1999 Civic Dx- Codes P0113, P0131, PO132, and P1129; High and low voltage on same O2?
 

EDIT:
Fuse 43 was blown under the hood. Its a 7.5 amp. My EM1 dome light is shorting it out I dont know why.


ANYWAYS, these are the codes I pulled.

P0113 Intake Air Temperature (IAT) Sensor Circuit High Voltage SWAPPED IATS AND FIXED THE PROBLEM.
JK [b]Primary Heated Oxygen Sensor (Primary HO2S) (Sensor 1) Circuit Low Voltage[/b
JK [b]Primary Heated Oxygen Sensor (Primary HO2S) (Sensor 1) Circuit High Voltage[/b
JK [b]Manifold Absolute Pressure (MAP) Sensor Circuit Higher Than Expected[/b

1. Does code 113 with the IAT mean that the IAT sensor is bad? I believe I have a spare.
2. How does the primary o2 read high AND low?? That doesnt make sense.
3. MAP circuit higher than expected?? Do I also need to replace the map?








Sup all

1999 Civic Dx
OE engine (mod wise)
OE P2E ECU

I got state ref'd in CA so I went back to stock. I took off the P28 and threw on the P2E ECU that I bought on craigslist from a wrecked car.
The car turned on first try and everythings fine. Only problem is; its running a little rich (smells like it has no cat, but it has the factory one.), and when I connect a scanner to it, the scanner doesnt read. I took it to Pep Boys for them to scan and they couldnt scan either. The scanner doesnt even turn on so I dont think the OBDII port is getting power.

I looked around and I dont see a fuse for the port. Is there a fuse somewhere else around the car?

Im in Texas right now but I need to go back to California to fix this ticket.

Hood fuse 43

Re: 1999 Civic Dx- It has a CEL, I cant scan it!
 

Which fuse is that? The under hood fuse box isnt labeled by numbers.


Its not the F/I EM fuse is it?

The FAQs sticky at the top has printable fuse box diagrams.


No, but next to it.

Ron, you are amazing with Hondas and I would love to buy you a beer. I just relocated to San Antonio, TX! haha


Can you change the thread title to: "Codes P0113, P0131, PO132, and P1129; High and low voltage on same O2?"

Re: 1999 Civic Dx- Codes P0113, P0131, PO132, and P1129; High and low voltage on same
 

Title changed. Start by resetting the ECU to see whether all codes return.

Re: 1999 Civic Dx- Codes P0113, P0131, PO132, and P1129; High and low voltage on same
 

Appreciate that.


And done.. Only code P0113 returned. I tried deleting it and after 2 seconds it returned.

Something tells me I forgot to reset my ECU when I installed the O2 sensors and I drove rich all the way to TX from CA. fuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuuu

Inspect the IAT sensor and its connector and wires. Is it unplugged?

P0131 and P0505 came on after about 20 minutes of driving.
