brobradh77 Posted May 12, 2009 Report Share Posted May 12, 2009 I started my truck at lunch and was in limp mode...I pulled the codes and they were P0220 TP Sensor 2 circuit P2135 TP Sensor 1-2 Correlation I tried to clear the codes but it wouldnt..I uunplugged the TB Harness and replugged it in and the P0220 Code cleared which was causing the limp mode but the other code remained...I was able to clear that one when I got home but am about to head to work and was curious what would have triggered those codes. Any ideas? Quote Link to comment Share on other sites More sharing options...
delay18 Posted May 12, 2009 Report Share Posted May 12, 2009 Ok that showed up like crap. Sorry about that. I was trying to post the DTC trouble tree for each. Quote Link to comment Share on other sites More sharing options...

brobradh77 Posted May 12, 2009 Author Report Share Posted May 12, 2009 Ok that showed up like crap. Sorry about that. I was trying to post the DTC trouble tree for each. lol..thanks...It hasnt showed back up..Last night me and Rick from trick turbos was messing around under the hood in the area of my TB so we may have bumped it enough to jar it loose...I dunno.

Fireman31 Posted May 12, 2009 Report Share Posted May 12, 2009 Brad, the AllData info on these codes, for your reference........ DTC P0220 CIRCUIT DESCRIPTION The throttle position (TP) sensor incorporates 2 ratiometric TP sensors into one housing. TP sensor 1 and TP sensor 2 each have a 5-volt reference circuit supplied by the throttle actuator control (TAC) module. The TAC module supplies each TP sensor with a low reference circuit. Each TP sensor supplies the TAC module with a signal voltage that is proportional to the throttle blade position. Both TP signal voltages increase as the throttle blade is opened. The TP sensor 1 and the accelerator pedal position (APP) sensor 1 share a 5-volt reference circuit that is bussed within the TAC module. The TP sensor 2 and the APP sensor 2 share a 5-volt reference circuit that is also bussed within the TAC module. When this DTC sets, the Reduced Engine Power indicator will be displayed. This DTC incorporates the following diagnostic tests: The TP sensor 2 signal circuit voltage out of range The throttle blade minimum position for the TP sensor 2 out of range The 5-volt reference of the TP sensor 2 tests out of range. If the PCM detects one or more of the TP sensor 2 tests are out of range, DTC P0220 sets. DTC DESCRIPTOR This diagnostic procedure supports the following DTC: DTC P0220 Throttle Position (TP) Sensor 2 Circuit CONDITIONS FOR RUNNING THE DTC DTCs P2108 or U0107 are not set. The ignition switch is in the Crank or Run position. The ignition voltage is more than 5.23 volts . The TP sensor 2 signal voltage test runs continuously once the above conditions are met. The throttle blade minimum position for the TP sensor 2 test runs once when the ignition is turned ON and the above conditions are met. The 5-volt reference of the TP sensor 2 voltage test runs continuously once the above conditions are met. CONDITIONS FOR SETTING THE DTC The TP sensor 2 signal voltage is less than 0.28 volts , or more than 4.6 volts , for more than 0.1 second .OR The TP sensor 2 minimum throttle blade position is less than 0.28 volts , or more than 0.81 volts , for less than 1 second.OR The 5-volt reference circuit of the TP sensor 2 is less than 0.5 volts for more than 0.01 second . ACTION TAKEN WHEN THE DTC SETS The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails. The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame and/or the Failure Records. The control module commands the TAC system to operate in the Reduced Engine Power mode. A message center or an indicator displays Reduced Engine Power. Under certain conditions the control module commands the engine OFF. CONDITIONS FOR CLEARING THE MIL/DTC The control module turns OFF the malfunction indicator lamp (MIL) after 3 consecutive ignition cycles that the diagnostic runs and does not fail. A current DTC, Last Test Failed, clears when the diagnostic runs and passes. A history DTC clears after 40 consecutive warm-up cycles, if no failures are reported by this or any other emission related diagnostic. Clear the MIL and the DTC with a scan tool. DIAGNOSTIC AIDS Inspect the TAC module connectors for signs of water intrusion. If water intrusion occurs, multiple DTCs may set without any circuit or component conditions found during diagnostic testing. When the TAC module detects a condition within the TAC system, more than one TAC system related DTC may set. This is due to the many redundant tests run continuously on this system. Locating and repairing one individual condition may correct more than one DTC. Disconnecting components during testing may set additional DTCs. Remember this if you review the stored information in Capture Info. If this DTC is determined to be intermittent, refer to Testing for Intermittent Conditions and Poor Connections. DTC P2135 CIRCUIT DESCRIPTION The throttle position (TP) sensor incorporates two ratiometric TP sensors into one housing. TP sensor 1 and TP sensor 2 each have a 5-volt reference circuit supplied by the throttle actuator control (TAC) module. The TAC module supplies each TP sensor with a low reference circuit. Each TP sensor supplies the TAC module with a signal voltage that is proportional to the throttle blade position. Both of the TP signal voltages increase as the throttle blade is opened. The TP sensor 1 and the accelerator pedal position (APP) sensor 1 share a 5-volt reference circuit that is bussed within the TAC module. The TP sensor 2 and the APP sensor 2 share a 5-volt reference circuit that is also bussed within the TAC module. When this DTC sets, the Reduced Engine Power indicator will be displayed. This DTC incorporates the following diagnostic tests: The TP sensor 1 and the TP sensor 2 correlation The throttle blade minimum position correlation between the TP sensor 1 and the TP sensor 2 The TP sensor 1 signal shorted to a 5-volt reference, a ground, or the TP sensor 2 signal circuit If the powertrain control module (PCM) detects one or more of the TP sensor 1 tests are out of range, DTC P2135 sets. DTC DESCRIPTOR This diagnostic procedure supports the following DTC: DTC P2135 Throttle Position (TP) Sensor 1-2 Correlation CONDITIONS FOR RUNNING THE DTC DTCs P2108 or U0107 are not set. The ignition switch is in the Crank or Run position. The ignition voltage is more than 5.23 volts . The TP sensor 1 to TP sensor 2 correlation test runs continuously. The throttle blade minimum position correlation test runs once after the ignition is turned ON. The TP sensor 1 signal circuit short test runs continuously. CONDITIONS FOR SETTING THE DTC The TP sensor 1 to TP sensor 2 correlation error is more than 6 percent for more than 0.14 second . OR The PCM detects a short on the TP sensor 1 signal circuit for more than 0.10 second . ACTION TAKEN WHEN THE DTC SETS The control module illuminates the malfunction indicator lamp (MIL) when the diagnostic runs and fails. The control module records the operating conditions at the time the diagnostic fails. The control module stores this information in the Freeze Frame and/or the Failure Records. The control module commands the TAC system to operate in the Reduced Engine Power mode. A message center or an indicator displays Reduced Engine Power.
