Details: 2003 Honda Accord Coupe EX 2.4
I cleaned the air induction by pouring in Seafoam Brand (Cleans Well),
so I had to remove the hose last month and for some stupid reason I
forgot to plug the TPS back in. I just noticed this today, as I was
going to replace the TPS thinking it was bad, as my check engine light
is on. I noticed right away when I located the TPS that it was not
even plugged in... So I plugged it back in and still the check engine
light is on.
Last month there was no check engine light on.
So I can scan for engine codes, I purchased this product named AutoTap
Express, you plug the device into your cars computer and then run
software on your laptop, kind of like what dealerships use and you can
read engine colds and do other things. When I checked what the check
engine light codes were I got this.
P0420 - Catalyst System
P0171 - Fuel TrimSystem Loan Bank 1
P0122 - Throttle Position Sensor Circuit Low Voltage
My question is, by forgetting to not plug the TPS back, did I damage
my car? I have been driving it without the TPS plugged in now for a
month. I have noticed that the car burns a lot more gas than normal
and when idleing you can smell the gas, as if it is not properly being
burned correctly. Also, by not having the TPS plugged in on the top of
the TPS to the Engine, would this cause the TPS to go bad?
