Project 11

2002 Ford Focus SVT

Introducing the 11th Ford Focus project for Focus Rush. This car was not at all a planned purchased. With project 10 still in the works, this car may take a little longer to get around to everything before it’s completed and 100% roadworthy.

After a 6 1/2 hour drive from Dallas, TX, to Springfield, MO, we pulled up to the house where it was sitting and were luckily able to drive the car onto the trailer without issue. 6 1/6 hours back, we drove it off the trailer and into the driveway where it will live for a bit. In the meanwhile, this vehicle will benefit greatly from another parts SVT that is owned by Ford Focus OG RIck Lundstrom that has a plethora of parts that will match this car perfectly. We’ve been able to identify almost all of the issue so far with the help of three sets of OG Focus owner’s eyes, and an SVT XCal.

The previous owner was under the impression that the engine was bad due to a spun bearing, or something internal. After listening to it and running the codes, that the internals of the engine are just fine.

Here’s the list of codes:

P0125 - Insufficient Coolant Temperature For Closed Loop Fuel Control Indicates the ECT or CHT sensor has not achieved the required temperature level to enter closed loop operating conditions within a specified amount of time after starting engine. Insufficient warm up time
Low engine coolant level
Leaking or stuck open thermostat
Malfunctioning ECT sensor
Malfunctioning CHT sensor
Refer to Thermostat Monitor in Section 1, Description and Operation, for system information.

P0133 - HO2S Sensor Circuit Slow Response (HO2S-11) The HEGO Monitor checks the HO2S Sensor frequency and amplitude. If during testing the frequency and amplitude were to fall below a calibrated limit, the test will fail. Contaminated HO2S sensor.
Exhaust leaks.
Shorted /open wiring.
Improper fueling.
MAF sensor.
Deteriorating HO2S sensor.
Inlet air leaks.
Access HO2S test results from the Generic OBD-II menu to verify DTC.

P0135 - HO2S Sensor Circuit Malfunction (HO2S-11) During testing the HO2S Heaters are checked for opens/shorts and excessive current draw. The test fails when current draw exceeds a calibrated limit and/or an open or short is detected. Short to VPWR in harness or HO2S.
Water in harness connector.
Open VPWR circuit.
Open GND circuit.
Low battery voltage.
Corrosion or poor mating terminals and wiring
Damaged HO2S heater.
Damaged PCM.
Wiring.
Damaged HO2S heater.
Damaged PCM.

P0136 - HO2S Sensor Circuit Malfunction (HO2S-12) The downstream HO2S sensor(s) are continuously checked for maximum and minimum voltages. The test fails when the voltages fail to meet the calibrated limits. Pinched, shorted, and corroded wiring and pins.
Crossed sensor wires.
Exhaust leaks.
Contaminated or damaged sensor.

P0304 - Cylinder 4 Misfire

P1000 - CEL on

P1131 - Lack of HO2S-11 Switch, Sensor Indicates Lean A HEGO sensor indicating lean at the end of a test is trying to correct for an over-rich condition. The test fails when the fuel control system no longer detects switching for a calibrated amount of time. See Possible Causes for DTC

P1381 - Camshaft Timing Advanced

P1383 - Camshaft Timing Retarded

Initial Repairs Needed
