2004 Expedition, 4.6L- Codes P2195,96,97,98 and P0132 and P0152

[Etk999]

I've already changed out the 02 sensors and done a vacuum leak check. Replaced PCV valve and hose with elbow already. Plugs are new. Any ideas? The truck is stalling/hesitating shortly after start up and driving begins. Idle is slightly rough but nothing major. Changing out the fuel filter next.

Although its an expensive proposition to think about, it could be related to one or more bad coil packs.

If you haventh already, I would Google the codes or maybe someone else here can chime in on these codes?

I had rhe ssamissues you are describing on my 06 XLT aboit a year ago. Changed all 8 plugs and coil packs and haven't had any issues since. I took it to a shop to have mine done because of the issue with sparck plugs breaking in these motors. Total for the job parts and labor was around $1200.

Also, If you go that route, I highly recommend going ahead and shelling out for genuine Motocraft parts as these motors are very particular and fineky when aftermarket stuff is put in or on them.

Generally, from past experience with the coil packs (I hate them), everything kinda dies and you get a misfire code when it stalls and it's hard to crank. I'm not getting a misfire code and it cranks right up. Hoping it's not the PCM or injectors.
Note: I'm certainly not a mechanic though

I agree with your assessment. I was speculating not knowing what the codes indicated. Lean/rich could be an issue with a faulty fuel injector. Had a cracked one that I wasn't aware of for quite some time. Check engine code came back as a misfire on cylinder 8. Mechanic figured it out for me and replaced the affected O2 sensor and fuel injector and all was well. About a week later it threw another code indicating that the catalytic converter was (my words) toast. That is the point at which I decided to sell the truck as it had been wrecked and I couldn't see spending $4500 to have body work fixed in addition to $1000 for a new catalytic converter not counting labor costs.

You've got generic codes for lean conditions, which is one of the reasons for rough Idle, and driveability issues. Your going to need to hook up to a scanner that can read fuel trim. My guess is their high
You most likely have intake leaks, and your computer is trying to compensate, with richer signals from 02 sensors. I'm betting after smoking motor theirs an intake gasket, or egr leak. You could be chasing your tail on this one, trying to do yourself. A bad computer will usually spit out even more codes. Yours aims more towards lean conditions.

Definitely chasing my tail. Thanks !!

With the engine running check fuses #32, 33 and 34 for voltage into and out if the fuse see attached link

P2195 - Lack of HO2S-11 Switch, Sensor Indicates Lean
A Heated Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time.

• Electrical:
• Short to VPWR in the harness or HO2S.
• Water in the harness connector.
• Open/shorted HO2S circuit.
• Corrosion or poor mating terminals and wiring.
• Damaged HO2S.
• Damaged PCM.
• Fuel System:
• Excessive fuel pressure.
• Leaking/contaminated fuel injectors.
• Leaking fuel pressure regulator.
• Low fuel pressure or running out of fuel.
• Vapor recovery system.
• Induction System:
• Air leaks after the MAF.
• Vacuum Leaks.
• PCV system.
• Improperly seated engine oil dipstick.
• EGR System:
• Leaking gasket.
• Stuck EGR valve.
• Leaking diaphragm or EVR.
• Base Engine:
• Oil overfill.
• Cam Timing.
• Cylinder compression.
• Exhaust leaks before or near the HO2S(s).

P2196 - Lack of HO2S-11 Switch, Sensor Indicates Rich
A Heated Oxygen (HO2S) 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. See the possible causes for DTC P2195.
P2197 - Lack of HO2S-21 Switch, Sensor Indicates Lean
A Heated Oxygen (HO2S) sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. See the possible causes for DTC P2195.
P2198 - Lack of HO2S-21 Switch, Sensor Indicates Rich
A Heated Oxygen (HO2S) 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. See the possible causes for DTC P2195.


P0132 - HO2S Sensor Circuit High Voltage (HO2S-11)
The HO2S signals are monitored for an over voltage fault. The code is set when the HO2S signal voltage is 1.5 volts or greater.

• HO2S Signal Circuit shorted to Heater Power inside of HO2S sensor.
• HO2S Signal Circuit shorted to VPWR or VREF in harness.
• PCM failure.

An HO2S PID switching across 0.45 volt from 0.2 to 0.9 volt indicates a normal switching HO2S. An HO2S PID voltage of 1.5 volts or greater indicates a short to power.

P0152 - HO2S Sensor Circuit High Voltage (HO2S-21)
See the description for DTC P0132. See the possible causes for DTC P0132. See the diagnostic aids for DTC P0132.
