Question about 1996 Ford Explorer

1 Answer

I have a 96 Explorer. The engine light would come

I have a 96 Explorer. The engine light would come on periodically, the code for the bank 2 front 02 sensor came up. it has been replaced. The code continues to show up. but the real problem is baffling. the Engine would occasionally not start, and I kid you not, I could push it 6 inches and it would start. this went on for a couple months. then pushing it didn't work. I plugged in my code reader and couln't get a link, unplugged several times and finally linked, erased the same code and it started. the next morning it wouldn't start, and the code reader will not link. Is this a pcm problem?

What is p2197


This code means that the O2 sensor is bad. This is the first 02 sensor on bank 2, of the engine. It is stuck on a lean setting, and needs replaced. Bank 1 refers to the side of the engine that has the #1 cylinder. Bank 2 is the opposite side of the engine. Good-Day! If you have any questions on this, Im sure any auto parts store will help you out Auto-zone Etc, They will even scan a problem code for free, as long as the check engine light is on.

Ford explorer p0059 code


P0059 .02 sensor heater control circuit draw. 02 heater resistance What this means is the 02 is shorted or open or ECM . 2nd bank sensor one. What concern me is rough accleration,either the ECM subsituted a value to protect the catalytic or you do have a engine miss and P0059 under rationality ,logic appeared.I have to say your solution is to replace 02 sensor on the second bank.To find the second bank stand in front of the vehicle the valve cover closest to the front is bank one the valve cover fartherst from the front is bank two.

My 96 nissian maxima turns off when driving down the road i try to turn the key ,lights in dash on horn blows but will not startcould it be alternater ,or what how does the 02 sensor go by functioning ...


As of 1996,all cars sold in the US were required to have an OBD-II computer interface port.
You may want to go to Advance Auto Parts, AutoZone, or Pep Boys, and get a free read
of the code(s) that you computer may be posting to help with your diagnosis.

The code coming from your vehicle's computer may be one or more of:


P0130 02 Sensor Circuit Malfunction (Bank I Sensor 1)
P0131 02 Sensor Circuit Low Voltage (Bank I Sensor I)
P0132 02 Sensor Circuit High Voltage (Bank I Sensor 1)
P0133 02 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P0134 02 Sensor Circuit No Activity Detected (Bank I Sensor 1)
P0135 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0136 02 Sensor Circuit Malfunction (Bank I Sensor 2)
P0137 02 Sensor Circuit Low Voltage (Bank I Sensor 2)
P0138 02 Sensor Circuit High Voltage (Bank I Sensor 2)
P0139 02 Sensor Circuit Slow Response (Bank 1 Sensor 2)
P0140 02 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)
P0141 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0142 02 Sensor Circuit Malfunction (Bank I Sensor 3)
P0143 02 Sensor Circuit Low Voltage (Bank I Sensor 3)
P0144 02 Sensor Circuit High Voltage (Bank I Sensor 3)
P0145 02 Sensor Circuit Slow Response (Bank 1 Sensor 3)
P0146 02 Sensor Circuit No Activity Detected (Bank I Sensor 3)
P0147 02 Sensor Heater Circuit Malfunction (Bank I Sensor 3)
P0150 02 Sensor Circuit Malfunction (Bank 2 Sensor I)
P0151 02 Sensor Circuit Low Voltage (Bank 2 Sensor I)
P0152 02 Sensor Circuit High Voltage (Bank 2 Sensor 1)
P0153 02 Sensor Circuit Slow Response (Bank 2 Sensor 1)
P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)
P0155 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 1)
P0156 02 Sensor Circuit Malfunction (Bank 2 Sensor 2)
P0157 02 Sensor Circuit Low Voltage (Bank 2 Sensor 2)
P0158 02 Sensor Circuit High Voltage (Bank 2 Sensor 2)
P0159 02 Sensor Circuit Slow Response (Bank 2 Sensor 2)
P0160 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 2)
P0161 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 2)
P0162 02 Sensor Circuit Malfunction (Bank 2 Sensor 3)

P0166 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 3)
P0167 02 Sensor Heater Circuit Malfunction (Bank 2 Sensor 3)

Note: "Bank 1" is the side of the engine with cylinder 1. "Bank 2" is the other side.

