what engine is there, , size, displacement in liters or CUInches.
3.8L V6?
p-0135 is a uSA federal code, all P0xxx are.
P1xxx are care makers owned codes, means do not read lies on the internet about, p1,p2,and codes only read your service manual
learn that bad heaters are to be fixed first 02 replaced or wires melte there.. HO2S-11 Heater Circuit (Bank 1, Sensor 1)
bad O2, front of CAT sensor bank 1,
aka. upstream.
bank one is cylinder #1 bank side.
#1 cyl is the most front cylinder on all v6 or v8.
all this is me reading your service manual to you.
p1132 Lack of HO2S-11 Switching, HO2S Signal High Input
this fails because heater is dead. so is moot here, later yes now no.
0135 first.
p1151
Lack of HO2S-21 Switching, HO2S Signal Low Input
bank 2, sensor 1. (may be caused by above otherS.)
H-hear, O 2 means oxygen sensors
11 is bank1 senser.
12 B1S2
21 b2s1
22 B2S2
SEE?
1132:
Leaking fuel injector bank 1 - EGR stuck open - Engine mechanical condition
1152: Oxygen sensor rich,
Some vehicles built prior to june 8, 2001 may exhibit a cold engine rough idle and / or a malfunction indicator lamp light with diagnostic trouble codes p0171, p0174, p1132, and p1152 in memory.
H40 DTCs P1131, P1132, P1151 AND P1152: UPSTREAM HO2S NOT SWITCHING. DTC P1130: FUEL SYSTEM NOT SWITCHING AT FUEL 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 engine 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.
Hi, 1151 is an 02 sensor code, 1131 is also 02 sensor code, 0174 lean condition bank 2, and 0171 is lean bank 1. Either this is in need of a whosale of repairs or you have computer issues, From looking at the codes i would first do a complete tune up, Including wires, And inspect for a vacume leak before replacing any 02 sensors.. Take care
p1151 indicates fuel system lean bank 2, p0174 system lean bank 2, p0305 is missfire cylinder number 5. You say no power I take that to mean that is has low power while running, if so with these codes present check your fuel pressure and pressure regulator and fuel pump, it sounds like your fuel system has low pressure and is not responding correctly. Hope this helps, let me know.
