Rich is referring to your Air/Fuel ratio. Lean is too much air not enough fuel, Stoic is perfect balance between the two, Rich is too much fuel not enough air. Means more than likely you have an 02 sensor that is out.

I have a 01 ford windstar im getting acode. P1132 can you explain why


P1132
Lack of HO2S-11 Switch, Sensor Indicates Rich A HEGO sensor indicating rich at the end of a test is trying to correct for an over-lean condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. I would change both of the upstream (before the catalytic converter) O2 sensors (cylinder bank 0ne and two). 9 times out of ten this is the right guess to fix this code.

Code 1150 on a 1997 ford f 150 with a 4.2 motor


I will try to paste an article for you. Several sources indicate this is a Bank 2 O2 sensor problem and that it is failing to switch and adjust for the fuel mix. But as you can see, many defects can lead up to this O2 sensor Code 1150.

I would try to use a spray bottle of water and go around the Intake manifold and spray the water while the engine is running. An intake leak will draw water into the engine and change RPM.

If no success then try changing the O2 bank 2 sensor. You may need to wipe the computer and clear the Code. H40 DTCs P1131, P1132, P1151 AND P1152: UPSTREAM HO2S NOT SWITCHING. DTC P1130: FUEL SYSTEMicon1.png NOT SWITCHING AT FUELicon1.png TRIM (RICH OR LEAN)
Diagnostic Trouble Codes (DTCs) P1131 bank 1 (Cylinder 1) and P1151 bank 2 indicate the fuel/air ratio is correcting rich for an overly lean condition. The HO2S voltage is less than 0.45 volt. DTCs P1132 bank 1 (Cylinder 1) and P1152 bank 2 indicate the fuel/air ratio is correcting lean for an overly rich condition. The HO2S voltage is greater than 0.45 volt.
DTC P1130 and P1150 indicate the fuel control system has reached maximum compensation for a lean or rich condition and the HO2S is not switching.
DTC/HO2S Reference List
•HO2S-11 = DTCs P1131, P1132 and P1130
•HO2S-21 = DTCs P1151, P1152 and P1150
Possible causes:
Fuel system
•Excessive fuel pressure.
•Leaking fuel injector(s).
•Leaking fuel pressure regulator.
•Low fuel pressure or running out of fuel.
•Contaminated fuel injector(s)
•Vapor recovery system
Induction system
•Air leaks after the MAF.
•Vacuum leaks (vacuum lines and gaskets).
•Restricted air inlet.
•PCV system.
•Improperly seated engineicon1.png oil dipstick.
EGR System
•Leaking gasket.
•Stuck open EGR valve.
•Leaking diaphragm.
Base engine
•Oil overfill.
•Cam timing.
•Cylinder compression.
•Exhaust leaks before or near the HO2Ss.
•Check intake air system for leaks, obstructions and damage.
•Check air cleaner element, air cleaner housing for blockage.
•Verify integrity of the PCV system.
•Check for vacuum leaks. user_online.gif quote.gif post_old.gif )

My 2003 ford expedition service engine light is on an the code is reading p1132 what is wrong


Hello,
P1132 = Lack of HO2S11 switch. sensor indicates rich.
The HO2S11 is the upstream oxygen sensor. ( upstream meaning it's before the catalytic converter.)
This sensor is telling the ECM, ( electronic control module ), to increase the fuel, which is why it's indicating RICH. ( the fuel/air mix ratio should be 1 part fuel, 14.7 parts air )
The most common reason for your issues are the following.
1. Dirty air filter.
2. Faulty/dirty idle air control valve.
3. Faulty/dirty MAF, ( mass air flow ), sensor.
Until you're able to get this fixed, you are going to get poor fuel efficiency

I hope this helps you.
Thanks, Donnie

I pulled three codes from my cars computer and they where p1132 and p1131and p0135


P1132- Lack of heated oxygen sensor bank 1 switches - Sensor indicates rich
P1131- Lack of heated oxygen sensor bank 1 switches - Sensor indicates lean
P0135- Sensor heated circuit bank 1 sensor 1

Sounds to me like you need an oxygen sensor. I hope this helped and good luck.

Truck codes p1132 and p1152


Hi,

P1132 = Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 1
P1152 = Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank No. 2

It sounds to me like the oxygen sensors (between the engine and catalytic converters) should be replaced. Good luck!
