Code Help
Ok I have been having numerous problems with my car. I ran the codes today. The codes I got were.
51 - Engine Coolant Temperature Circuit Open (M,O)
53 - Throttle Position Sensor Circuit Above Maximum Voltage (M,O)
54 - Intake Air Temperature/Air Charge Temperature Circuit Open (M,O,R)
Will replacing these senors solve the problem with the open circuits and the TPS voltage being too high? I really hate to just throw money/parts at it in hopes it might work. Thanks.

Not necessarily....... looks like you may have a problem (wiring, open SIGRTN circuit) common to/affecting those sensors. You need to verify resistance of the SIGRTN wire/terminal at each connector of those sensors to ground. If the resistance is > 5 ohms, you have an open in the SIGRTN circuit. You could also check resistance at the ECT and ACT sensors terminals ...... if their resistance falls within the value/temperature given in the table below...... the sensors are OK, the problem would be elsewhere.
