P1132 Code Madness!!
 

I'm at my wits end with this code. When I first scanned the truck I figured it to be an easy fix and changed the front two O2 sensors just to be safe, even the the code showed only the passenger side was troublesome. Cleared the code and thought all was good. Well a few days later the check engine light came back on, and you guessed it P1132 code showed again. I started reading up on the possible causes and below is a list of what I have done so far. The truck also displays an idle drop and surge while sitting at a stop sign and the trans in drive. If I pop the trans in neutral or park the idle settles.

• Tried a new passenger side front O2 sensor thinking the first one might be defective.

• Replaced Temp Sender (Guage)

• Replaced Temp Sensor

• Replaced Throttle Position Sensor

• Replaced PCV Valve

• Sprayed Brake clean all over the place looking for vacuum leaks

• Cleaned MAF sensor

• Replaced EGR Pressure Feedback Sensor & The silicon hoses

• No audible exhaust leaks

Can anyone shed some light on this for me? I know if I take it to the dealer they'll throw another o2 sensor in it, reset the code and I'll be back in a few days.

I had a similar problem with my truck a while back so I took it in to have the codes read and they told me o2 sensors, so i replaced those and problem was still their. Took it to my buddys shop and he found that one of my vaccum hoses was collapsed on itself. 35 cents later for new piece of hose and my truck was fixed and no more idle issues. So check all of your rubber hoses to make sure everything is clear..

I didn't mention in my first post that the idle issue is hit and miss, it only does that once in a while..... its not a constant problem.

That code refers you back to P1130, which could be ALL kinds of things.

Let me know (PM me an e-mail address) if you need any 2000 schematics.

I had this issue but totaled the truck before I had a chance to fix it.

+1 Vacuum leak... On my son's mustang (with that code) it was a vacuum leak. I replaced nearly all the vacuum lines before I found out where the leak was. Also check the gaskets for the TB, IAC, and EGR. His EGR bolts were loose. After I tighten them and replaced some of the vacuum lines, reset the PCM, We have'nt had the Check Engine light since. 6 months and counting.
Hope this helps.

It could be a vacuum leak, but I cant figure out why it will drive fine for a few days, then display a rough idle for just a minute, and then go away......

I have also sprayed carb cleaner all around and have as of yet not found the leak.

Maybe your idle control valve. You can clean them like cleaning an EGR, or replace for about $50.

This issue remains unsolved..... in addition to the attempted remedies listed in the first post, I have now tried the following as well.

• Removed Throttle Body and cleaned thoroughly, replaced gasket
• Cleaned Air Filter Box and Installed New Air Filter
• Performed Compression check, all cylinders tested right at 170
• Performed Fuel Pressure check, 55psi with Key on, 60 PSI with engine started, rapped throttle and pressure remained at 60psi.
• Checked that fuel pressure held, turned key on, gauge went to 55psi, turned key off and pressure held at 55psi for 10 minutes, which tells me injectors are not leaking
• Installed new spark plugs, no single plug looked any different than the other, none fouled, none looked "Leaner" than another

This time when I checked the codes I had P1132 & P1131, o2 bank one sensor one, so now I'm getting both a lean and rich condition.....LOL!

Next I hooked the truck up to a Snap-On scanner, I made a Word file containing all the results, if you would like to download it and have a look HERE

Thanks again!!

Did you ever solve this problem? I had similar issue with P1131. Changed fuel filter, fuel pump, relay, and egr valve with no change. Finally added fuel system cleaner in gas tank and problem went away for 5 months but now is back with a P1132 code as well. I dumped another bottle of fuel cleaner in it and will see what happens.

Did you ever figure what was the issue, I’m having the exact same thing happening to my 02
, codes are p1132 and p1152, replaced iac, maf,purge valve, canister valve,both coolant temp sensor and sender, new air filter,pcv valve, spark plugs and wires and still same bs

It was a bad upstream O2 sensor.

Have you figured anything else out yet? I have these same 3 codes and issues you’re having and am not getting anywhere with it.
