Chrysler Repair: 99 chrysler sebring lxi - no spark, throttle position sensor, chrysler sebring

Question
QUESTION: How do you trouble shoot for no spark?  We checked cap and rotor.

ANSWER: get a manual

---------- FOLLOW-UP ----------

QUESTION: We have a manual and we are coming up with a code of P0123.  We replaced the TSP sensor and still nothing.

Answer
Symptom:
P-0123 THROTTLE POSITION SENSOR VOLTAGE HIGH
When Monitored and Set Condition:
P-0123 THROTTLE POSITION SENSOR VOLTAGE HIGH
When Monitored: With the ignition on.
Set Condition: TP sensor voltage at PCM cavity 35 goes above 4.5 volts for .704 seconds.
POSSIBLE CAUSES
TPS GROUND CIRCUIT OPEN
TPS WIRING HARNESS INTERMITTENT DEFECT
TPS WIRING HARNESS OBSERVABLE DEFECT
TPS SIGNAL CIRCUIT SHORTED TO VOLTAGE
PCM DEFECTIVE (TPS)
TPS VOLTAGE BELOW 1.0 VOLT
TPS VOLTAGE CHANGE NOT SMOOTH
TPS SIGNAL CIRCUIT OPEN
TPS SIGNAL CKT SHORTED TO 5-VOLT SUPPLY CIRCUIT

129 Ignition On, Engine Not Running
