I have engine code 22 on my 2009 polaris ranger crew cab 4x4 TPS: open or short circuit to ground. TPS: Short circuit to battery. What do I check?

code p 0112 refers to intake air temp (IAT) sensor --circuit malfunction===cause --wiring short to graound--wiring short to positive --IAT sensor ---ECM
code p 0117 refers to engine coolant temp (ECT) sensor--circuit malfunction=== causes --coolant thermostat---wiring short to ground--wiring short to positive ---ECT sensor
code p 0122 refers to throttle position (TP) sensor A/ accelerator pedal position (APP) sensor A low input === causes wiring short to ground--TP/APP sensor --ECM
There are 3 responses to p 0122 and all refer to TP switch /sensor plus wiring open /short to ground/ short to positive
code p 0513 refers to incorrect immobilizer key=== causes immobilizer system
code p 0556 refers to brake booster pressure sensor---circuit range / performance=== causes --wiring---poor connection---brake booster pressure sensor---ECM
code p 0565 refers to cruise control master switch. off signal --malfunction === causes wiring---cruise control master switch--ECM
by reading all the codes you will see that common causes are wiring problems and ECM so may be a quick check would be to replace the ECM with a known working unit first and work back from there

What large square fuse ? The 4X4 switch get's it's B+ voltage from the four - wheel drive control module . computer controlled ! Has two relay's - transfercase hi to low & low to high ,located in the Auxiliary relay box #3 . location left side of radiator core support . Your best bet ,take it to a qualified repair shop that has a diagnostic tool that can communicate with the 4X4 control module . Read code's ! Probably has a code like one of these

Throttle Position Sensor/Switch A Circuit Range/Performance Problem


What does that mean?


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.

P0123 Code - Throttle Position Sensor/Switch A Circuit High Input
A P0123 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too high a voltage.


Symptoms may include:
Rough idle
High idle
Surging
other symptoms may also be present


A code P0123 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
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, carefully inspect all wiring and connectors that lead to the TPS. More than likely the problem is with the TPS wiring. Check the voltage at the TPS (refer to a service manual for your vehicle for this specific information). If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem. Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc.


Hope helps

Hello www_ropesmor,

This code P0123 is Throttle position sensor circuit high input.

There four basic reasons for this code.

1. An open or short to ground between the TPS (throttle position sensor) and the ECM (Engine control module).
2. A short to battery voltage between TPS and the ECM.
3. A short between the TPS wires.
4. A faulty TPS.

See below for connector diagrams.

First, with scan tool monitor TPS with throttle closed voltage should be
I f you don't have a scan tool, back probe terminal 1with a volt meter to ground and you will see the voltage as outlined above otherwise follow the steps below.


1.Check to see if there is about 5 volts at the TPS; with engine off key on disconnect the TPS back probe the harness side terminal 3 to ground with a volt meter if there is about 5 volts go to step 2 if about 5 volts if not repair the 5 volt circuit.

2. Probe the harness side terminal 2 to chassis ground with a volt meter, if voltage above .02 repair circuit 2 short to voltage. If voltage is .02 volts or below go to step 3.

3. Probe the harness side terminal 1 to ground with volt meter if below .5 volts go to step 4 if not repair short to battery between TSP harness and ECM connector

4 Turn the ignition off and disconnect the ECM connector . With an ohm meter measure the resistance between the ECM (terminal C18) and TPS ground circuit it should be below 1 ohm. Measure the resistance between the ECM (terminal C8) and TPS signal circuit it should be below 1 ohm. If not repair the open circuit.

After faulty circuit is found and repaired clear code and verify repair.







I hope this helps.
