My 2006 chevy malibu doesn't want to shift gears codes P0121 & P0101 & P0420 transmission place said it's not the transmission.


P0101....Mass or Volume Air Flow Circuit Range/Performance Problem
P0121 - Throttle Position Sensor/Switch A Circuit Range/Performance Problem.
P0420 - Catalyst System Low Efficiency
there is criteria that enable trans shift
solve codes problems then transmission will shift normaly

What does P0121 mean


its a throttle position sensor, you have an electronic gas pedal not and not a normal cable.type

Whats p0121 solution?


code p0121 refers to throttle position sensor(TP) A/ accelerator pedal position (APP) sensor A --range performance problem===causes---accelerator cable adjustment---TP/APP sensor ---wiring
check that the cable is not broken and/ or replace the sensor.

My battery died, I replaced it and now I get only Error Codes P0121 and P0573. The vehicle does not act like anything is wrong in either case...Throttle works just fine...and I don't have cruise control....


P0121 is : throttle / pedal position sensor/switch A circuit range/performance problem
P0573 is : cruise control /brake switch A circuit high
first check : there is two switch on brake pedal linkage one for brake light and the second with rubber hose for cruise control
try to push switch toward brake pedal to ajust
tps code P0121 check for wires if they are cut
hope it helps

Error code p0121


I cannot give you any specific information for your vehicle because you failed to mention YEAR, MAKE, MODEL, ENGINE SIZE, TRANSMISSION TYPE, etc..
However, the standardized description of Diagnostic Test Code (DTC) P0121 according to SAE J2012 (Revised December 2007) is "Throttle/Pedal Position Sensor/Switch "A" Circuit Range/Performance".

P0121 generic throttle/pedal position sensor a circuit range/ performance


P0121 - Throttle Position Sensor/Switch A Circuit Range/Performance Problem

The Throttle position sensor is a potentiometer that measures the amount of throttle opening. As the throttle is opened, the reading (measured in volts) goes up. The powertrain control module (PCM) supplies a 5 Volt reference signal to the throttle position sensor (TPS) and usually a ground also. A general measurement is: at idle = .5 Volts; full throttle = 4.5 Volts. If the PCM detects that the throttle angle is greater or less than it should be for a specific RPM, it will set this code.

Potential Symptoms: Symptoms of a P0121 trouble code could include:
Malfunction Indicator Lamp (MIL) illumination (Check Engine Light or Service Engine Soon light)
Intermittent stumble on acceleration or deceleration
Blows black smoke on acceleration
No start

Causes: A code P0121 may mean that one or more of the following has happened:
TPS has intermittent open or short internally
Harness is rubbing and causing an open or short in the wiring
Bad connection at the TPS
Bad PCM (less likely)
Water or corrosion in connector or sensor

Possible Solutions:
1. If you have access to a scan tool, see what the idle and WOT (wide open throttle) readings are for the TPS. Check if they're close to the specifications mentioned above. If not, then replace the TPS and re-check.
2. Check for an intermittent open or short in the TPS signal. To do that, you can't use a scan tool. You'll need an oscilliscope. The reason is because scan tools take samplings of many different readings over just one or two data lines and can miss an intermittent drop out. Hook up your oscilliscope and watch the signal. It should sweep up and down smoothly with no drop outs or spikes.
3. If no problems were noticed, perform a wiggle test. Do this by wiggling the connector and harness while watching the pattern. Does it drop out? If so, replace TPS and re-check.
4. If you have no TPS signal, check for 5 Volt reference at the connector. If it's present, check the ground circuit for open or shorts.
5. Make sure the signal circuit isn't 12V. It should never have battery voltage. If it does, trace circuit for short to voltage and repair.
6. Look for any water in the connector and replace TPS as necessary.

Dtc code p0121 and p2135 2007 chevy malibu


both codes refer to the throttle position sensor, the sensor is at the throttle plate, on the side of the throttle body. to test remove the connector to sensor, use a ohms meter to test. put 1 lead to top connection and the other to the bottom one. move throttle and the needles on the ohms meter should move very even, move throttle slow to get a good reading, needle should move without no hesitation, if the test is bad replace tps sensor. if the sensor gets to bad, it can have an effect on transmission shifting. after fixing sensor have the light turned of with an obd2 scanner.

My check engine light is on. The code is P0121


I believe all the Mopar OBDC codes are the same. A list of the 2001 codes were posted on a PT Cruiser site here: 2001 Chrysler codes

Your error says the throttle position sensor and MAP sensor disagree with each other
