1995 ford exploere check engine light is on/loss of power

No engine problems told at all ? IS THERE?
what an easy question . RTM is what to do read the manual. on car
called service manual, pay $20 and read it online. like all techs do.

1: well the service manual covers every one of those for sure P1xxx
factory codes. 2002 year, car.
chev. 1500? 1500HD , 2500 or 3500???????? al in HD format too.
no car told but lets do 1500 only 5.3., VIN Z automatic box.
as a rule low codes are first.
140 is
HO2S Circuit Insufficient Activity Sensor 2 174 is
Fuel Trim System Lean Bank 2, humm due to above sure. 332 =
Knock Sensor (KS) Circuit Low Voltage Bank 2 so lean burns cause knock cause 174 and knocks , expected.
1133=
HO2S Insufficient Switching Bank 1 Sensor 1 oops both side fail (banks) hummmmm what can do that, sure low fuel pressure.(and loss of power)
1153 is
HO2S Insufficient Switching Bank 2 Sensor 1
P1157, is missing in my b ook(1500) or was that really P0157?????
HO2S Circuit Low Voltage Bank 2 Sensor 2 all4x O2 fail . failed, but no heater failures 02 seen.
I bet all 4 are not bad but the enigine is hyper lean fueled.

and sensor 1 is front and when it sticks lean, the fuel pressure is low (can be or all injectors are partially clogged or FPR bad.

no statement by you , LOST ENGINE POWER>?
or engine dead.
what's up doc, why are you here, scanning, just for kicks?
and PCM is loaded with old errors never reset.?????
reset them using the tool and see if some come back.
PCM 101 here. ASE. reset it.
fuel rail pressure is spec at, VIN Z engine is

(55-62?psi) VIN: (V, T,U)
the SM has 25 steps for FPR checks and injector balance tests.
the 02 sensors can not adjust for grossly wrong fuel pressure
bad fuel or clogged injectors.
or bad bad spark (plugs , boots wires bead or coil packs)
my guess is low fuel pressure but gee I can't drive it to see that./

knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor on Bank #1 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0327 DTC. This P0327 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0328, P0329, P0330, P0331, P0332, P0333, and P0334.

run the fault codes and check for transmission control, servo, solenoid problems

Is the check engine light on?

I have problem with knock sensor suzuki sx4 with code po328, what I have to do?

P0332 DTC Code - Knock Sensor 1 Circuit Low Input (Bank 2)
A knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged.

The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor on Bank #2 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0332 DTC. This P0332 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0327, P0328, P0329, P0330, P0331, P0333, and P0334.

You may notice drivability problems including fluctation engine RPM, a loss of power, and perhaps some hesitation. There may also be other symptoms.

Potential causes for a P0332 DTC include (but are not limited to):
The knock sensor is faulty and needs to be replaced
There is a wiring open/short/fault in the knock sensor circuit
The PCM/ECM has failed

Hope this helps; just keep in mind that your feedback is important and I'll appreciate your time and consideration if you leave some testimonial comment about this answer.

Have a nice day and thanks for using FixYa.

P0327 - Knock Sensor 1 Circuit Low Input Bank 1 or Single Sensor
First check the knock sensor connector. If the connector is clean and secure, replacing the knock sensor usually takes care of the problem.

- An excessively low voltage from the sensor is sent to Powertrain Control Module (ECM) or Engine Control Module (ECM)

The knock sensor is attached to the cylinder block. It senses engine knocking using a piezoelectric element. A knocking vibration from the cylinder block is sensed as vibrational pressure. This pressure is converted into a voltage signal and sent to the Powertrain Control Module (PCM) or Engine Control Module (ECM).

Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Lack/Loss of Power

Possible causes
- Knock sensor circuit short to GND.
- Knock sensor circuit short to PWR.
- Knock sensor circuit open.
- Damaged knock sensor.
- Faulty Powertrain Control Module (PCM) or Engine Control Module (ECM).


Test and check it. Hope helps.

P0327 Knock Sensor 1 Circuit Low Input (Bank 1 or Single Sensor). This is mounted right on the block with a pigtail connector attached to it. Easy to replace and cheap.

The hard starting is caused by the
P0336 Crankshaft Position Sensor. Again, not overly difficult.

Can't really say anything need the codes before I would predict anything. get codes scanned at Autozone its free.

check for vacuum hoses.
