I have a 96 chevy blazer and i keep getting the error code "p-0227 throttle position sensor low input" i have cleared all error codes i have a elm 227 scan tool for my computer. i have replaced the tps on the throttle body 4 times 1,2,3 where used ones and they kept the mil light off for about a month and 1 new one kept it off for approx 2 months ??? wtf

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.
OBD Code 22 - Throttle Position Sensor Error (Signal Low) The Throttle Position sensor signals the Engine Control Module as to the current position of the engine throttle valve. The current throttle valve opening is based on the driver's input from the gas pedal. The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.
Symptoms: * Extended cranking, possible no-start condition * Lack of power * Erratic transmission operation
Common Problems: * A failed Throttle Position Sensor (TPS) would be the most common causes for code 22 * Testing the TPS circuit would involve checking voltage and ground from the ECM-5v is the normal reading between the ECM reference circuit and the ECM ground circuit at the TPS connector. Checking the TPS signal circuit to the ECM would involve monitoring the TPS signal on a scan tool while jumping the 5v reference and the signal circuits. The TPS reading should go from high when the circuit is "jumpered" to low when the jumper is removed.
Hi, the indication is that your computer is not receiving a good signal from the knock sensor. Recommend you check the connector on the sensor and the wire. Also make sure the sensor isn't loose in the block. If those look good, you may want to just replace the sensor. A new one is $30 at autozone. Without the knock sensor signal, the computer will default the ignition timing toward a less fuel efficient value. The sensor looks like the picture below and is mounted in the engine block. You may have 2 knock sensors--one on each side of the engine. Sorry, but I could not find a good picture of the location. I will keep looking for one, though.
Throttle position sensor TPS is not behaving. Codes p1543 and p1565 indicate the throttle position is too low... as if disconnected. The other codes are as a result of the EECU noting the disparity between the throttle input signal and the expected input from the engine speed and distributor/cam sensor. Check that the connector and wiring to the TPS. If these are OK then it is the TPS that needs to be changed.
yes it can cause.A worn sensor may cause a skip or drop in the reading when the throttle opens, If the TPSis open, the computer will think the throttle is closed all the time as its faulty and engine will not get start up.
