SOURCE: engine codes p1518, p0125, and p0420 for 2001 firebird

P0125 sets when engine coolant temp does not reach temperature for closed loop operation within a set amount of time.
May be a faulty sensor or thermostat.
P0420 Is related to a faulty rear 02sensor.
P1518 PCM & TAC module communication detected missing or invalid serial data.
If TAC related repair has been done, clear DTC & recheck system. It may be necessary to preform clear codes function twice to clear this DTC.
make sure starting system & charging system are functioning properly. Low voltage can cause this DTC to set. This should help. Let me know how its going.

SOURCE: i need the reason for the ecu error codes for a

P0601 means your engine computer has an internal error; P0606 means that the engine computer has stored in memory exactly the running condition( much like a "black box") that the vehicle was in when the P0606 was triggered. P1518 also relates to the PCM in the matter of low voltage.

Try testing the battery as improper voltage can cause all of these codes. Otherwise it means that your PCM has failed and either needs to be reprogrammed or replaced.

SOURCE: Have codes p0170, p0174 and p1518. Car is a 2001

P0170 and P0173 means that the system tried to go outside of the fuel trim limits.
Now this can be usually caused by a bad mass airflow sensor, but there's number of other reasons why the engine cant stay with predefined fuel trim limits. There might be an unmetered air in the system, an injector could be faulty, lambda probes might have shifted charactereistics...indeed, in most cases it's the MAF itself, but careful - i've got some returning customers after "quick and dirty" diagnosis of faulty airflow senso

2010 cobalt code po327 .have put on new sensor. light still comes on


knock sensor tells the engine computer when one or more of your engine's cylinders are "knocking", that is, exploding the air/fuel mixture in a way that delivers less power and can be damaging to the engine if prolonged. The computer uses this information to tune the engine so that it doesn't knock. If your knock sensor on Bank #1 is generating a low output voltage (perhaps under 0.5V), then it will trigger a P0327 DTC. This P0327 code may show up intermittently or the Service Engine light may be lit constantly. Other knock sensor related DTC codes include P0325, P0326, P0328, P0329, P0330, P0331, P0332, P0333, and P0334.

Why is error code p0327


Code P0327 indicates that the readings from the #1 Knock Sensor circuit are too low, is outside of its operational window and malfunctioning. Symptoms
  • Check Engine Light will illuminate
  • Engine pings on accelration
  • Engine may be running hotter or colder than normal
  • In rare cases, the engine may not exhibit noticeable symptoms
Common Problems That Trigger the P0327 Code
  • Defective Knock Sensor
  • Defective Knock Sensor Circuit or connections
  • Defective EGR System
  • Malfunctioning Cooling System
  • Rich air/fuel ratio
Common Misdiagnosis
  • Knock Sensor replaced when cause of code P0327 was a cooling system problem

Trouble codes chevy p1518


The first check should be done to the TAC module to make sure that none of the wiring near the Control Module is damaged due to chaffing. If the wiring and module appear to be in tact, the procedure below is recommended to correct the P1518
Condition/Concern:
Customers may have a concern of lack of power and engine light on. DTCs set will almost always contain a P1518 and may contain any of the following (P1516, P2108, P0220, P0120, U0107). An improperly torqued TAC module ground may be at fault. The Ground is listed as G104 on TAC module schematic which is incorrectly labeled on SI document ID 855376. The correct ground is G103. The locator for SI states that G103 is located on the left hand side which is incorrect. However, there have been field reports stating that G104 has also corrected this condition. G104 is a horizontal bolt in the rear of the left head and extremely difficult to reach. G104 should also be tightened at the same time.
There have also been field cases where ground G110 on the outer drivers side frame rail caused a P1518 code and an intermittent connection at splice 102 on the intake.
All published SI diagnostics should be followed in addition to following the recommendation listed.
Recommendation/Instructions:
Tighten ground G103 located behind the right cylinder head (passenger side) just below the head and mounted into the block. The ground uses a 13 mm bolt head mounted vertically to the engine block just above the bell housing.

I have a 2004 chevy trailblazer that gave me code p1518


P1518 CHEVROLET Description The Throttle Actuator Control (TAC) module contains data which is essential for proper TAC operation. The TAC module continuously test the integrity of this data. When the TAC module is unable to write or read data to and from random access memory (RAM), or the TAC module is unable to correctly read data from the flash memory or and internal TAC module processor fault is detected and the Detected Trouble Code (DTC) is set.

I have a 2000 Olds intrigue, and am getting error codes P0410 and P0327. What are they telling me and how should I repair them?


P0410 is a code for the EGR Valve. This can be checked by pulling vacuum on the hose attached to it while the engine is running. If the engine struggles when you do, it is working fine. P0327 is a fault on the Knock sensor. More precisely, a low voltage on the Knock Sensor. This is more than likely a severed wire or faulty sensor. I would recommend taking care of the EGR code and see if that cures both issues.

My 98 taurus has this codes what do i need to fix? p1518.p0174.p0


p0171 and p0174 are o2 sensors, There are 4 o2 sensors on a Taurus. 1 on each exhaust manifold, and 1 after each catalytic converter.
p1518 is vehicle speed, idle speed control----this means the idle air control needs fixed. you can take it off and clean carbon from it. do not push on end of air valve it will loose its adjustment. do not put in any liquid to clean, the best way is to clean end of valve with an old toothbrush or similar. also clean carbon from engine side where iac mounts. when clean put back on. you can use carb cleaner for end of valve, as for the 02 sensors, you have to find out which ones are bad first. or replace all thats up[ to you. you have to get a 02 sensor socket for 3/8 drive. then they just turn out. the best way to get them out is have the car warm.
