P0122 ACURA - Throttle Position Sensor 'A' Circuit Low Voltage.Possible causes- Faulty throttle position sensor. - Throttle position sensor harness is open or shorted - Throttle position sensor circuit poor electrical connection When is the code detected?An excessively low voltage from the Throttle Position Sensor (TPS) is sent to Engine Control Module (ECM).
P0122 Code - Throttle Position Sensor/Switch A Circuit Low Input
A P0122 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V).
Did you adjust it when you installed it? If the signal value is less than .17V then the PCM sets this code. Could be an open or a short to ground in the signal circuit. Or you may have lost the 5Volt reference voltage.
Symptoms may include: * Rough or low idle * Stalling * Surging * No/little acceleration * other symptoms may also be present
Causes: A code P0122 may mean that one or more of the following has happened: * TPS not mounted securely * TPS circuit short to ground or another wire * Faulty TPS * Damaged computer (PCM)
Possible Solutions: Some recommended troubleshooting and repair steps are: * Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary * Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary. * If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics. * If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.

My girlfriends car has just started with the same problem, a limp home from the garage, a sleep over night and als well next day, for a while... I spoke to Mitsubishi and they have told me the TPS (throttle positioning sensor) is on the accelorator pedle assembly. There PN for this is MN125791 and its circa £88 + VAT. After exhausting all other options I may attempt this replacement and will advise the results.
