it electrical short. Bad ground maybe.

With both codes pointing at TP sensor, I'd certainly take the time to replace it, as well as make sure connections to it are clean, and good. Chances are, you won't be able to take part back anyway. As far as exhaust goes, if it's leaking in the right places in may cause improper readings at sensors downstream, but if not obvious leak, I wouldn't be concentrating in that area right now.

Possible problem with the alternator not putting out enough voltage. I had the same problem with my 2002 XC70, putting in a new alternator fixed it. I used a local mechanic who I found on the car talk web-site. Low Cost Volvo parts can be purchased at FCP Groton.

Linc LS v8 05 will not excellerate only idle,scan code #p2104, p2111, what's going on.


code p 2104 refers to throttle actuator control(TAC) system--forced idle mode===causes ---wiring--TAC motor--ALL sensor--ECM
codes p 2111 refers to throttle actuator control (TAC) system--actuator stuck open====causes --throttle body--throttle valve tight tight/ sticking
also refers to TAC system --circuit malfunction=== causes wiring short to positive ---short to ground ---TP sensor ---ECM
also refers to brake vacuum---implausible signal====causes ---wiring--- vacuum sensor--- mechanical fault

What do the codes P0507, P2111, P2135 and P0221 mean


P0507 is Idle Control System RPM too high - I bet your idle is around 1500-2000 rpm, right? That could be the idle air control valve, or something as simple as a mass airflow sensor cleaning (get the specific spray for it, not just WD40 or something).

P2111 - Throttle ActuatorContro System. On a 2004 you may have to clean the throttle body. It's not THAT big of a deal, but run by the dealer and get a new gasket first.

P2135 & P0221 - I think that's the Throttle Position Sensor/pedal switch.
Maybe someone messed with the intake on the car and knocked some wires off. Check the throttlebody connector that it's seated all the way in.

I'd start by disconnecting the battery overnight or pulling the fuses for it (remember to let the car sit for 15 minutes after ignition off before pulling the negative cable, then turning the ignition to position 2 before you reconnect it).

You might want to call a local Volvo shop (or dealer) with a VIDA/DiCE connection to get a proper read on the codes.

I wouldn't think catalytic converter, without it giving some indication that it was going bad, but without testing it is hard to say.
When it cranks and won't start, check for battery voltage to the coil on the dark green wire, with key ON. If you have power at the coil, it might be a bad coil. If no power to the coil, it could be a Crank Position Sensor or the Cam Position Sensor inside the distributor. If one of those is bad, it can stop the computer from sending power to the coil.
Good luck.

The following diagnostic codes P2104, P2111, and P2112 the engine failure mode appears car wont move turn it off and on again and its fine with just the check engine light Happens several timesaday now


all the codes point to throttle body. clean throttle body, especially around throttle plate. check for loose wires, if problems persist. replace throttle body. p2104 is tac system forced idle, p2111 is tac system stuck open, p2112 is tac system stuck closed. clean throttle body good, and see if this fixes it. then go from there. have a good day !!

I have 3 codes from my scaner p2111 p2112 p2238


P2111 - Throttle Actuator Control System Stuck Open.
P2112 - Throttle Actuator Control System Stuck Closed.
P2238 - O2 Sensor Positive Current Control Circuit Low Bank 1 Sensor 1



For the P2111 & P2112 you will need to replace the throttle body this can be pricey since the TAC is built into it. Try cleaning it good and see what happens. This can also trigger the P2238 code if its dumping fuel.
For the P2238 check the connections on the o2 sensor or replace the upstream o2 sensor that should correct it.
