SOURCE: 1999 ford contour fuel pump removal

YOU will need the car on a hoist, doing it on the ground is almost impossiable, disconnect the filler neck at top, remove the straps, lower tank slow and disconnect wiring and fuel hoses, you need a special tool to remove the gas line retainer clips.

no need to replace the throttle body , and i think that you make a test before to buy any piece . disconnect the negative battery terminal few minutes, then connnect and start engine again, drive few minutes by observing the engine, if light comes again, replace only map sensor ,good luckl

4x4 4.0l V6. What are the probable causes of DTCs P0112, P0117, P0122, P0513, P0556, and P0565?


code p 0112 refers to intake air temp (IAT) sensor --circuit malfunction===cause --wiring short to graound--wiring short to positive --IAT sensor ---ECM
code p 0117 refers to engine coolant temp (ECT) sensor--circuit malfunction=== causes --coolant thermostat---wiring short to ground--wiring short to positive ---ECT sensor
code p 0122 refers to throttle position (TP) sensor A/ accelerator pedal position (APP) sensor A low input === causes wiring short to ground--TP/APP sensor --ECM
There are 3 responses to p 0122 and all refer to TP switch /sensor plus wiring open /short to ground/ short to positive
code p 0513 refers to incorrect immobilizer key=== causes immobilizer system
code p 0556 refers to brake booster pressure sensor---circuit range / performance=== causes --wiring---poor connection---brake booster pressure sensor---ECM
code p 0565 refers to cruise control master switch. off signal --malfunction === causes wiring---cruise control master switch--ECM
by reading all the codes you will see that common causes are wiring problems and ECM so may be a quick check would be to replace the ECM with a known working unit first and work back from there

My kia has 0122 code i replaced the tps and still does the samething


While the TPS fault will read p0122 the accelerator pedal position(APP) also has a say in the code p0122. It can be low input, or circuit malfunction ==the causes-- can be wiring short to ground--TP/APP sensor--wiring circuit open, short to ground/short to positive

What dose it mean when engin light falshes contstantly


Flashing Diag Code P0122
TP circuit low input
DETECTION CONDITION
• If PCM detects TP sensor voltage at PCM terminal 89 below 0.10 V after engine start, PCM determines
that TP circuit has a malfunction.
POSSIBLE CAUSE
• TP sensor malfunction
• Connector or terminal malfunction
• Open circuit between TP sensor terminal C and PCM terminal 89
• Short to ground circuit between TP sensor terminal C and PCM terminal 89
• Open circuit between TP sensor terminal A and PCM terminal 90
• Short to ground circuit between TP sensor terminal A and PCM terminal 90
• PCM malfunction

Flashing Diag Code P0123
TP circuit high input

DETECTION CONDITION
• If PCM detects TP sensor voltage at PCM terminal 89 is above 4.77 V after engine start, PCM determines
that TP circuit has a malfunction.
POSSIBLE CAUSE
• TP sensor malfunction
• Connector or terminal malfunction
• Open circuit between TP sensor terminal B and PCM terminal 91
• Short to reference voltage (Vref) supply circuit between TP sensor terminal C and PCM terminal 89
• PCM malfunction

I have a 2004 jeep wrangler and i am reading the codes p0122 p0123 and p0432 can anyone let me know what these dtc's mean and if possible how to fix what it broken


P0122 - Throttle Position (TP) Sensor Circuit Low Voltage
P0123 - Throttle Position (TP) Sensor Circuit High Voltage
without checking it 1st I would guess the TPS is most likely defective.
P0432 - Catalyst System Low Efficiency Bank 2, you may have to replace the Catalytic convertor, it may be worn out,
A WORD OF CAUTION: Don't use aftermarket cats, they tend to reset the same code due to compatibility issues, also replace the cat monitor sensor (looks like an O2 sensor) located just to the rear of the bank 2 cat converter.
