Bank 2 Sensor 1 is having problems. Hard to say exactly what because Codes are opposite for same device, showing both rich and lean.

Check aboutautomobile.com site for TSB for this part. May show clues. If not, then just change this sensor and note any wire chafing.

Please rate my info.

DTC P0300 - Random/Multiple Cylinder Misfire Detected
Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why. The symptoms may include the engine may be harder to start or may stumble / stumble, and/or hesitate.

A code P0300 may mean that one or more of the following has happened:
Faulty spark plugs or wires
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector(s)
Burned exhaust valve
Faulty catalytic converter(s)
Stuck/blocked EGR valve / passages
Faulty camshaft position sensor
Defective computer

About the solutions, if there are no symptoms, the simplest thing to do is to reset the code and see if it comes back. If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.

Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck open.


DTC P0135 - Oxygen O2 Sensor Heater Circuit Malfunction (Bank 1, Sensor 1)
This code refers to the front oxygen sensor on Bank 1. The heated circuit in the oxygen sensor decreases time needed to enter closed loop. As the O2 heater reaches operating temperature, the oxygen sensor responds by switching according to oxygen content of the exhaust surrounding it. The ECM tracks how long it takes for the oxygen sensor to begin switching. It the ECM determines (based on coolant temp) that too much time elapsed before the oxygen sensor began operating properly, it will set P0135.

You will likely notice poor fuel economy the illumination of the MIL. A code P0135 may mean that one or more of the following has happened:
O2 Heater element resistance is high
Internal short or open in the heater element
O2 heater circuit wiring high resistance
open or short to ground in the wiring harness

To solve it, you will need:
Repair short or open or high resistance in wiring harness or harness connectors
Replace oxygen sensor (cannot repair open or short that occurs internally to sensor)

In this case, it is neither left or right.
- Bank: 1= PS (Passenger Side) / 2= DS (Driver Side)
- Sensor: 1= before cats / 2= after cats

So, on a Ranger, since there is only one sensor after the cats, "sensor 2, bank 1" is the single sensor after the cats. (It may be after all of the cats or after some of them, which is the case on most late model Rangers)

In this picture, the Ranger sensor array corresponds to the second drawing down.
Sensor 2, bank 1 is "HO2S 12" (click image for zoom)...

Similarly, spark plug numbering on Fords uses the PS front cylinder for the #1 spark plug. Seems counterintuitive to me but that's Fords convention.


DTC P1132 - Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank 1
DTC P1151 - Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank 2
DTC P1152 - Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Rich - Bank 2
At one time Ford had a TSB for this concern and had a different style drain extension tube so it would direct the water away from the O2 sensor. Make sure the engine is cold and I always removed the inner fenderwell and the Trans. dipstick and tube to get better access to O2 sensor and drain. I suggest check this TSB (Technical Service Bulletin)...

DTC P1405 - Differential Pressure Feedback Electronic Sensor Circuit Upstream Hose
A P1405 may still indicate a faulty sensor, it doesn't have to be one of the common fault codes for the sensor to be bad.

Verify both hoses are connected to the DPFE sensor first; Ford has two versions of the sensor commonly used of this generation of modular engines, the first uses a pair of flexible hoses to make the connections from the EGR tube to the sensor. The hose may fail and cause this problem.

The second type of DPFE sensor is stalk-mounted. The two tubes from the EGR tube come up to the sensor and the sensor is just pushed down onto the ends of the tubes and is secured with hardware.

Inspect to see which type you have and whether there are any obvious connection failures. The Differential feedback pressure sensor is located under the hood on the drivers side.

If you locate your EGR valve you will see a tube going from it to your exhaust manifold. You will notice 2 small tubes leading from the large one feeding into a small sensor, this is the DPFE sensor which is throwing your code.

Now, the DPFE "could" be doing its job by telling you the orfice in the tube is plugged, but the DPFE is known to fail on these trucks, but it throws a code P401. It may be a good idea to try a new DPFE sensor before a new EGR tube.


Hope this helps.

P1151 code


When you have both codes at the same time, it indicates that both bank 1 & 2 O2 sensors are reporting lean condition. If only one code appeared it is usually a bad sensor, but with both codes, it is probable that it really is running way to lean. This is usually caused by a vacuum leak. Make sure you intake hose from MAF sensor (air filter box) to intake is secured and has no leaks, then move on to looking for, vacuum hoses leaking, intake gaskets leaking etc...

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)

Ford code p1152


P1151---Lack of HO2S-12 Switch (lean)

P1152--Lack of HO2S-12 Switch (rich)

Just replace both front O2 Sensors,the ones
closest to the engine--assuming they have
100,000 miles on them

Rock Auto.Com --best prices on quality parts

You should check the writing stamped on the
current sensors,they may be Bosch,but ford uses
NGK/NTK also

You will find the new ones will have longer wires
& may have different color plastic connectors
Not a problem,just curl up the wire,plug in & wire tie
away from exhaust pipes

Your code was only one side, do both,not the rear
sensors at the converter outlet,they stay almost
for ever

I have a 2001 mercury grand marquis. I had the fuel pump changed and the fuel filter changed due to a loss of power like it is running out of gas when i try to take off or when i slow down and try to speed...


P1151 is a trouble code for lack of upstream heated oxygen sensor switch bank 2 (Driver side) indicating you are running lean.
P1152 is a trouble code for same problem, but for running rich.
Hit up this site: http://www.obd-codes.com/trouble_codes/ford/p1151.php
It will tell you about several issues that could be related to the O2 sensor issue.
Since you had the pump and filter replaced, I would check the injectors/fuel pressure regulator. If the engine is starving, something along the line is preventing the necessary amount of fuel from getting in, (sputter and stall on deceleration - lean trouble code) and then a cough and fart back to life on acceleration with a mass dumping of fuel into the engine to get going again (the rich trouble code).
Once the fuel system is figured out, I would recommend an O2 sensor change as well, just in case they got gunked up through the process.

P1151 means a lean bank 2 O2 sensor
P1152 Means a rich bank 2 O2 sensor
P1309 Means miss fire detected
I would check your fuel injector for fouling
When they foul the will develop a drip
Causing a fuel fluctuation that will have O2 sensors reporting rich and lean voltage changes
This causes the pcm to adjust injector pulses making them shorter and longer.
causing more fuel or less fuel.
From this condition you may see plug fouling.
Also check for leaking or faulty fuel pressure regulator or restricted return line.
Most of the time it wont be a bad O2 sensor the O2 sensor is just doing its job.
You also have already changed the plugs and Map so there already out of the way.
If this helps please give me some feed back
Hope this works for you FixYa
