Speed sensor,lamda sonda,tp sensor short to ground

code p 2122 has three reasons
1--accelerator pedal position (APP) sensor---switch D--low input==causes wiring short to ground --APP sensor /switch
2---throttle position(TP) sensor /switch D--low input===causes ---wiring short to ground--TP sensor/switch
3---engine control module (ECM) idle control---high input===causes --wiring short to positive ---TP sensor---ETS control module

code p 2127 refers to APP sensor--switch E--low input===causes wiring short to ground --- APP sensor/switch
also refers to TP switch E--high input====causes wiring short to ground ---TP sensor switch

code p 1598 is a/c pressure sensor--volts to high
code p0123 refers to throttle position(TP) sensor A/ accelerator pedal position (APP) sensor A---high input===causes wiring short to positive--TP/APP sensor---ECM
it also refers to TP sensor A APP switch A--low input====causes --wiring short to ground--Tp/APP switch---ECM

code p 0107 refers to manifold absolute pressure (MAP) sensor/ barometric pressure (BARO) sensor--low input===causes wiring short to ground---map sensor--baro sensor---ECM
code p 0122 refers to
(1)throttle position(TP) sensor A/ pedal position (APP) sensor A --low input ===causes ---wiring short to ground --TP/APP sensor/s---ECM
(2)TP switch and APP switch A--low input===causes -same as (1)
(3) TP sensor B/accelerator pedal position switch B---circuit malfunction====causes --wiring open/short to ground/short to positive--TP/APP switch--- ECM

P0068-MAMFQLD PRESSURE/THROTTLE POSITION CORRELATION
' Image
Theory of Operation
This DTC sets when an unexpected high intake manifold air flow condition exists that
can lead to increased engine speed and puts the NGC into a High Air flow Protection
limiting mode. The High Air flow Protection feature includes RPM limits for when a
Throttle and or MAP sensor limp-in fault is present.
When Monitored
During all drive modes.
Set Condition
If vacuum drops below 1.5Hg with engine RPM greater than 2000 RPM and closed
throttle. One Trip Fault. Three good trips to turn off the MIL.
Possible Causes
-VACUUM LEAK
-RESISTANCE IN THE (FS56) 5-VOLT SUPPLY CIRCUIT
-(FS56) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (Kl) MAP SIGNAL CIRCUIT
-(Kl) MAP SIGNAL CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (FS55) 5-VOLT SUPPLY CIRCUIT
-(FS55) 5-VOLT SUPPLY CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (K22) TP SENSOR NO. 1 SIGNAL CIRCUIT
-(K22) TP SENSOR NO. 1 SIGNAL CIRCUIT SHORTED TO GROUND
-RESISTANCE IN THE (K900) SENSOR GROUND CIRCUIT
-MAP SENSOR
-THROTTLE POSITION SENSOR
-PCM

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

code p0122 refers to throttle position sensor A /accelerator pedal position APP switch A --low input or switch B circuit malfunction===causes--wiring short to ground TP/APP sensor--ECM--wiring open/short to ground/short to positive--TP/APP switch --ECM. I would replace the sensor first paying particular attention to the wiring and connectors ( water ingress and dirt)

Throttle position sensor and maf sensor are displayed for these codes.Trouble Code: P0122

TP Sensor Circuit Low Input

Possible Causes:


TP sensor signal circuit is shorted to sensor ground.TP sensor signal circuit is open (except 1996-1998 models).TP sensor VREF circuit is open between sensor and PCM.TP sensor is damaged or it failed (it may be shorted).PCM is damaged or has failed.Trouble Code: P0102

MAF Sensor Circuit Low Frequency

Possible Causes:


MAF sensor element hot wire contaminated or the sensor failed.MAF sensor signal shorted to ground or ground circuit problem.MAF sensor wiring routed close to the ignition wires, generator, solenoids or electric motors.PCM has failed.Click on link to view how to replace.http://www.autozone.com/autozone/repairinfo/repairguide/repairGuideContent.jsp?pageId=0996b43f80cb3c01

code p 0122 causes are wiring short to ground , TP/APP sensor --ECM
or also wiring open/ short to ground / short to positive TP/APP---ECm
so check the wiring and connections
code p 0107 is map and /or BARO sensor --low input===causes ---wiring short to ground ---MAP sensor ---BARO sensor--ECM
