Hi Guys. Tracie's 1998 Accord Coupe is throwing a check engine. The car stalls on idle. She just came back from Autozone. They indicated these codes:

P0108 3 Manifold Absolute Pressure (MAP) sensor circuit low/high voltage
P1166 41 Primary HO2S (No. 1) Heater System Electrical
P1167 41 Primary HO2S (No. 1) Heater System

Seems to me after doing some googling that the O2 oxygen sensor is bad. Should I just purchase one at Autozone or should I hit up Honda parts (Get a denso or OEM)?

Autozone about $73
eBay about $45-50
Denso about $80-90

I also need to know which O2 is defective. there are two. primary one is in the exhaust manifold (front of motor), the other is in the catalytic converter (under the car). With those 2 codes are they both bad? I am leaning toward the primary one off the exhaust manifold.

 

Scratch that I will get an OEM one. After calling the Honda parts at Curtis Ryan they wanted my VIN. I guess there are different ones depending on when the car was built.

Although I am hoping it will clear out the P0108 which points to a MAP sensor. Those can't be cheap?

 

wonder with you can whack the map sensor like the ones on the s2ks

 

Hmm more google info - the code P0108 is a Manifold Absolute Pressure/Barometric Pressure Circuit High Input

This means you have a bad map sensor. It is located on the throttle body and the part number is C7004-183531. It cost about $70.00

Looks like I will be purchasing a MAP Sensor and O2 Sensor!

 

When was the last time the ignition cap/rotor were switched? Plugs?

I got O2 problem codes on a friend's Civic....she took horrible care of the car and the faulty ingnition caused O2 sensor problems.......I know your maintenence is probably much better, but don;t overlook a $8.00 part.

Based on the mileage.....replaceing the O2 is not a bad idea even if you weren't having a problem.

BTW...I have a O2 sensor socket....you need to borrow?

 

It's interesting they'd both go at the same time...
I'd start with O2, reset ecu, and go from there.

 

 

Yeah I was thinking the same thing at first. But I may just buy the MAP sensor and just return it if I don't need it. I don't have time to go back and forth to the dealer. Plus with the Drive tomorrow time is tight.

As for the socket. I'll just remove it with an open ended wrench or vise grips. Yeah I know not smart but I'll still manage.

 

not too sure you can return "electrical" items

 

Parts guys don't like it when you buy parts, try them out then return them. I know this for a fact.
