P2441: AIR System Switching Valve Stuck Closed Bank 1
A generic powertrain (engine and transmission) trouble code, same meaning on every brand.
Yes - a valve stuck closed mostly means the clean-air system cannot do its cold-start job. Emissions test failure is certain; danger is not the issue here.
Symptoms
- Check engine light
- No pump noise at cold start where it used to be audible
- Failed emissions test
- Possible reduced power mode on some trucks
Likely causes, most common first
- Switching valve corroded shut by moisture
- Carbon sealing the valve
- Vacuum or electrical control fault at the valve
- Pump failure upstream reducing flow
Read P2441 yourself before paying for diagnosis
A basic Bluetooth OBD-II scanner ($20-40) plugs into the port under the dashboard and shows this code with live sensor data on your phone - useful both for confirming the fix and for talking to a shop from an informed position.
What is going on and how it gets diagnosed
P2441 closes the loop on the secondary air story: where P2440 complained of a valve stuck open, this code finds the bank 1 valve stuck shut - the system cannot inject its cold-start air at all. The moisture-and-corrosion mechanism is the same disease in the opposite direction; condensation rusts the valve into whichever position it happens to favor.
The consequences are purely regulatory rather than mechanical - converters take longer to light off, monitors never complete, inspections fail - though some truck models respond to air-injection faults with a precautionary reduced-power mode that makes the repair feel more urgent than the emissions story alone. The economics repeat from the stuck-open pages: valves corroded by a moist system rarely fail alone, so a quote covering the system rather than one valve, plus a check for goodwill coverage on affected model years, is the honest path.
Repair options and cost
Typical US independent-shop ranges, parts and labor. Dealers run higher; regional labor rates vary.
Owner reports mentioning P2441
“I was driving my truck on the highway and it slowed down severely and I was concerned about getting into a wreck. I went to a mechanic and had a p2441 code”2011 Toyota Tundra · May 2019
“Codes P1442, P1445, P2441, P1441. Had to install a new Secondary Air Injection System. Defective emissions system. I (service station) mistakenly bypassed the system in order to save several thousand dollars when the SAIS was known to be defective in these vehicles.”2007 Toyota 4RUNNER · Mar 2019
“Air injection pump and air switching valve assembly. Vehicle generated an obd code of p0418 and p2441. Vehicle only has 66k miles. Vehicle is unable to accelerate to normal driving speeds, very sluggish. Cost to repair is $2k. This is the same problem on 2012 toyota tacoma and experienced on 2013 - 2015 being reported. This is dangerous to drive!”2014 Toyota Tacoma · Jan 2019 · 66,000 mi

“Multiple subaru's with turbo engines are experiencing the p2441 cel code which is an issue with secondary air valves being stuck. This is part of the emissions system and not powertrain so warranty doesnt cover beyond a certain timeframe. This issue has also been occuring over the past decade, with expensive cost to fix >$1200 for a valve repair. It appears even with proper maintenance the failure of this part is unpredictable. Subaru of america refuses to acknowledge the frequency of this failure.”2011 Subaru WRX · Aug 2017 · 97,000 mi
“Check engine light on, trac off light on, engine power weak check engine code- p2441. This has been a common issue with toyota suvs, and trucks! Car is put into limp mode. Extended warranty on tundra with same part problem. Not tacoma. Shameful and dangerous for tacoma owners.”2012 Toyota Tacoma · Jul 2017 · 61,000 mi
“Secondary air injection error codes p2440, p2441,p2442. Loss of power due to air injector stuck. Vehicle will not accelerate beyond 20-30 mph. This is an emmsisions requirement but warranties on tacomas will not cover beyond 3yrs/35k miles. Tundras have tundras have same known issues and toyota incrwased warranty to 10 yrs/150k miles. Sudden loss of power is also a safety issue while driving on highways. Owners are paying thousands in repairs for something that should be covered under warranty.”2012 Toyota Tacoma · Jul 2017 · 69,000 mi
“My traction control light has came on and stays on, my vsc light continuously flashes. The code that it keeps sending is p2440 and p2441 (secondary injection). I had went overseas with the military for two years and came back last year to change the battery and this started. The truck only has 75,000 miles. This is all the time, doesn't matter stopped, going, high speed, low speed.”2007 Toyota Tundra · Feb 2017 · 73,000 mi
“Tl* the contact owns a 2011 toyota tundra. While driving at 60 mph, the vehicle decelerated and the engine and slip differential lights illuminated. The vehicle was taken to the dealer, where it was diagnosed that water intrusion codes p2440 and p2441 needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was 90,000.”2011 Toyota Tundra · Jul 2015 · 90,000 mi
“Secondary air injection pump is making a loud humming noise at a cold start up. I pulled the error codes. P2441, p1445 and p1442. I contacted the toyota dealership and the cost for the new pump is $2300. That is such a big expense for a 7 old truck and to have it repaired will be more than $3200. I believe that the design and construction of the part are flawed and replacement should be covered by toyota. *tr ## VIN failed ##”2006 Toyota Tundra · Feb 2013 · 120,020 mi
“The fault indicators came on and the error code p2441 was present both at the first occurrence and at the second occurrence at 105,000 miles. At the second occurrence the price for fixing the problem was set at $2123. At this price and guessing at the price of other parts the car's replacement value should come to around $200,000. This is a common problem pervasive to all subarus, not just foresters, featuring a turbo charged engine. *tr”2007 Subaru Forester · May 2012 · 67,893 mi
