Typically if you can clear the valve stuck open code after your initial engine warmup for the day and the valve stuck open code does not come back on it is because the air pump is failing. We do have solutions for the code though and would be glad to help you resolve your problem for a fraction of the cost to replace the system. Is the voltage more than 10 V? Other possible causes of this issue would include damaged wiring or connectors associated with the air pump, blown fuses, or a broken serpentine belt. This trouble code is considered moderately serious. The pump is located on the front passenger side wheel well. The computer will then send an error code turning on your check engine light and specifying the failure mode. I have not gone to the Scan gauge thing yet; are these expensive? A mechanic may diagnose this trouble code by checking the condition of the serpentine belt and the secondary air injection pump for any noises.
Don't waste time trying to preserve the plastic clips. The monitors the secondary air injection system and detects malfunction using a pressure sensor located on the air switching valve. Remove the motor from inside the fender well. Another choice, which is also very popular, is to purchase a module that requires cutting and splicing into your factory wiring harness. I'm going to put them back on but wondered if you had any other solutions for my problem or any suggestions that I should try. Check Yes No Replace the secondary air combi valve which has air leakage.
During the winter months this moisture can freeze, causing the air pump to seize up and possibly break. Need help with a P2445 code? It can also sometimes be a damaged pressure sensor but this is usually after the vehicle remains to be driven with a valve that is leaking exhaust which can damage the sensor. Posted on Oct 27, 2014 here is what i found on p1416. Plenty of information is available online regarding this method. Obviously if the fan turns it works move forward. The cost to replace this system at the dealer is ridiculous. Some have suggested taking it to a mechanic, but being a do-it-yourself kind of guy I'd rather pinpoint the problem and fix it myself.
These modules take care of all of this. What causes the P2447 code? Both available kits include a set of block-off plates, which are required to be installed in the system to prevent hot exhaust gasses from reaching the air injection pump s. Again, complete instructions come with the kit. There is a thin metal gasket between the two — it is not necessary to remove this, simply leave it in place. I had to pull off the big plastic guard 8 12mm bolts to get some working room.
It is more often the air pump than the valve. What repairs can fix the P2445 code? This trouble code indicates that the powertrain control module has detected a malfunction with this system on the bank 1 side of the engine. I said thanks, but no thanks. When you turn on your ignition the computer will determine whether or not you've had a failure in one of the 2 air valves or the blower motors. After a few months of testing, the module was complete and ready to sell. This is due to the fact that it can cause the engine to hesitate or stumble during acceleration.
However, before I dropped a bunch of cash to fix it, I decided to order one of the bypass kits for the 4. I took it over to the dealership to get it checked to confirm what my code reader said and to make sure they hadn't left a hose disconnected or something when they did the 90k mile service this service was conducted as a part of the purchase agreement. Failures of these systems has been a big issue on the Tundras. When it does run, it's only for a few minutes until everything heats up. If this fails to help, apply more penetrating oil and start the engine and allow it to get hot 10 minutes is plenty of time. The observes the pressure in the secondary air passage using the pressure sensor located on the air switching valve in the secondary air injection system. Check for poor contact of connector.
A temporary poor contact occurs. The cable is feed through the same hole the outlet tube is in the fender well. The observes the pressure in the secondary air passage using the pressure sensor located on the air switching valve in the secondary air injection system. It only runs when the coolant is below 104 degrees and the air temp is above 40 degrees. The block-off plates will replace the existing metal gaskets found between the air tubes and the exhaust manifolds. This can cause overheating of the air pump which can potentially cause further damage to the electrical portion of the air pump system. So while I haven't seen many posts about this on mud, there are others out there that have had this issue on their 100-series.
It's more than I'm going to do myself but it looks like a pretty straightforward repair for most shops. All three methods above are considerably less than the dealer repair, but keep in mind that bypassing mandated emissions is illegal on public roads. The pump is bolted on using three 12mm bolts. It's an emissions system and has absolutely nothing to do with the function of the engine. The sensor detects an exhaust pressure in the secondary air passage. This may lead to a clogged catalyst. Yep, the dealership said water and small leaves are ingested and destroy the pump.
I removed them and tested them both. Measure the resistance between secondary air pump relay terminals. The exhaust emissions will be affected and will cause the vehicle to fail emission testing. You just unplug the air sensor harness on the intake and plug the module in the middle. Common mistakes when diagnosing the P2445 code A common mistake that can be made when diagnosing this issue is to remove and bypass the secondary air injection pump. Repair the battery short circuit in harness between Replace the secondary air pump relay secondary air and secondary air pump connector terminal.
