C0237? That is an erratic rear speed sensor fault. Is your abs light on? The speed sensor may be unplugged, wire harness damaged, sensor may be failing. The tps is part of the throttle motor assembly. Very expensive, but very easy to change.

If it is a code P0226 I would not consider it a safety issue.


Throttle position (TP) sensor C/accelerator pedal

position (APP) sensor ? - range/performance problem


Possible Causes: Accelerator cable adjustment, TP/APP sensor

Throttle position (TP) switch C/accelerator pedal position

(APP) switch ? - range/performance problem
Accelerator cable adjustment, TP/APP switch

This might only be an adjustment issue--make sure the throttle cable isn't so tight that the throttle cannot fully close.
If the cable is OK, it is probably the accelerator position sensor under the pedal.
There are procedures for testing the unit that I will paste below if you care to try them.

If you just want a shop to fix it, the part is about $50 and labor should only be 30 minutes.


Operation The sensor is made up of the two individual sensors within a single housing. Each sensor has a unique functionality to determine pedal position. The APP system along with the Powertrain Control Module (PCM) is used to calculate and control the amount of acceleration and deceleration through fuel injector control.


Removal & Installation

  1. Remove the driver-s side knee bolster.
  2. Push down on the small tab and disengage the electrical connector.
  3. Remove the pedal bolts and remove the pedal and sensor assembly.
  4. Installation is the reverse of removal.

Fig. APP sensor mounting
Testing

  1. Install a 3 amp fused jumper wire between the 5-volt reference terminal of the APP sensor and 5 volts. Install a jumper wire between the low reference terminal and a ground.
  2. Sweep the sensor through the entire range while monitoring the voltage between the signal terminal and the low reference terminal with a digital multimeter. The voltage should vary between 0.30-4.98 volts without any spikes or dropouts.
  3. If the voltage is not within the specified range or is erratic, replace the accelerator pedal assembly.

There is a Tecnical Service Bulletin (TSB) that specifically addresses codes P0120, P0220, and P1516.

It says that the TAC Module can set these codes erroneously under certain conditions. It is very likely that if your vehicle is diagnosed according to the provisions of this bulletin, the problem can be corrected without having to purchase or replace any parts.

It is Technical Service Bulletin number 03-06-04-032
Issued June 16, 2003

2004 chevy can spark plugs cause scanner to read tps on a 6.0 l gas 2004 chevy silverado


It shouldn't. The TPS sensor is voltage based on throttle position. If the plugs are bad, you should get a separate cylinder misfire code only. If you are getting a TPS code, it is likely the TPS. Remember too, it is an electronic TPS, so there is a sensor on the accelerator pedal assembly that it talks to. Make sure that's plugged in. What you can do is with the vehicle in the on position (not running) - push the pedal all the way to the floor a few times. Also, clean out the throttle body and ensure there is no gunk preventing the throttle body from opening smoothly and all the way. Good Luck.

Chevrolet Tahoe vehicles may experience a performance issue where they will not go over 15MPH. The vehicle may appear to be in "limp-in" mode, giving just enough power to get you to a shop. over-hood-250x300.gifThe codes indicate a problem with the throttle position sensor circuits and throttle actuator performance. Do NOT start replacing parts. Shops report a pattern failure in the electrical harness to these sensors. Chevrolet has issued a revised replacement harness to correct the problem. The original connector was prone to vibration and broken wires that disrupted the signal to the PCM and put the vehicle into reduced power mode.

My 1996 chevy tahoe has rougha rough idle and low r.p.m's in drive what can i do to solve this problem


I would do a full tune up first. Plugs, wires, rotor, cap and coil. If your idle is still rough consider MAP sensor, idle position sensor, or any other emissions sensors maybe suspect. They usually set codes that would trigger your "check engine" light. On the other hand check belts and tension pully if you have one. Lastley, change the fuel filter put in some injector cleaner. A good shop can test the fuel pressure from the fuel pump. I hope this can help.