P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel


Maximas with the VE30DE and VQ30DE engines use a distributorless ignition system that is controlled by the Engine Control Module (ECM). The ECM receives a signal from the crankshaft sensor (the CPS - Crankshaft Position Sensor), and processes the signal based on inputs
from other various engine sensors, including the Oxygen sensor.
(this is the role of the O2 sensor in ECM operation).
Then the ECM sends signals to each of the individual coils in the proper firing order.
This system is more efficient than a distributor, and has fewer moving parts. The high voltage coils are directly attached to each spark plug, allowing a higher energy spark within the cylinder. A high energy spark means a faster, more thorough burning of the air/fuel mixture, which produces more power and lower emissions.


SECONDARY SPARK TEST - works for all cars, including Maxima.


1. Remove the spark plug.

2. Install the spark plug to the ignition coil/coil pack, then attach the coil wiring.

3. Ground the plug at a good ground location on the engine.

4. Crank the engine and check for spark.

5. If spark occurs, the ignition system is functioning properly.

6. If no spark exists, test the ignition coil/coil pack, power transistor and related wiring.

----------------------------------------------------------------------------------------------------------------------------
HEI Ignition Spark test - works for all cars, including Maxima.

The next level test you may want to try is a HEI (high energy ignition) spark tester kit. Cost is
about $30 at most auto parts stores. Harbor Freight Tools sells a chinese equivalent for about $16.
Place the spark tester on each of the spark plugs, and watch as the little light in the tester will
light up each time the spark plug is fired by the computer. You can actually see weak or
intermittent sparking as the motor runs - you can tell by the relative strength of the light as
you compare the intensity and duration of the light across all 6 cylinders.

If your problem were the alternator (or its built-in voltage regulator), your battery would not be
getting a proper charge, and you
wouldn't be able to start the car after a drive, since the battery would have been drained during the
drive - normally, the alternator will both charge the battery and run all electrical
features of the car during a drive.

To test your alternator, place your DMM (digital multimeter) across the battery terminals while the
car is running - it should read 13.5VDC to 14.5VDC. With the car off, you can test your battery
voltage with the same DMM - it should read 12.65 VDC (for a fully charged battery).

Alternatively, you can take your car to Advance Auto Parts, AutoZone, or Pep Boys, and they'll
attach their "charging system tester" to your car and give your car a nice test for free.
I do this with my customers' cars just to get that nifty printout of the problem. Its nice
to show a vehicle owner somethng in black & white when I'm recommending a new charging
or ignition system component (some of which can be a bit pricey).

I have a 96 k1500 chevy truck and have 4 codes that pop up on the check engine light randomly. Codes are ckp A signal intermitent, cmp out of range, idle contol rpm to high, O2 bank 1 sensor 1 insuficent...


O2 sensor cross talk bank to bank irregular, change 02 sensor(s).

Sounds like Idle air control sensor bad, All of your codes interact, I would start with 02 sensor.

I would locate a Tech II and run a diagnosis, eliminate guess work.

Engine light was on and engine idles rough.


these O2 sensors are cat convertor check sensors. id be checking cat convertors and hopefully you should try replacing if not all ready is the front bank 2, O2 sensor
if you have scanner can you see fuel trims in data display to confirm high fuel trim only on bank 2 either +-5 or more indicates problem and if bank 2 sensor 2 has fixed high 700mv reading cat no good(warm idling)

I have error codes p0156 p0161


  Check the wire harness near the top of the engine in the rear. They were good for rubbing through on the trans fill tube bracket. Judging by the code you have 4 sensors. you would be interested in the drivers side rear sensor.

Code #P0171 & code #P0174


The most common problem on a Ford with these codes is deteriorated PCV hoses. Check the hoses from the PCV valve to the intake manifold. Pay special attention to the rubber elbows. They often crack on the inside curve and the crack is hard to see.
