Have Toyota Questions? Ask a Mechanic for Answers ASAP
Poking around, did you stick something into a fuse block, or wire, or connector if so, what?
Based on this information you should be able to just perform a reset to resolve this. Try disconnecting both battery cables for 15 minutes then hold them together for one minute, then reconnect. Let me know those results. If that fails then we have to start diagnosing the 0453 code.
You want a excellent 5 star answer & I would like to be rated the same for providing it. Consider I don't know your skill level & I can't see, smell, hear, or touch the vehicle. It may take a few back and forth replies. Try your best to respond with good detail so I can do the same. I normally log in at 3pm and work late. A rating is required. Your rating me, what I type. I am not an employee of this website, nor have control over the fees or the time it took to get a response. If you rate negative or not at all you still paid, but I get nothing. I want you pleased with me and my efforts, so let me know if your experience here has come up short.
The only things that can buzz in the transaxle are the solenoids.
We can diagnose the 0453 EVAP pressure sensor concern but its not going to address the no start issue. Use the diagram below for the start circuit.
With the key on, the starter relay removed, and a paper clip jumped from relay pin 3 to 5, does it crank and start?
Its in the fuse box under the hood, its black and square.
Below is an image.
Great, that means the relay is just missing one of its inputs That is going to be the power when trying to start at pin 2. At the park neutral position switch on the transaxle. Leave it plugged in and slide 2 paper clips in beside the red and green wires. OHM test across them. In P and N you should get a closed circuit and open in all other gears.
I can not phone text images from computer screen.
The jumper is only for cranking the engine. Once started it has to be removed or the starter will stay engaged. Yes you still need to verify the PNP switch is showing park and neutral. If not it will not crank with the relay installed and using the key.
You can unplug the PNP and test it with OHMs. If you can not squeeze a paper clip in beside the PNP switch wires to touch there pins so you can test the signal then try a sewing needle. Does your car have the smart key setup?
Great, the PNP is good,
Does your car have the smart key setup?
Use the link below.
You want no resistance in P and N that means there is continuity, power is able to flow through.
A cut wire tested at both ends will show OL out of limits, alot of resistance
A damaged wire or one with corrosion making poor connection will have a number reading like 0.129164, thats resistance
A solid undamaged wire will show 0.0 no resistance.
You want to see 0.0, power can flow in and out of the PNP in P or N.
Unplug the PNP and jump across both wires in and out of it for the starting circuit using a paper clip. Then with the relay installed try to start it. If it at the least cranks, then the PNP is to blame.
Since the jump to bypass the PNP resulted in it not cranking, that means no power is getting from the ignition switch to the relay. So next is to check power into and out of the ignition switch.
Glad you got that resolved. I would need the trouble codes stored to diagnose those other issues.
I have been informed, this new concern with the transaxle is not related to the original issue. This post needs to be rated and a new post opened for this trans code and concern.
Thats possible, but I am not allowed to post diagnostic help on new issues that arise. I have to follow the rules of the website. I could though answer through the additional service offer I sent you.
It seems your not pleased with me, nor plan to compensate me for helping. I will opt out and let someone else try. Best of luck sorry you feel I am to blame for your car being broken and thanks for letting me try.
