What does DTC P1515 mean on a 2002 Chevy Trailblazer?
Circuit Description The commanded throttle position (TP), based on accelerator pedal position (APP) and possibly other limiting factors, is compared to the actual throttle position. The powertrain control module (PCM) monitors the commanded and actual throttle position. This DTC sets if the PCM detects the condition. The throttle by wire technology is great but the throttle position sensor is a common failure in the 2002 + Trailblazers. www.trailvoy.com - True Enthusiasts helping others!
How do you clear check engine codes on a 1996 subaru legacy outback?
1. Take it to the dealer or repair shop. Cost? Depends on dealer/shop. 2. Take it to an auto parts store, such as AutoZone and ask to use their OBDII scanner, or have them do it. There is NO obligation, so you don't have to buy the parts to fix the issue if you're not ready. Cost? Free 3. Under the dash, usually on the driver's side, are green and black connectors. Connect the GREEN AND BLACK connectors, turn the engine ON and drive the car over 12 mph for a few minutes. The CEL should blink slowly @ the same rate once the CEL is reset. Cost? Free and you did it yourself! P.S. To retrieve the codes, connect the Black connectors to read the codes. And turn the ignition to ON (without starting the engine). This will set the car into test modus (historic codes is displayed) in the dashboard. Just watch the blinking CEL (check engine lamp). Every flash is +10 in value (light last 1.2 second). Three flashes, is the value 30. Seperated with 3 seconds delay, before it shift over to the singular system (+1 value). Every flash is +1 in value (light last 0.2 second). Three flashes, is the value 3.

What is a throttle body on a 2004 envoy?
Envoy throttle body is like the carburetor on earlier cars except it does not supply fuel to the engine. Fuel is delivered by the fuel injectors at each cylinder. It's only function is to supply a regulated amount of air to the engine with a motor driven flapper valve. It is mounted to the plastic intake manifold on the drivers side of the engine. It is only 1 part of the fuel control system. The TB also supplies feed back to the (PCM) powertrain control module (the computer). It has the (TPS) throttle position sensor built into the unit also. When your press on the gas pedal there is no mechanical connections to the throttle body like some earlier vehicles with carburetors. The (APP) accelerator pedal position sensor is connected the gas pedal and lets the PCM and throttle body know how much gas and air to supply to the engine. When my throttle body died it threw a code P1515.
Isuzu Trooper Runs rough check engine light reduced power?
Check Engine and Reduced Power P0401, P1125, P1295, P1515 I had this problem. It drove me crazy for a while. My father previously owned the car and a professional mechanic serviced the car several times. He replaced the accelerator position sensor and whatever else he did I don't know. I don't blame the guy for not being able to fix it, as they only have so much time to figure car troubles out because they have other people to service. However, I am just someone who began to read a significant amount of information on the automobile: the engine, the brakes, the suspension, the sensors, ...the overall functioning. I did two gasket overhauls, with changing various parts to update the functioning (timing belt, plugs, several sensors, cooling system parts, charging system, pulleys, dented oil pan, oil pump, seals, valves on one of the cars, ...whatever I thought "hey, after 200,000 miles, it probably makes sense", I think it does; mind you, I did do specification checks on what needed checking with the cylinder heads). I still drive one of them (3000GT, may as well be a car you like), and a 2000 Eclipse (bought it brand new, and constantly kept up on the oil), which is now deceased (I won't go into the details), but I still pulled the engine (which still ran awesome, when I checked to see if it still ran <thank God, that would have been a total waste> and to replace this car....ta da >>> my old man gave me the 2000 Trooper. (I apologize for the long story, just want you to get an idea of what where I'm coming from) With 168,000 miles, and no timing belt change, sparks pugs, literally nothing... I went ahead and did all that plus some other stuff merely because I was deep enough into the area, or had access, rather. When I pulled off the "common chamber" which is the intake manifold I began to clean it and was surprised by a large blot of built up crap in the port for the "MAP SENSOR!!!". It ruined the sensor itself which I did not rule out right away because I just wanted to see what would happen. I left the old one in but purchased another one just in case. Low and behold a few days went by, there were no mil or reduced power for those few days but bam they did come back on. I REPLACED THE OLD MAP WITH THE NEW AND NOW IT RUNS BEAUTIFULLY, NO PROBLEMOS. It's been a couple of months now, I can take it anywhere and not worry about the limp home mode preventing me from controlling the throttle and making me feel like the only idiot being able to reach that 10 MPH limit on the way back home. I did purchase an ISUZU electronic copy of the manual (from HELM INC.) and it mentions so faintly about the correlation between the MAP reading and the throttle position. They mostly point to the TPS or Accelerator sensor predicament, so who'd of thought (I can only imagine that you can only publish a limited number of scenarios, not every possible one). The MAP reading also affects the EGR reading which was the initial check engine light cause. This was definitely what fixed mine. ON A FINAL THOUGHT: The automotive engine and the whole car itself is really really really a crazy marvel of invention. And though this world doesn't push people to realize this in its most direct way. after all, who has time right? people should make time to try and follow how it works and what keeps it working. It would save a lot of misery and aggravation.
